Transpiration

Question 1

What is the transpiration

Answer 1

The excess of water is lost from the aerial parts of plants in the form of water vapors.

Question 2

What are the types of transpiration

Answer 2

Stomatal transpiration, Cuticular transpiration and Lenticular transpiration

Question 3

What is stomatal transpiration

Answer 3

Stomatal transpiration is the process through which plants release 80-90% of their water as vapor, occurring only during daylight when stomata open in the presence of sunlight and close in darkness.

Question 4

What is Cuticular transpiration

Answer 4

Cuticular transpiration is the day-night water release through the thin cuticle layer of leaves and stems, resulting in 5-10% water vapor loss.

Question 5

What is Lenticular transpiration

Answer 5

Lenticular transpiration is the release of water vapor through lenticels, small openings in the corky tissue of stems and twigs, with only 0.1% water loss occurring in this process.

Question 6

What are the factors that affect transpiration

Answer 6

Temperature, Light intensity, Wind and Humidity

Question 7

The importance of transpiration

Answer 7

It cools the plant
It helps the plant to take up nutrients
It allows gas exchange
It regulate the leaf as well as other parts temperature

Question 8

Reflex arc

Answer 8

The skeletal reflex arc coordinates rapid and involuntary muscle responses through sensory neurons, spinal cord interneurons, and motor neurons.
