Q. Explain the term Guttation?​

Answer 1

Answer:

• Guttation is the phenomenon in which water is removed in liquid phase (exudation of water) through intact plants parts.

• Guttation can be frequently seen when atmosphere is humid, transpiration is low and active absorption of water is more.

• This active absorption of water develops pressure in root, i.e. root pressure.

• Guttation is often observed early in the morning when excess of water collects in the form of droplets.

• These droplets are formed at the special openings of veins near the tip of grass blades and leaves of many herbaceous plants.

• In ferns, guttation occurs through special glands called hydathodes.

• Water exuded by guttation contains salts.

Answer 2

Answer:

Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of a small herbacious plant. ... Plants have hydathodes at the end of the veins, through which this excess water is lost in the form of droplets. It takes place mostly in small plants like banana, rose, etc. ..
