Chapter 1 The Living World
This chapter expounds the central concepts. The living world is wealthy in an assortment. A great many plant and animal species have been distinguished and depicted to date, yet incalculable more remain yet to be found. The taxonomic investigations of different species of plants and animals are valuable in agriculture, forestry, industry, and all in all for knowing our resources and their diversity. Taxonomists have an assortment of taxonomic aids to encourage the identification, naming and classification of organisms.
Chapter 2 Biological Classification
The chapter has characteristics of Kingdoms Monera, Protista and Fungi of the Whittaker system of classification. The topic further discusses The Kingdoms Plantae and Animalia, commonly known as plant and animal kingdoms, respectively, will be dealt with individually in Chapters 3 and 4. You will also learn about Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Plantae, Kingdom Animalia, Viruses, Viroids, and Lichens.
Chapter 3 Plant Kingdom
In the previous chapter, we took a gander at the broad classification of living organisms under the framework proposed by Whittaker (1969) wherein he recommended the Five Kingdom classification viz. Monera, Protista, Fungi, Animalia, and Plantae. In this section, we will dig into detail with additional classification inside the Kingdom Plantae or the 'plant kingdom'. Additionally, you will learn concepts, for example, Algae, Bryophytes, Pteridophytes, Gymnosperms, Angiosperms, Plant Life Cycles and Alternation of Generations.
Chapter 4 Animal Kingdom
At the point when we glance around, we notice various animals with various structures and forms. Over 1,000,000 species of animals have been portrayed as of not long ago, the requirement for classification turns into even more significant. The classification likewise helps in doling out a methodical situation to newly described species. It likewise teaches different topics, for example, Basis of Classification, Classification of Animals and many more.
Chapter 5 Morphology of Flowering Plants
For any useful endeavor at classification and at seeing any higher plant (or so far as that is concerned any living organism), we need to know standard technical terms and standard definitions. We likewise need to think about the potential variations in different parts, found as adaptations of the plants to their environment, e.g., adaptations to different habitats, for protection, climbing, storage. It additionally clarifies themes, for example, the root, stem, leaf, inflorescence, flower, fruit, seed, semi-technical depiction of a regular flowering plant, the portrayal of some significant families.
Chapter 6 Anatomy of Flowering Plants
This section presents the internal structure and functional association of higher plants. Plants have cells as their building unit, cells are coordinated into tissues, and this way, the tissues are coordinated into different pieces of the plant. Inside angiosperms, the monocots and dicots are anatomically unique. Internal structures likewise show transformations to various conditions. It incorporates themes, for example, The Tissues, The Tissue System, Anatomy of Dicotyledonous and Monocotyledonous Plants, Secondary Growth, and the sky's the limit from there.
Chapter 7 Structural Organisation in Animals
In the first chapters, we went over an enormous assortment of organisms, both unicellular and multicellular, of the animal kingdom. In unicellular organisms, all capacities like digestion, respiration and reproduction are performed by a solitary cell. In the unpredictable assemblage of multicellular animals, similar fundamental functions are completed by various groups of cells efficiently. All complex animals comprise just four fundamental sorts of tissues. These tissues are coordinated in explicit areas to frame organs –, for example, the stomach, lung, heart and kidney.
Chapter 8 Cell The Unit of Life
The chapter deals with questions such as "What would it be that makes an organism living?" or, "What could it be that an inanimate item doesn't have which something living has?" The response to this is the presence of the basic unit of life – the cell in every living organism. All organisms are made out of cells. Some are made out of a single-cell and are called unicellular organisms. Interestingly, others, similar to us, are made out of numerous cells and are known as multicellular life forms.
Chapter 9 Biomolecules
There are various living organisms in our biosphere. This chapter further deals with How to Analyse Chemical Composition? The Primary and Secondary Metabolites along with Biomacromolecules, Proteins, Polysaccharides, to name a few.
Chapter 10 Cell Cycle and Cell Division
Growth and reproduction are qualities of cells, to be sure of all living organisms. All cells reproduce by separating into two, with each parental cell offering ascend to two daughter cells each time they partition. These recently framed daughter cells would themselves be able to develop and partition, offering to ascend to another cell population that is shaped by the growth and division of a solitary parental cell and its progeny. Such patterns of growth and division permit a solitary cell to frame a structure comprising millions of cells. Other subtopics referenced in the chapter are Cell Cycle, M Phase, Significance of Mitosis, Meiosis, Significance of Meiosis.
Chapter 11 Transport in Plants
Subjects in this chapter incorporate Means of Transport, Plant-Water Relations, Long Distance Transport of Water, Transpiration, Uptake and Transport of Mineral Nutrients, Phloem, Transport: Flow from Source to Sink. Plants acquire an assortment of inorganic elements (particles) and salts from their environmental factors, mainly from water and soil. In higher plants, there is a vascular framework, including xylem and phloem, liable for translocation. Phloem is answerable for the transport of food (fundamentally) sucrose from the source to the sink. The pressure-flow theory clarifies the translocation in the phloem.
Chapter 12 Mineral Nutrition
This chapter centers chiefly around inorganic plant nutrition, wherein we will study the techniques to recognize elements fundamental to the growth and development of plants and the standards for setting up the centrality. We will likewise study the part of the fundamental elements, their significant lack of manifestations, and the system of absorption of these essential elements. The chapter additionally gives a short prologue to the centrality and the system of biological nitrogen obsession.
Chapter 13 Photosynthesis in Higher Plants
All animals, including human beings, rely upon plants for their food. The green plants make or instead orchestrate the food they need through photosynthesis and are along these lines called autotrophs. Green plants do 'photosynthesis', a physicochemical cycle that uses light energy to drive the combination of organic mixes. Photosynthesis is significant because of two reasons: it shapes the reason for all realized food chains on earth. This chapter focuses on the anatomy of the photosynthetic hardware and the different responses that change light energy into chemical energy.
Chapter 14 Respiration in Plants
This chapter manages cell breath or the component of the breakdown of food materials inside the cell to deliver energy and the catching of this energy for the blend of ATP. This chapter likewise expounds themes; for example, "Do Plants Breathe?". The concepts of Glycolysis, Aerobic Respiration, The Respiratory Balance Sheet, Fermentation, Amphibolic Pathway, and Respiratory Quotient are covered in the topic.
Chapter 15 Plant Growth and Development
We have just considered the association of a flowering plant in Chapter 5. In this chapter, we will investigate a portion of the variables which administer and control these formative cycles. These variables are both intrinsic (interior) and extrinsic (outside) to the plant. The various other subtopics in the chapter are Growth Differentiation, Dedifferentiation and Redifferentiation, Development, Plant Growth Regulators, Photoperiodism, Vernalisation and then some.
Chapter 16 Digestion and Absorption
Food is the foremost necessity of every single living creature. The significant segments of our food are sugars, proteins, and fats. Nutrients and minerals are likewise needed in little amounts. Food gives energy and natural materials to develop and fix tissues. The water we take in assumes a significant part in metabolic cycles and forestalls the parchedness of the body. Our body can't use bio-macromolecules in food in their unique structure. They must be separated and changed over into straightforward substances in the stomach related framework. This cycle of change of complex food substances to straightforward absorbable structures is called absorption and is done by our digestive system, by mechanical and biochemical techniques.
Chapter 17 Breathing and Exchange of Gases
As you have perused before, oxygen is used by the organisms to by implication, separate basic molecules like glucose, amino acids, fatty acids, and so forth, to infer energy to perform different exercises. Carbon dioxide, which is unsafe, is additionally delivered during the above catabolic reactions. It is, consequently, apparent that oxygen must be given continuously to the cells, and carbon dioxide created by the cells must be delivered out. This cycle of exchange of oxygen from the atmosphere with carbon dioxide delivered by the cells is named as breathing. It is otherwise called respiration.
Chapter 18 Body Fluids and Circulation
We have discovered that all living cells must be given nutrients, oxygen and other basic substances. Additionally, the waste or unsafe substances delivered must be taken out regularly for a good working of tissues. Blood is the most ordinarily utilized body liquid in the more significant part of the higher organisms, including people. Another body liquid, lymph, likewise helps in the transport of specific substances. In this section, we will investigate the arrangement and properties of blood and lymph (tissue liquid), and the mechanism of dissemination of blood is additionally clarified thus.
Chapter 19 Excretory Products and their Elimination
The part covers themes, for example, Human Excretory System, Urine Formation, Function of the Tubules, Mechanism of Concentration of the Filtrate, Regulation of Kidney Function, Micturition, Role of different Organs in Excretion, Disorders of the Excretory System and that's just the beginning.
Chapter 20 Locomotion and Movement
Movement is one of the critical highlights of living creatures. Animals and plants show a broad scope of movements. Such voluntary movements are called locomotion. Strolling, running, climbing, flying, and swimming are large types of locomotory movement. Locomotory structures need not be unique in relation to those influencing different sorts of movements. Techniques for locomotion performed by animals shift with their habitats and the interest of the circumstance. Locomotion is needed for an assortment of reasons, for example, discovering food, cover, mate, appropriate breeding grounds, ideal climatic conditions or to escape from hunters.
Chapter 21 Neural Control and Coordination
Coordination is the cycle through which at least two organs interface and supplement the elements of each other. In our body, the neural framework and the endocrine framework together coordinate and incorporate all the exercises of the organs with the goal that they work in a synchronised style. The neural arrangement of humans, instruments of neural coordination like transmission of nerve impulse, impulse conduction across a synapse and the physiology of reflex activity is discussed.
Chapter 22 Chemical Coordination and integration
We have, as of now discovered that the neural framework gives highlight point quick coordination among organs. Neural coordination is quick yet brief. As the nerve strands do not innervate all cells of the body and the cell capacities should be ceaselessly managed; an uncommon sort of coordination and incorporation must be given. Hormones do this capacity. The neural framework and the endocrine framework together coordinate and control the physiological capacities in the body.
