Biology Question on Strategies For Enhancement in Food Production
A protoplast is a cell
A
undergoing division
B
without cell wall
C
without plasma membrane
D
without nucleus.
Answer
without cell wall
Explanation
Solution
A protoplast is a cell without a cell wall that is composed of cytoplasm, plasma membrane, and cell organelles.
- The cell wall is removed by the action of enzymes.
- Cellulase enzymes digest cellulose present in plant cell walls.
- Pectinase enzymes break down the cells that hold pectin together.
- Once, the cell wall is removed, the protoplast becomes spherical in shape.
Hence, option B) without cell wall is the correct answer.
