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.
