In plant cells
Nucleus and chloroplasts are surrounded separately by their own membrane.
Option 2: Nucleus and chloroplasts are surrounded separately by their own membrane.
1. Structure of the Nucleus
The nucleus is a membrane-bound organelle found in eukaryotic cells, including plant cells.
It is surrounded by a distinct, double-layered membrane known as the nuclear envelope or nuclear membrane.
2. Structure of Chloroplasts
Chloroplasts are the sites of photosynthesis in plant cells.
Like the nucleus, a chloroplast is also a double-membrane-bound organelle, possessing both an outer membrane and an inner membrane.
Conclusion: In a plant cell, both the nucleus and the chloroplasts are eukaryotic structures that require and possess their own individual surrounding membranes to maintain their internal environments.
