Which of the following organelles are enclosed by a double membrane?
A
Chloroplasts
B
Mitochondria
C
Golgi apparatus
D
Ribosomes
Verified step by step guidance1
Understand that organelles with a double membrane have two lipid bilayers surrounding them, which is a key feature for certain organelles involved in energy conversion and synthesis.
Recall that chloroplasts are organelles found in plant cells and some protists, responsible for photosynthesis. They have a double membrane, with an inner and outer membrane, and contain their own DNA.
Remember that mitochondria are known as the powerhouses of the cell, found in most eukaryotic cells. They are involved in energy production through cellular respiration and also have a double membrane structure, with an inner and outer membrane, and contain their own DNA.
Consider the Golgi apparatus, which is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell. It is not enclosed by a double membrane; instead, it consists of a series of flattened membrane-bound sacs.
Recognize that ribosomes are the sites of protein synthesis in the cell. They are not membrane-bound organelles and thus do not have a double membrane. They can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
