• A. Is an enclosure of glass in which plants are kept to

• B. Is that “body” which allows the short-wavelength incoming solar radiation to enter in but does not allow long-wavelength outgoing infra-red radiations to escape out
• C. Both (a) and (b)
• D. Neither (a) nor (b)

Answer 1

The correct option is C

Both (a) and (b)

The correct option is C.

Explanation of the correct answer:

Greenhouse:

1. The greenhouse is an enclosure or building that is made up of glass walls and a roof in which plants are grown.
2. The purpose of a greenhouse is to magnify the sunlight and protect the plants from the outer cold air.
3. During the magnification of sunlight, it allows the entry of rays with shorter wavelengths but does not allow the escape of rays with longer wavelengths i.e it traps the infra-red waves that result in making the inner temperature warmer.

Final answer: A green house
