(b) What happens if conducting tubes of circulatory system develops a leak? State in brief, how could this be avoided? (c) How opening and closing of stomata takes place? -Biology

Last Answer : (a) The breathing cycle involves inhalation and exhalation of air due to alternate expansion and contraction of thoracic cavity. Thus it is a rhythmic process. But exchange of gases is a continuous process ... pore opens up. When water moves out the guard cells shrinks and the stomatal pore closes.

Leaves of many grasses are capable of folding and unfolding because (1) their mesophyll is not differentiated into palisade and spongy parenchyma (2) they have stomata on both sides of the leaf (3) they have high levels of silica (4) they have specialised bulliform cells

Description : Leaves of many grasses are capable of folding and unfolding because (1) their mesophyll is not differentiated into palisade and spongy parenchyma (2) they have stomata on both sides of the leaf (3) they have high levels of silica (4) they have specialised bulliform cells

Last Answer : (4) they have specialised bulli-form cells Explanation: Bulliform cells are large, bubbleshaped epidermal cells that occur in groups on the upper surface of the leaves of many grasses. These cells, by their turgor changes, cause rolling and unrolling of the leaves thus regulating water loss.
