D. Ribosome factory	iv. Nucleolus

• A. A-ii, B- iv, C- i, D- iii
• B. A-ii, B- iii, C- i, D- iv
• C. A-i, B- iv, C- ii, D- iii
• D. A-i, B- ii, C- iii, D- iv

Answer 1

The correct option is B A-ii, B- iii, C- i, D- iv

A. Endoplasmic reticulum forms the system of membranes in the cytoplasmic space of a eukaryotic cell.

B. Ribosomes are the membraneless cell organelles that are present on the surface of ER, inside mitochondria and chloroplast, so called organelle within an organelle.

C. Chloroplast is known as the kitchen of the cell, as it helps in the formation of carbohydrates by photosynthesis.

D. Nucleolus is the site where rRNAs are synthesised and ribosomal biogenesis takes place, so they are called ribosomal factories of the cell.
