AP and TS 10th class biology important questions 2020 - chapter-03 (TRANSPORTATION)

         AP / TS SSC BIOLOGY IMPORTANT                         QUESTIONS FOR CLASS 10   -   CHAPTER 3 1. What is root pressure? How it is useful to the plants?  Root pressure is osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. Root pressure develops due to the absorption of water by roots and pushes the water upwards by a few meters and is enough to supply water to leaves in small plants and small trees. Root pressure provides a modest push in the overall process of water transport.  They obviously do not play a major role in water movements up tall trees. The greatest contribution of root pressure may be to re-establish the continuous chains of water molecules in the xylem. Root pressure does not account for the majority of water transport. 2. Explain an experiment to understand root pressure. Root pressure AIM: To understand the root pressure. Materials required: Potted plant, glass tube Procedure:  A potted plant is wat

AP SSC 10th class biology important questions (1st lesson) with answers.

AP SSC important questions  Biology- 1st lesson 1.   Explain the structure chloroplast with a neatly labelled diagram. Structure of chloroplast 1) The chloroplast is a membranous structure, consisting of 3 membranes. 2) The intermediary fluid filled portion called as stroma is responsible for enzymatic reactions leading to the synthesis of glucose, which in turn join together to for starch. 3) Typical chloroplasts are disc shaped and are filled with colourless area called stroma. 4) They are covered by two membranes. 5) Stacks of thylakoid membranes are located in the stroma and are connected by stroma lamella. 6) Due to the presence of chlorophyll, chloroplasts are green. 7) The chlorophyll pigment is fat soluble and is located in the lipid part of the thylakoid membrane. 8) Chlorophyll is organized to form the reaction centres called photosystem-1 and photosystem-11. 2. Write the difference between light reaction and dark reaction.                   Ligh
