Biology

Plants do require oxygen to respire, the process in return gives out carbon dioxide. Unlike humans and animals, plants do not possess any specialized structures for exchange of gases, however, they do possess stomata (found in leaves) and lenticels (found in stems) actively involved in the gaseous exchange.In this chapter we are going to discuss about Electron transport system and oxidative phosphorylation,Fermentation,Glycolysis,Tricarboxylic acid cycle.

Transportation is the process that involves the movement of water and necessary nutrients to all parts of the plant for its survival. In this chapter students will learn about means of transport,long distance transport of water,transportation in plants and transpiration

Green plants carry out 'photosynthesis', a physico-chemical process by which they use light energy to drive the synthesis of organic compounds. Ultimately, all living forms on earth depend on sunlight for energy. The use of energy from sunlight by plants during photosynthesis is the basis of life on earth.In this chapter students will learn about C4 pathway, Calvin cycle ,Factors affecting photosynthesis and Light reactions.

Biomolecules are an organic molecule that includes carbohydrates, protein, lipids, and nucleic acids. They are important for the survival of living cells. Some valuable biomolecules have huge demand, which cannot be fulfilled from their renewable resources.In this chapter students will learn about lipids, nucleic acids and proteins.

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That is because all cells are surrounded by a structure called the cell membrane which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments. In this chapter students will learn about cell theory, Endoplasmic reticulum ,Mitochondria and ribosomes.

The cell is the basic structural and functional unit of any living being. It is the fundamental building block, which combined with similar cells forms a tissue and organs. A cell comprises several organelles. In this chapter students will learn about cell cycle and cell division. Particularly meiosis I, meiosis II, mitosis and phases of cell cycle

In our body the neural system and the endocrine system jointly coordinate and integrate all the activities of the organs , so that they function in a synchronized fashion. The neural system provides an organized network of point-to-point connections for quick coordination.In this chapter students will learn about central nervous system,eye, anatomy of ear and transmission of nerve impulse.

Movement is a characteristic of all the living organisms. From the protoplasmic movement in a cell and unicellular organisms to the movement of organs in multicellular organisms, movement accounts for the various important functions in the living organisms. In this chapter students will learn about locomotion, joints , muscle,muscle contraction and skeletal system.

Digestion is the process of breaking large, insoluble food molecules into smaller molecules for absorption into the bloodstream. This process involves the use of many digestive fluids and enzymes such as saliva, mucus, bile and hydrochloric acid, among others. In this chapter we will discuss absorption of digested products,alimentary canal and digestive glands.
