In plant cells
General KnowledgeBiology
- ANucleus does not need a membrane but chloroplasts are surrounded by their own membrane.
- BNucleus and chloroplasts are surrounded separately by their own membrane.
- CNucleus is surrounded by membrane but chloroplasts do not need membrane.
- DBoth nucleus and chloroplasts are not surrounded by any membrane.
Explanation
In plant cells the nucleus is enclosed by a double nuclear membrane with pores. Chloroplasts are also membrane-bound organelles, surrounded by a double membrane enclosing the stroma and thylakoids. Both therefore have their own surrounding membranes. The correct statement is that nucleus and chloroplasts are each separately surrounded by membrane.
