Nucleus does not need a membrane but chloroplasts are surrounded by their own membrane.
Nucleus and chloroplasts are surrounded separately by their own membrane.
Nucleus is surrounded by membrane but chloroplasts do not need membrane.

Plant cells, like most eukaryotic cells, contain various membrane-bound organelles. The question asks about the membranes surrounding the nucleus and chloroplasts.
– The nucleus in plant cells is a prominent organelle enclosed by a double membrane known as the nuclear envelope.
– Chloroplasts, the sites of photosynthesis in plant cells, are also enclosed by a double membrane.
Therefore, both the nucleus and chloroplasts are surrounded separately by their own membranes.
Other double-membraned organelles in eukaryotic cells include mitochondria. Single-membraned organelles include the endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles. Ribosomes are not membrane-bound organelles.
