What are the 3 functions of the Stomates?

What are the 3 functions of the Stomates?

“Functions of Stomata:

  • The main function of stomata is to open and close the pores in the leaves for an exchange of gases.
  • It allows the plant to take in carbon dioxide and give out oxygen for photosynthesis.
  • Based on the weather conditions, it closes or opens its pores to keep the moisture content developed.

What are stomata explain their function?

Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis.

What are functions of stomata Class 9?

FUNCTIONS OF STOMATA:

  • It helps in the transpiration of water, i.e., the loss of excess water from the plant.
  • Loss of water from the stomata creates an upward pull, i.e., suction pull which helps in absorption of water from the roots.
  • Stomata are responsible for the interchange of gases for respiration and 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 4 factors affect the rate of transpiration?

The light intensity, temperature, humidity, wind and water supply will all affect the transpiration rate.

What will not affect the rate of transpiration?

External factors affecting the rate of transpiration are: atmospheric humidity, temperature, light, wind velocity, atmospheric pressure and available soil water. Chlorophyll content of leaves does not directly affect rate of transpiration.

Which of the following is not a function of transpiration?

Transpiration is the process of water loss from leaves in the form of vapour. It is necessary for transporting minerals from the soil to the plant parts, cooling the plant, moving sugars and maintaining turgor pressure. Excretion of minerals does not occur through transpiration. Thus, option A is correct.

What are the functions of transpiration?

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.

Which is not a function of leaves?

Answer. Answer: (2)Conduction of water and minerals from roots to all parts of the plant….

What is the main function of plant leaves?

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.

What are the four functions of a leaf?

As one of the most important constituents of plants, leaves have several essential functions:

  • Photosynthesis.
  • Transpiration.
  • Guttation.
  • Storage.
  • Defense.
  • Conifer Leaf.
  • Microphyll Leaf.
  • Megaphyll Leaf.
