Plants have special pores called stomata to allow passage of gases into and out of the plant leaf. This is the site where carbon dioxide is taken into the leaf and oxygen is released from the leaf. Water can also exit the leaf through these pores.

The stomata pores are surrounded on both sides by jellybean shaped cells called guard cells. These cells expand or contract to open or close the stomata. Guard cells also close when the plant is dehydrated or in dry weather to keep more water in the plant.

The number of stomata on the underside of a leaf can tell a lot about a plant. Usually, a high concentration of stomata indicates fast growth and a wet climate. Lower concentrations of stomata indicate lower rates of photosynthesis and growth and are adaptations for dry weather.

What could you ask after seeing the video?
Where is the water coming from?

With the information you have, what is your hypothesis?This is done by yourself.

Predict what you will find on the underside of the leaf.
