Answers
Answer:
4.The process of synthesis of food in green plants is called photosynthesis. This process takes place in the cells containing the green pigment chlorophyll. ... During photosynthesis, chlorophyll containing cells of leaves, in the presence of sunlight, use carbon dioxide and water to synthesise carbohydrates.
5.Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts. ... This pair effects the final function of chlorophylls, charge separation, leading to biosynthesis.
6.For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. ... During photosynthesis, the oxygen gas produces goes out through the leaves of the stomatal pores
7.Plants absorb water and minerals by the roots. ... The vascular tissue for the transport of water and nutrients in the plant is called the xylem. The xylem forms a continuous network of channels that connects roots to the leaves through the stem and branches and thus transports water to the entire plant .
