Which of the following is left behind when a plant cell is treated by cellulase and pectinase enzymes?
Correct answer: C. Protoplast
- A. Chloroplast
- B. Leucoplast
- C. Protoplast
- D. Chromoplast
Explanation
The protoplast refers to the living part of a plant cell, which includes the cytoplasm, nucleus, and other organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. It does not include the cell wall or any plastids. When a plant cell is treated with cellulase and pectinase enzymes, these enzymes break down the cell wall, releasing the protoplast.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
