Description : What is the function of the stomata?
Last Answer : A: Stomata are tiny pores found on the leaves of plants that regulate gas exchange, allowing carbon dioxide to enter the leaf for photosynthesis while also allowing oxygen and water vapor to exit.

Last Answer : Answer.(a) (i) Gaseous exchanges between plant and the atmosphere. (ii) Plant loses water through stomata which helps in movement of minerals from soil to leaves. (b) Raw materials for ... getting average light of 10-12 hrs a day. The chemical equation for photosynthesis is as follows:
Description : (a) Leaves of a healthy potted plant were coated with vaseline to block the stomata. Will this plant remain healthy for long? State three reasons for your answer. (b) State any two differences between autotrophic nutrition and heterotrophic nutrition. -Biology
Last Answer : (a) No, this plant will not remain healthy for long. The plant will begin to die because (i) Gaseous exchange will not take place. (ii) No absorption of C02, hence no photosynthesis. (iii) Transpiration will not occur; hence no transportation of water.
Description : (a) “The breathing cycle is rhythmic whereas exchange of gases is a continuous process”. Justify this statement. (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.
Description : (a) Draw a diagram to show open stomatal pore and label on it: (i) guard cells (ii) chloroplast (b) State two functions of stomata. (c) How do guard cells regulate the opening and closing of stomatal pore? -Biology
Last Answer : (a) (b) Two functions of stomata are: (i) Exchange of gases between the plant and the atmosphere takes place through stomata. (ii)Transpiration in plants takes place through stomata. ( ... through these stomata, the plant closes these pores when it does not require carbon dioxide for photosynthesis.

Last Answer : transpiration
Description : Stomata in bryophytes are present in the of: (a) Capsule (b) Leaf (c) Stem (d) Seta
Last Answer : Ans. ((a))
Description : Stomata that is present on only under surface of leaf.
Last Answer : Ans. Apple and Mulberry type
Description : The types of stomata mostly present on lower surface of leaves
Last Answer : Ans. Potato type
Description : Opening and closing of stomata are due to its
Last Answer : Ans. Turgidity and faccidity
Description : Stomata is found mainly on
Last Answer : Ans. Lower surface of leaves
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.
Description : Name the tiny pores present on the surface of leaves in plants. (1) Pits (2) Stomata (3) Trichomes (4) Hydathodes
Last Answer : (2) Stomata Explanation: Stomata are pores in the surface of the leaf. The pore is surrounded by two guard cells. When these two guard cells take up water, they bend and open up the pore between them.
Description : The exchange of gases takes place in the leaves through these pores for the purpose of photosynthesis. These pores are called – (1) Guard Cells (2) Stomata (3) Chloroplast (4) None of the above
Last Answer : (2) Stomata Explanation: Stomata are tiny pores present on the surface of the leaves via which exchange of gases takes place in the leaves for the purpose of photosynthesis. However, exchange of gases also occurs across the surface of stems, roots and leaves as well.
