Question

Refer to the given dichotomous key and select the correct option regarding cell organelles L - O.

I. (a) Cell organelle bounded by double-membrane - Go to II
(b) Cell organelle bounded by a single membrane - Go to III
II. (a) Directs cell growth and controls its activities - $L$
(b) Provides colour to flowers and fruits - $M$
III. (a) Removes dead cells and digests foreign material - $N$
(b) Carries out some oxidative reactions in a cell - $O$

• A. L could be mitochondria whereas M could be chloroplast
• B. M could be chromoplast whereas N could be golgi apparatus
• C. L could be nucleus whereas O could be peroxisome
• D. M could be leucoplast whereas N could be vacuole

Answer 1

The correct option is C L could be nucleus whereas O could be peroxisome

L is a nucleus that is double layered and directs cell growth and its activities. M is a chromoplast which gives colour to fruits. N is lysosome which digest foreign materials and O is peroxisome that has hydrogen peroxide that carries out oxidative reactions.

So the correct answer is "L could be nucleus whereas O could be peroxisome".
