Question

An animal cell, a plant cell and a bacterium share the following structural features.

• A. Cell membrane, endoplasmic reticulum, vacuoles
• B. Cell wall, plasma membrane, mitochondria
• C. Cell wall, nucleus, cytoplasm
• D. Plasma membrane, cytoplasm, ribosomes

Answer 1

Answer: (D)

Plasma membrane, cytoplasm, ribosomes

The cell membrane (also known as the plasma membrane) is a biological membrane that separates the interior of all cells from the outside environment. Bacteria and plants also have the cell membrane. Cytoplasm is the jelly like material that makes up much of a cell inside the cell membrane, and, in eukaryotic cells, surrounds the nucleus. The organelles of eukaryotic cells, such as mitochondria, the endoplasmic reticulum and (in green plants) chloroplasts, are contained in the cytoplasm. All animals and plants are made of cells. Animal and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells also have a cell wall and often have chloroplasts and a permanent vacuole.
