(b) The process by which the intact plant loses water in the form of droplets (c) An instrument used to find the rate of transpiration (d) A plant in which the stomata are sunken (e) The apparatus to record the rate of transpiration in a cut shoot. Photosynthesis ceases when leaves wilt, mainly because. ... sunken stomata D) a rainstorm E) a thicker cuticle. These needle-like leaves have sunken stomata and a smaller surface area: two attributes that aid in reducing water loss. Sunken stomata are like normal stomata except they are literally sunken into the leaf a few micrometres. The loss of water as water vapour from the aerial parts of a plant is known as (a)evaporation (b) perspiration (f) Any two parts of a leaf which allow transpiration. A) Without transpiration, the plant will be water deficient. Number of Stomata (Stomatal Frequency): The number of stomata in a definite area of leaf varies from plant to plant. B. CO2 dissolved in the plasma. Stomata: action and regulation. Which of the following is not true of primary and secondary growth?
