Free Photosynthesis In Higher Plants (Daily Quiz: 3) NEET Biology Questions & Answers with Detailed Explanation & Full Review

Free Photosynthesis In Higher Plants (Daily Quiz: 3) Time:

Question-1

Which of the following cells of $C_4$ plants are prominently loaded with starch?

(a)

(b)

(c)

(d)


Question-2

A process that makes important difference between $C_{3}$ and $C_{4}$plants is :

(a)

(b)

(c)

(d)

Explanation:

Answer: (d)

Photorespiration is absent is $C_{4}$ plants. Photorespiration does not produce energy or reducing power. Rather, it consumes energy. There is 25% loss of fixed C$O_{2}$.Therefore, photorespiration is a highly wasteful process. This happens only in case of $C_{3}$ plants.


Question-3

Where does the primary photochemical reaction occur in chloroplast/Where does the light reaction of photosynthesis takes place?

(a)

(b)

(c)

(d)


Question-4

Carbon refixation in $C_{4}$ plants occurs in chloroplasts of –

(a)

(b)

(c)

(d)

Explanation:

Answer: (c)

Carbon refixation in $C_{4}$ plants occurs in chloroplasts of bundle sheath cells.


Question-5

Which part of the plant do not perform photosynthesis?

(a)

(b)

(c)

(d)

Explanation:

Answer: (d)

Photosynthesis occurs particularly in specialized cell called mesophyll cells. These cells contain chloroplast, which is the actual sites for photosynthesis. The cactus stem and guard cell of stomata contain chloroplasts, so they can manufacture food by photosynthesis. The epidermal cells do not contain chloroplasts, so they do not perform photosynthesis.
