Answer» Answer: 1 ans. A land plant may die if its roots remain water logged for a long TIME because too much water expels all the air from in-between the soil particles. ... Under these conditions the roots will respire anaerobically producing alcohol which may kill the plant. 2 ans. There are two types of Respiration: AEROBIC Respiration — Takes place in the presence of oxygen. Anaerobic Respiration –Takes place in the absence of oxygen. 3 ans .a) Respiration in roots: The roots of a plant take the oxygen required for respiration from the air present in-between the soil particles by the process of DIFFUSION. ... (c) Respiration in LEAVES: The leaves of a plant has tiny PORES called stomata through which the exchange of respiratory gases takes place by diffusion. |
