Transpiration

Why plants become wilt?

• Less water evaporate from the plants

• The plant loss excessive amount of water through transpiration

• The stomata of the plants are closed

• The weather are cool.

Define transpiration.

• Loss of water from plants

• Loss of water through stoma on the leaves

• Process of water loss in the form of water vapour from the surface of the leaves through evaporation

• Process of water loss in the form of liquid from the surface of the leaves through evaporation

Transpiration process in plants occur

• at night

• during daytime

The function of transpiration is to transport _______ and ____________ from the roots to the leaves

• water, mineral salts

• food, nutrients

• water, food

What is the function of waxy cuticle on the leaves surface?

• Provide water for the plant through the leaves

• Reduce the loss of water from the plants by evaporation

• Protect the plants from danger

If the surrounding temperature become higher, plants will loss water _______ through the stoma

• faster

• slower

The faster the movement of air, the ____the rate of transpiration.

• slower

• faster

The rate of transpiration in plants will be lower/slower when the light intensity is ______

• higher

• lower

How do plants with thick waxy cuticles reduce water loss through transpiration?

• Increasing the surface area of the leaves to allow more water to escape

• Opening stomata wider to release excess water

• Reducing the amount of water absorbed from the soil

• Creating a barrier that prevents water from escaping

Transpiration is the:

• process by which plants release water vapor into the ground.

• Process by which plants release water vapor into the air.

• Process by which plants obtain food from soil.

• Process by which water is created.
