Respiration in plant |
|
Answer» diffusion Respiration in plant by the three steps........Root _ root respiration by the diglfdusion.Stem _ stem respiration woody plants respiration by the lenticles and green stem respiration by the stomata. Leaves _ Respiration by the stomata. What is ATP and ADP function \tPlants have a branching shape, so they have quite a large surface area in comparison to their volume. Therefore, diffusion alone can supply all the cells of the plants with as much oxygen as they need for respiration.\tDiffusion occurs in the rots, stems and leaves of plants.\t\tRespiration in Roots:\t\tAir occurs in soil interspaces. Root hairs of the roots are in direct contact with them.\tOxygen of the soil air diffuses through root hair and reaches all internal cells of the root for respiration.\tCarbon dioxide produced by root cells diffuses in the opposite direction.\tIn water-logged conditions, soil air becomes deficient. In the absence of oxygen, metabolic activity of the root declines and the plant may wither.\t\tRespiration in Stems:\t\tThe stems of herbaceous plants have stomata. The oxygen from air diffuses into the stem of a herbaceous plant through stomata and reaches all the cells for respiration.\tThe carbon dioxide gas produced during respiration diffuses out into the air through the same stomata.\tIn woody stems, the bark has lenticels for gaseous exchange.\t\tRespiration in Leaves:\t\tThe leaves of a plant have tiny pores called stomata. The exchange of respiratory gases in the leaves takes place by the process of diffusion through stomata. The process of\xa0respiration in plants\xa0involves using the sugars produced during photosynthesis plus oxygen to produce energy for\xa0plant\xa0growth. ...Respiration\xa0takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic\xa0respiration |
