Look at the following diagram in which a potted plant is enclosed in an airtight, transparent plastic bag.
a) What collects inside the plastic bag after some time?
b) What does this activity show?


Activity 26: Plant-in-a-Bag

Dear student,

a) Water droplets are collected in the inner surface of the plastic bag. This is because plants lose water via leaves. 
b) This activity shows transpiration by plants; i.e movement of water through the plant body starting from the roots to its evaporation via leaves or other aerial parts.

Regards
