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

What do you understand about guttation?

• The water loss from plants in liquid form through stoma on the surface of the leaves.

• The water loss from plants in liquid form through hydathodes(opening) at the edge of the leaves.

• The water loss from plants in the form of water vapour through hydathodes(opening) at the edge of the leaves.

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

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

Remember when you put the celery in the water? What happened to the water level by the next day?
