Transpiration in plants involves all of the following except: a) Adhesion of water molecules to cell walls b) Cohesion among water molecules c) Water transport through phloem cells d) Movement of water molecules through stomata Answer: c) Water transport through phloem cells Soil Water Content: Transpiration is the discharge of water vapor from the leaves of plants into the atmosphere. Carbon cycles through the biosphere in all of the following processes EXCEPT a. photosynthesis. a.adhesion of water molecules to cellulose b.active transport of water into the stele c.evaporation of water molecules. This process also helps in ascent of sap and transportation of water and minerals to the various parts of the plants. Plants do not present great demands for gas exchange. Roots consume some amount of water from the soil and the rest evaporates in the atmosphere. (ii) The carbon dioxide which is produced during the process of respiration also gets removed through stomata. The method used by plants to get rid of excretory products are as follows: (i) The oxygen, end product of the photosynthesis gets removed through stomata. All parts of the body are connected to these tissues. 3. Such plants usually have a much thicker waxy cuticle than those growing in more moderate, well-watered environments (mesophytes). What is evapotranspiration Transpiration is important for plants because it evaporates excess water which produces a cooling effect to plants. C) photorespiration. 3. Evolution. b. transpiration. Transport in plants Xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant. Transpiration is a necessary evil in plants. d. decomposition of plants and animals. However, the plant derives some benefit from this water loss in the form of. Transpiration Is Also Linked To Other Processes In Plants, Including Photosynthesis And The Transport Of Mineral Nutrients. Plants in such environments often have a high g w v total, which leads to a somewhat higher g C O 2 total and somewhat higher rates of photosynthesis than is the case for plants with a moderate g w v total. E) transport through tracheids. temperature. Question 5. EXCEPT (A) causing the stomata to close (B) increasing the humidity of the atmosphere Biology Most Viewed Questions. A) cohesion-tension-transpiration. relative humidity. B) cohesion between water molecules. The liver is a vital organ that performs all of the following functions EXCEPT Before keeping the leaf in between the cups, anhydrous calcium chloride (CaCl 2) contained in two small vials were weighted and placed in both the cups.The ends of the cups were weighted and with corks through which two mercury manometers were connected. Transpiration in plants requires all of the following except. (E) At noon, the rate of transpiration exceeds the rate of water flow through a stem. 14) Water entering the stele of the root from the cortex must pass through the. Reverse osmosis is used in removing salts from saline water and extra purification of water. All of the following are characteristics of bacteria except one. Wind Velocity: The velocity of wind greatly affects the rate of transpiration. C) membrane potential. D) active transport. C) endodermal cytoplasm. Most of the water absorbed by the roots of a plant– as much as 99.5 per cent– is not utilized for growth or metabolic process; it is excess water, and it leaves the plant through transpiration. This is because of the process of transpiration. Explain. Transpiration, in botany, a plant’s loss of water, mainly though the stomates of leaves. B) ATP. Temperature 4.

Plants have evolved over time to adapt to their local environment and reduce transpiration. Factor # 1. It is a process that the eye cannot see, even though the amounts of moisture involved it significant. Many are photosynthetic. The process requires a driving force, viz, pressure from a pump, to push the fluid through the membrane. It is known that a large oak tree can transpire 40,000 gallons (151,000 liters) per year.

In the case of transportation in plants, the biggest constraint is water as it ends up being a limiting factor in growth. Desert plant (xerophytes) and plants that grow on other plants (epiphytes) have limited access to water. Fast moving air currents continually bring fresh, dry masses of air in contact with leaf surfaces and thus maintain a high rate of transpiration. 13) All of the following describe an important transport mechanism in plants except.
