How waxy cuticle involved in photosynthesis

WebFour major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed (Fig. 1), a gametangium that produces haploid cells, and apical meristem tissue involved in growth. The evolution of a waxy cuticle (Fig. 2) and a cell wall with lignin also contributed to the success of land ... WebHow is a leaf adapted for photosynthesis? Leaves have a large surface area so more light hits them. The upper epidermis of the leaf is transparent, allowing light to enter the leaf. The palisade cells contain many chloroplasts which allow light to be converted into energy by the leaf. The leaf also has air spaces which allow better diffusion of ...

WebLower Epidermis: A protective layer of cells. The lower epidermis produces a waxy cuticle too in some plant species. The lower epidermis contains pores called stomata that allow carbon dioxide and oxygen to move in and out of the plant respectively. Stomata: Tiny pores (small holes) surrounded by a pair of sausage shaped guard cells. WebStomata are small holes on the underside of the leaf that let gases diffuse in and out (the singular of stomata is stoma). This is important part of the plant during photosynthesis as Carbon dioxide is absorbed, Oxygen is released and water vapour is diffused out. 6CO2 + 6H2O → C6H12O6 +6O2 Carbon dioxide + Water (+ light energy) → Glucose…
