What is the best definition of transpiration?
Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves.
An example of transpiration is when a plant absorbs water in its roots.
YourDictionary definition and usage example..
What is transpiration and its importance?
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism.
What is transpiration and its functions?
The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface. This is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis.
What is the role of transpiration in transportation explain with diagram?
The evaporation of water from the leaf surface, known as transpiration also produces a pulling force that causes the water to move upwards. The transpiration of water and dissolved mineral salts, from the root to the stem, leaves, flowers and other parts of the plants takes place through the xylem.
Why is transpiration important for humans?
Transpiration is important to humans as it accounts for the total evapotranspiration on earth. Transpiration is also part of the water cycle and…
What is transpiration rate?
The rate at which transpiration occurs refers to the amount of water lost by plants over a given time period. Plants regulate the rate of transpiration by opening and closing of stomata (Figure 5.14).
What are the factors that affect transpiration?
Factors affecting transpirationFactorChange in factor that increases transpiration rateTemperatureIncreaseHumidityDecreaseAir movementIncreaseLight intensityIncrease
What are the names of the two types of cells needed to make the phloem tissue?
Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids.
Why is translocation important?
Answer: Translocation in plants occurs by means of the vascular tissue known as phloem. Translocation is necessary because without it, the food prepared by the leaves cannot reach other parts of the plant. In plants, the synthesis of sugars takes place in the leaves by the process of photosynthesis.
What is transpiration and types of transpiration?
There are three types of transpiration, the process in which water is lost from plants in the form of gas or vapor: stomatal, cuticular, and lenticular. … Stomatal transpiration – Among the three types of transpiration, this is the most dominant being responsible for most of the water loss in plants.
What are two advantages of transpiration?
(i) It helps in absorption and upward movement of water and minerals from roots to the leaves. (ii) It regulates the temperature. (iii) Loss of water from the leaves increases concentration of the cell sap, thereby augmenting the osmotic pressure.
What are the three functions of transpiration?
Answertransporting minerals from the soil to the other parts of the plant.for maintaining the temp. of the plant.maintaining turgor pressure.
How is water transported at night in plants?
At night, when stomata shut and transpiration stops, the water is held in the stem and leaf by the adhesion of water to the cell walls of the xylem vessels and tracheids, and the cohesion of water molecules to each other.
What is the role of transportation in transporting water and minerals in plants?
Xylem- Fundamental tissue for transportation of water In plants, minerals and water are transported through the xylem cells from soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts.
What is transpiration class 10th?
Transpiration is the loss of water in the form of water vapours from the aerial surface of the plants. Stomatal transpiration, cuticular transpiration and lenticular transpiration are the modes of transpiration.
What is the function of xylem?
Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water‐conducting function of xylem is one of the major distinguishing features of vascular plants.
What is the process of translocation?
Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.
What is the role of transpiration in transportation?
Role of transpiration in plants It helps it to transport water and minerals towards the leaves from the roots in the upward direction against the gravitational pull. … Continuous evaporation from stomata of leaves creates suction which pulls up water through xylem vessels .
What is the definition for transpiration?
an action or instance of transpiring. Botany. the passage of water through a plant from the roots through the vascular system to the atmosphere.
What are some differences between transpiration and translocation?
The difference between transpiration and translocation are as follows : 1) Transpiration is the process of loss of excess water from the plants while Translocation is the transport of of prepared food from to different parts of the plant.
What is the relationship between transpiration and water transportation?
Mechanism Driving Water Movement in Plants The bulk of water absorbed and transported through plants is moved by negative pressure generated by the evaporation of water from the leaves (i.e., transpiration) — this process is commonly referred to as the Cohesion-Tension (C-T) mechanism.
What are advantages of transpiration?
It helps in the absorption and distribution of water in plants. It helps in the absorption and transport of mineral salts in plants. It provides coolness to the plant body. Osmotic balance of the cell is maintained by the process of transpiration.
