Transpiration | MCQs

Explanation

• In plants, water and minerals are transported from the roots to the leaves through the xylem.
• A type of vascular tissue.

Explanation

Transpiration is the process of removal of excess water from the plants through tiny openings in leaves known as stomata.

Explanation

• During photosynthesis, plants release oxygen (O2) as a byproduct.
• Which is transported out of the leaf into the air through tiny openings called stomata.
• This process is called transpiration.

Explanation

Guard cells regulate the opening and closing of stomata, controlling gas exchange and transpiration.

They surround the stomata and change shape in response to environmental conditions, opening or closing the stomata as needed.

Explanation

Transpiration is the process by which plants lose internal water in the form of water vapor through aerial parts such as leaves, stems, and flowers.

This process occurs mainly through small openings called stomata.

Explanation

• Transpiration is the process by which water is transported through the plant and evaporates from the aerial parts.
• Such as leaves, stems, and flowers, primarily through small openings called stomata.

Explanation

• Stomata are small openings on the surface of leaves that allow for gas exchange.
• Including the release of water vapor (transpiration) and the entry of carbon dioxide.
• This process is essential for photosynthesis and regulation of water balance in plants.
