Stomatal aperture is tightly regulated by the plant, in a system, which integrates carbon dioxide requirement with light and water stress. (c) sunken stomata (d) sunny day Solution 4: (c) sunken stomata Question 5: Guttation takes place through (a) stomata (b) lenticels (c) lower epidermis of leaves (d) hydathodes Solution 5: (d) hydathodes Question 6: The loss of water as water vapour from the acrial parts of a plant is known as (a) evaporation (b) perspiration (c) guttation Sunken stomata is found in many xerophytes because they need to reduce transpiration rate. Sunken stomata are found in plants below the plane of the epidermis. The sunken stomata of the Ficus plant helps the plant retain water. (d) Fewer stomata : In some plants, the number of stomata may be reduced. (c) sunken stomata (d) sunny day Solution:- (c) sunken stomata 5. Definition of Stomata: The stomata are minute pores which occur in the epidermis of the plants. sunken stomata can be found in xerophylic plants that lives in very hot regions like in desert with windy weather , the upper stomatal chamber contains higher RH (relative humidity) that can minimize the loss of water by transpiration.also the sunken stomata can keep the temprature relatively lower than the outer atmosphere. Transpiration has a great impact upon the metabolism of plants. 23/05/2020 7:45 pm. sunken stomata can be found in xerophylic plants that lives in very hot regions like in desert with windy weather , the upper stomatal chamber contains higher RH (relative humidity) that can minimize the loss of water by transpiration.also the sunken stomata can keep the temprature relatively lower than the outer atmosphere.
