Question

Consider the following statements
(a) Lysosomes keep the cells clean by digesting foreign materials.
(b) Ribosomes are present in eukaryotic cells only.
(c) The ER (endoplasmic reticulum) functions both as passageway for intracellular transport and as a manufacturing surface.
Which of the above statements are correct?

• A. (a) and (b)
• B. (b) and (c)
• C. (a) and (c)
• D. None of the above

Answer 1

The correct option is C (a) and (c)

The ribosome is responsible for the synthesis of proteins. It is found in all cells, both; eukaryotic as well as prokaryotic. Lysosomes are the small vesicles containing hydrolytic enzymes for the digestion foreign particles, cell debris and dead or weak cellular component, it cleans the cell by digesting unwanted substance in the cell. The endoplasmic reticulum is the membranous network in the cytoplasm. It involves the formation and transportation of materials like proteins, lipids steroids etc. Thus, the correct answer is option C.
