Question

Identify the components labelled A, B, C, D, E and F in the diagram below from the list (i) to (vi) given along with:-


Components :
(i) SER (ii) Ribosome (iii) Nucleus
(iv) Cytoplasm (v) Nuclear pore (vi) RER
The correct components are :-

• A. A –v, B-i, C-vi, D-iv, E-ii, F-iii
• B. A-i, B-iii, C-ii, D-vi, E-v, F-iv
• C. A-iii, B-vi, C-i, D-ii, E-iv, F-v
• D. A-iii, B-i, C-ii, D-vi, E-v, F-iv

Answer 1

The correct option is C A-iii, B-vi, C-i, D-ii, E-iv, F-v

Nucleus is a double membrane-bound organelle. Nuclear membrane is perforated by apertures known as nuclear pore.
Ribosomes present on endoplasmic reticulum is known as rough endoplasmic reticulum, whereas when ribosomes are not present on endoplasmic reticulum, then it is known as smooth endoplasmic reticulum.
So, the correct sequence is -
A- Nucleus
B-RER
C-SER
D-Ribosome
E-Cytoplasm
F-Nuclear pore
Therefore, the correct answer si option 'c'.
