Q
Nutrition in Plants

Question:

Mark ‘T’ if the statement is true and ‘F’ if it is false:

(i) Carbon dioxide is released during photosynthesis. (T/F)

(ii) Plants which synthesise their food are called saprotrophs. (T/F)

(iii) The product of photosynthesis is not a protein. (T/F)

(iv) Solar energy is converted into chemical energy during photosynthesis. (T/F)

Answer:

(i) Carbon dioxide is released during photosynthesis.  (False)

Correct answer: The process by which green plants make their own food from carbon dioxide and water by using sunlight energy in the presence of chlorophyll is called photosynthesis. The plant takes carbon dioxide from the air and releases oxygen gas into the atmosphere.

(ii) Plants which synthesise their food are called saprotrophs. (False)

Correct answer: The organisms which can make their food themselves are called autotrophs. The non-green plant which obtains their food from dead and decaying organic matter are called saprophytes. 

(iii) The product of photosynthesis is not a protein. (True).

(iv) Solar energy is converted into chemical energy during photosynthesis. (True)
