Maintaining plants at cool or high temperatures causes, along with the changes in photosynthesis described above, increase in their resistance to otherwise lethal temperatures (frost and high temperature). This is hardening. WebThe adaptations of leaf for photosynthesis are as follows: (a) Leaves provide large surface area for maximum light absorption. Which help them to absorb more photons. (b) Leaves are arranged at right angles to the light source in a way that causes overlapping for absorption of more light. (c) The extensive network of veins enables quick ...

WebPhotosynthesis is the process of taking carbon dioxide, water, and light into the chloroplasts of a plant and then using them together to produce glucose. The glucose then serves as a food for the plant. Oxygen, which goes off into the atmosphere from the plant, is also produced by photosynthesis as a by-product. WebLeaves of Dicotyledonous Plants. In order to carry out photosynthesis, plants must have an adequate supply of carbon dioxide; There is only roughly 0.036% CO 2 in the atmosphere, so efficient gas exchange is necessary; Leaves have evolved adaptations to aid the uptake of carbon dioxide; Structure of a leaf: Waterproof cuticle massena central school staff
