plant photosynthesis

. Without the constant supply of water the plant cannot carry on any of its physiological activities such as photosynthesis, respiration and growth. Obviously an understanding of the manner in which plants get water is important. In this chapter we shall study the abso..

. growth is uniform and proportionate. Manufacture there own food by photosynthesis. cannot make their own food. They depend directly or indirectly on plants for their food Sense organs and nervous system absent. Well-developed nervous system. Let us study the classification of ..

. These tissues can be distinguished into 3 types parenchyma, collenchyma and sclerenchyma. Parenchyma is a simple, living, storage tissue occurring in every part of the plant body. It also takes part in photosynthesis, respiration, transpiration and secretion. Collenchyma is a ..

The plant cannot carry out photosynthesis in the absence of light and all the starch present in the leaves is used up. Thus the leaves are destarche..

Energy is the capacity to do work. Solar energy is transformed into chemical energy by the process of photosynthesis, and is stored in plant tissue and then transformed into mechanical and heat forms during metabolic activitie..
