which of the following organelles are enclosed by a double membrane?
Answer: The organelles enclosed by a double membrane in eukaryotic cells are:
-
Nucleus: The nucleus, which contains the cell’s genetic material (DNA), is surrounded by a double membrane called the nuclear envelope. This double membrane includes the inner and outer nuclear membranes.
-
Mitochondria: Mitochondria are often referred to as the “powerhouses” of the cell because they generate energy through cellular respiration. They are also enclosed by a double membrane, consisting of an outer mitochondrial membrane and an inner mitochondrial membrane.
-
Chloroplasts (in plant cells): Chloroplasts are organelles involved in photosynthesis, and they are found in plant cells. They are also enclosed by a double membrane, consisting of an outer chloroplast membrane and an inner chloroplast membrane.
These double membranes serve various functions, including compartmentalization and control of the exchange of molecules between the organelle’s interior and the surrounding cytoplasm.
