State true of false for the given statements. During transpiration… For respiration, sunlight and chlorophyll are needed.3. (f) Transpiration cools the plant when it is hot outside. Stomata: 1. The amount of water received by the leaves are used for the photosynthesis and the excess amount of water is released into the atmosphere in the form of vapours through the … ... through which phloem transport takes place. Transpiration: Transpiration is the technical term for the evaporation of water from plants. 3. Leaf … This is called the cohesion–tension theory of sap ascent. (a) Both A and R are true … Stomatal transpiration – 80-90 per cent water loss . Answer 6 (d) transpiration. Transpiration—the loss of water vapor to the atmosphere through stomata—is a passive process, meaning that metabolic energy in the form of ATP is not required for water movement.The energy driving transpiration is the difference in energy between the water in the soil and the water in the atmosphere. Ans :- True (g) During transpiration, the leaves lose more water from their upper surface. This portal is designed to support Students and Teachers of Central Board of Secondary Education. Guttation takes place through (a) stomata (b) lenticels (c) lower epidermis of leaves (d) hydathodes. 3. The insides of the plant closes up so it can travel. True or False: Roots can concentrate nutrients that … 1. Answer: True. Transpiration: The extra water comes out of the leaves through stomata in the form of vapour. Question 1. Transpiration is the loss of water from the aerial parts of the plant. Question 7. Answer to: What effect does wind have on transpiration? They pull water from the stem, which in turn pulls water from the roots. Answer:Explanation:Hii..Transpiration is a necessary evil because..1.As transpiration helps in cooling of surrounding atmosphere by loss of … More transpiration occurs from the under surface of a leaf.) True or False. In old stems, gaseous exchange takes place through the stomata.4. The loss of water from the aerial parts of a plant is called transpiration. True. answer choices . Water is drawn up through the roots and used for cellular processes, such as photosynthesis. IV. The loss of water as water vapour from the aerial parts of a plant is known as (a)evaporation (b) perspiration (c) guttation (d) transpiration.
