What factors affect the rate at which transpiration occurs?
The light intensity, temperature and humidity, wind, as well as the water supply, will all have an impact on the transpiration rate.
What are the factors that affect transportation?
Let us take a look at some factors that influence transportation costs.
- Fuel costs.
- The labor market for commercial drivers.
- Demand freight.
- Customer loyalty.
- Vehicle capacity.
- Government regulation.
- Geopolitical events.
- Your reputation as a merchant.
Which of these factors does not affect the rate of transpiration?
Some other factors can also influence the rate of transpiration, such as leaf area, leaf structure, and age. The rate of transpiration is not affected by the chlorophyll content of the leaves.
Which one will reduce the rate of transpiration?
When the air surrounding a leaf is dry, the diffusion of water from the leaf accelerates. The rate of transpiration is reduced when there is no breeze. If there is a breeze, humid air is removed and replaced with dry air.
Which is not responsible for Guttation in grass leaves?
Guttation may not be shown by all plants. Guttated water can be described as a dilute mixture of organic and inorganic substances. It is most common at night or in the early morning. Special structures known as hydathodes are found on the tips and margins of leaves. Guttation is caused by these special structures.
What process in plant is responsible for Guttation?
Which one of the following is the most common type of transpiration?
This type of transpiration, also known as stomatal transpiration, is called It constitutes about 50-97% of the total transpiration. It is carried out through the stomata. The correct answer is A.
What is guard cell in plants?
What are guard cells? A pair of guard cells. Each stoma is surrounded by cells on the leaf surface. Stomata are crucial because they regulate photosynthesis by absorbing CO2 from the air and also the release of water vapour to the plants during transpiration.
Which cell is called guard cell and why?
Guard cell are specialized plant cells found in the epidermis, leaves, stems, and other organs. They are responsible for controlling gas exchange. They are made in pairs and have a gap between them which forms a stomatal pores. The stomata releases oxygen (O2), a byproduct from photosynthesis.
What is the main function of guard cell?
Guard cell are located in the leaf epidermis. Two pairs of guard cells surround the stomatal pores and regulate CO2 influx from outside into the leaves to fix photosynthetic carbon. The plants’ water loss is also controlled by the transpiration to atmosphere.
What helps in closing and opening of stomata?
Two highly-specialized cells, the guard cell, surround the stomatal pores and are capable of integrating environmental and endogenous signal to control the gas exchange and the stomatal aperture.
How does the stomata function?
Stomata serve two primary functions. They allow for gas exchange, which allows for carbon dioxide (CO2) to enter and oxygen (O2) to be released. Another function is to regulate water movement via transpiration.
