A	nucleus
B	cell membrane
C	rough endoplasmic reticulum
D	vacuole

Explanation:

Detailed explanation-1: -Nucleus. The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle, which functions as the control centre of the cellular activities and is the storehouse of the cell’s DNA.

Detailed explanation-2: -Final answer: Organelles that are surrounded by two membranes are Nucleus and mitochondria.

Detailed explanation-3: -The double membrane-bound organelles are mitochondria, chloroplasts and the nucleus.

Detailed explanation-4: -Nucleus-which contains DNA and controls the synthesis of proteins. The nucleus contains a nucleolus, which is a dense body where ribosomes are made. The nucleus is surrounded by a double membrane, known as the nuclear envelope, with nuclear pores.

Detailed explanation-5: -Characteristics of the mitochondria. Characteristics of chloroplasts. Functions of the mitochondria: Functions of chloroplasts:
