Often asked: What Does Transpiration Mean In Science?

What is transpiration in plants?

The water eventually is released to the atmosphere as vapor via the plant’s stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.

What is transpiration and its function?

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 transpiration Class 9?

This process of elimination of excess water from the plant body is known as transpiration. It is generally the evaporation of water from the surface of the leaves. During the process of transpiration, water molecules in the plant tissues are removed from the aerial parts of the plants.

What is transpiration and its types?

Definition of Transpiration: Transpiration is the process of water movement through a plant and its evaporation from aerial parts especially from leaves. Its Type: Cuticular Transpiration. Lenticular Transpiration. Stomatal Transpiration.

What is transpiration explain?

Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.

What is transpiration in simple words?

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 why is it important?

Transpiration is the process in which plant roots absorb water and then release the water in the form of vapour through the leaves. Transpiration is an important factor in the water cycle as it is one of the major sources of water into the atmosphere.

What are two functions of transpiration?

Transpiration – The loss of excess water from plant through stomata present in their leaves is called Transpiration. Two functions – (1) Exerts a cooling effect on plants. (2) Uptake of minerals salts and maintenance of water balance.

What are the steps of transpiration?

1- Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

What is translocation class 10th?

Transport of soluble product of photosynthesis or food from leaves to other parts of plants is called translocation. For translocation, food molecules enter the part of the phloem called the sieve tubes where they can be transported upwards or downwards to all the parts of the plant including roots.

What is the importance of transpiration?

Transpiration plays an important role in the existence of plants. As discussed, Transpiration plays a significant role by removing excess water from the aerial parts of the plants. The Significance of Transpiration in plants includes: Keeps the cell turgid.

Which is the most common type of transpiration?

Types of Transpiration:

  • Stomatal Transpiration: The loss of water through stomata is called stomatal transpiration. It is the most common type of transpiration from plants.
  • Cuticular Transpiration: ADVERTISEMENTS:
  • Lenticular Transpiration:

Which type of transpiration is more common?

Such type of transpiration is called as stomatal transpiration. It constitutes about 50-97% of the total transpiration. It occurs through the stomata. Thus, the correct answer is option A.

What are the two main types of plant transpiration?

There are two type of transpiration: lot jar transpiration and lenticular transpiration. the transpiration which takes place through the lea’ es is called foliar transpiration. The foliar transpiration may be stomata’ transpiration or cuticular transpiration.
