Question

Match the items given in column A with most appropriate ones in column B. Rewrite the correct matching pairs.

Column 1	Column 2
Potometer	Hydathodes
Transpiration	Bleeding
Guttation	Water Absorption
Wilting	Water Vapor
Toddy Palm	Afternoon

Answer 1

A. Potometer III. Water Absorption

1. Potometer is a device that measures the rate of water absorption by a cut shoot.
2. In turn, it measures the rate of transpiration.

B. Transpiration IV. Water Vapor

1. Transpiration is the loss of water through stomata, lenticels, or cuticles of the plant.
2. The water is lost in the form of water vapor through these pores.

C. Guttation I. Hydathodes

1. Hydathodes are permanent pores on the edges of uninjured leaves that favor guttation.
2. Water is lost as droplets during guttation.

D. Wilting V. Afternoon

1. During the afternoon on a bright sunny day, the rate of transpiration exceeds the rate of absorption of water by the roots.
2. This causes wilting of the plant.

E. Toddy Palm II. Bleeding

1. Bleeding is the oozing out of sap or watery solution from the cut or injured part of a plant.
2. Bleeding from plants like Toddy Palm is commercially exploited.
