Question

Answer

Ab dekho khud aap hi scientists sab kuch na kuch din bhar karte rahte hai unka mind OFF nahi hota. Islia unhone iss process ka nam TRANSPIRATION rakh dia. Aur bola aaj se plants water loss karenge stomata se to unhe TRANSPIRATION bola jaega

Answer

Option B is the correct answer because see:
Respiration is a process in which living organisms produces energy, with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of a plant.

Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves.

The passage of material through a semi-permeable membrane from a region of higher to a region of lower concentration, especially the passage of water through a cell membrane into the surrounding medium, is called exosmosis.

Answer

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.Here loss of water takes place in the form of water vapour.Hence correct aswer is option (b)

Answer

The correct answer is option 'B' - Transpiration.

Transpiration is the process by which plants lose water in the form of water vapor through small openings called stomata present on the surface of leaves, stems, and other aerial parts of the plant. This process is essential for the survival of plants as it helps in the absorption of water and minerals from the roots, and also aids in the regulation of temperature and movement of nutrients within the plant.

Here is a detailed explanation of the process of transpiration:

1. Structure of Stomata:
Stomata are tiny openings present on the surface of leaves and other aerial parts of the plant. Each stoma is surrounded by two specialized cells called guard cells. These guard cells control the opening and closing of the stomata, thereby regulating the process of transpiration.

2. Process of Transpiration:
During transpiration, water from the plant's internal tissues evaporates and exits the plant through the stomata. The water vapor then diffuses into the surrounding air. Transpiration primarily occurs through the lower surface of leaves, as they have a higher number of stomata compared to the upper surface.

3. Factors Affecting Transpiration:
Several factors influence the rate of transpiration in plants:

- Temperature: Higher temperatures increase the rate of transpiration as they increase the evaporation of water from the plant's surface.
- Humidity: Higher humidity decreases the rate of transpiration as the air surrounding the plant is already saturated with moisture, reducing the gradient for water vapor diffusion.
- Wind: Increased air movement enhances transpiration by removing the water vapor from the vicinity of the stomata, maintaining a steep concentration gradient.
- Light intensity: Higher light intensity leads to increased transpiration as it stimulates the opening of stomata for the exchange of gases required for photosynthesis.

4. Significance of Transpiration:
Transpiration plays several vital roles in plants:

- Water absorption: Transpiration creates a suction force that helps in the upward movement of water and minerals from the roots to the aerial parts of the plant.
- Cooling effect: As water evaporates from the plant's surface, it cools down the plant, preventing overheating.
- Nutrient transport: Transpiration helps in the transport of essential nutrients and minerals within the plant.
- Turgor pressure: Transpiration maintains the turgor pressure in plant cells, which is necessary for their structure and support.

In conclusion, transpiration is the process by which plants lose water in the form of water vapor through stomata. It is a crucial process for the survival and functioning of plants.

Answer

Answer

Option [b] becoz----->

Transpiration is the loss of water in the form of vapour, from stomata and lenticels .It is signified by generating the pulling force responsible for the ascent of sap, surface cooling of leaves and minerals dissolved in water enter plant body due to water replacing the subsequent gaps created due to evaporation.

Answer

Correct option is B because transpiration is a process by which plant losses excess of water in the form of water vapour through stomata. In desert plants to prevent excess of transpiration there is a layer of cutin which is a waxy coating in outside of the plant body.
