Question

Match the columns and find the correct option : Column I Column II A) Nuclear pore i) Packaging of materials B) Nucleolus ii) Transport of materials against concentration gradient C) Golgi complexes iii) RNA synthesis D) Tonoplast iv) Transport of proteins and RNA

• A. A(iii), B(iv), C(ii), D(i)
• B. A(iv), B(iii), C(ii), D(i)
• C. A(iv), B(iii), C(i), D(ii)
• D. A(iv), B(i), C(ii), D(iii)

Answer 1

Answer: (C)

A(iv), B(iii), C(i), D(ii)

Answer 2

The question requires matching cell structures with their functions:

• Nuclear pores facilitate the transport of proteins and RNA between the nucleus and cytoplasm.

• The nucleolus is the primary site for ribosomal RNA (rRNA) synthesis.

• Golgi complexes are involved in packaging materials (proteins, lipids) into vesicles.

• The tonoplast, the vacuolar membrane, actively transports substances against their concentration gradient.

Therefore, the correct matching is:

• A (Nuclear pore) - (iv) Transport of proteins and RNA
• B (Nucleolus) - (iii) RNA synthesis
• C (Golgi complexes) - (i) Packaging of materials
• D (Tonoplast) - (ii) Transport of materials against concentration gradient
