Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following do all cells have?
A
cytoplasm, plasma membrane, ribosome
B
cytoplasm, chloroplast, plasma membrane
C
ribosomes, cytoplasm, mitochondria
D
mitochondria, cytoplasm, nucleus
Explanation: 

Detailed explanation-1: -All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis.

Detailed explanation-2: -The interior of all cells consists of cytoplasm filled with a jelly-like substance called cytosol. Structures inside the cell are suspended in the cytosol. All living organisms have cells that contain genetic material (DNA).

Detailed explanation-3: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment.

Detailed explanation-4: -All living cells contain ribosomes, tiny organelles composed of approximately 60 percent ribosomal RNA (rRNA) and 40 percent protein. However, though they are generally described as organelles, it is important to note that ribosomes are not bound by a membrane and are much smaller than other organelles.
