Chapter 10: Cell Cycle and Cell Division<\/h4>\n
All the topics like Cell cycle, mitosis, meiosis, and their significance are discussed in this chapter. Know about the characteristics of cells i.e. growth and reproduction common for all living organisms. Cells can reproduce by dividing into two and each parental cell gives rise to 2 daughter cells every time they divide. Again these newly formed cells can give rise to daughter cells and gives rise to a new cell population.<\/p>\n

<\/p>\n
Chapter 11: Transport in Plants<\/h4>\n
Class 11 Students will know the topics Means of Transport, Plant Water Relations, Long Distance Transport of Water, Transpiration, Phloem, Uptake and Transport of Mineral Nutrients, are discussed in detail. Plants obtain inorganic elements and salts from surroundings i.e. from water and soil. In higher plants, the vascular system includes the xylem and phloem responsible for translocation.<\/p>\n
Chapter 12: Mineral Nutrition<\/h4>\n
Chapter 12 deals with inorganic plant nutrition and lists the methods for the identification of elements essential for the growth and development of plants. It even elucidates information on the role of essential elements, major deficiency symptoms, mechanism of absorption of essential elements. In addition, students will become familiar with the significance and mechanism of biological nitrogen fixation.<\/p>\n
Chapter 13: Photosynthesis in Higher Plants<\/h4>\n
All Animals along with Human Beings depend on Plants for their food. Green Plants make or Synthesise Food through the process of Photosynthesis and are thus called Autotrophs. Photosynthesis is a physiochemical process that uses light energy to drive organic compounds’ synthesis. Get to know why Photosynthesis is important and how it forms the base for all known food chains on Earth. It even focuses on the structure of Photosynthetic Machinery, Various reactions that change light energy to chemical energy.<\/p>\n
Chapter 14: Respiration in Plants<\/h4>\n
In this Chapter 14 students will learn about cellular respiration, Glycolysis, Fermentation, Aerobic Respiration, Respiratory Balance Sheet, Amphibolic Pathway, Respiratory Quotient. The concept of Respiration in Plants is explained in a simple manner so that students find it easy to understand.<\/p>\n
Chapter 15: Plant Growth and Development<\/h4>\n

Coordination is the process in which two or more organs interact and complement each other’s functions. IN our body both the neural system and endocrine system function in coordination and integrate all activities in a synchronized manner. This chapter briefs you about the neural system of humans, mechanisms of neural coordination like transmission of nerve impulse, impulse conduction across a synapse and the physiology of reflex action.<\/p>\n
Chapter 22: Chemical Coordination and Integration<\/h4>\n
Since nerve fibres don’t innervate all cells of the body and cellular functions needs to be carefully monitored. This function is carried out by harmones. Neural System and Endocrine System Coordinate, Regulate the Physiological Functions in the Body.<\/p>\n
