Question

Give any 5 differences between transpiration and guttation.

Answer 1

Transpiration

• In transpiration water is lost in the form of water vapour.
• Transpired water is pure 
• Transpiration takes place through stomata, cuticle and lenticel.
• It takes place during day hours.
•  It is controlled by opening & closing by stomata (Stomatal mechanism).

Guttation

• In guttation, water is lost in the form of liquid droplets.
• The liquid coming out in guttation is not pure but it contains a number of dissolved substances like minerals, salts, sugar etc.
• Guttation takes place through hydathode.
• It takes place during the night or in the early morning.
• It is not controlled since hydathodes always remain open.
