Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
No matter what, all cells have which organelles in common?
A
Cell Membrane
B
Cytoplasm
C
DNA
D
Ribosomes
E
Mitochondria
Explanation: 

Detailed explanation-1: -All living cells contain ribosomes, whether they are prokaryotic or eukaryotic cells. However, only eukaryotic cells also contain a nucleus and several other types of organelles. An organelle is a structure within the cytoplasm of a eukaryotic cell that is enclosed within a membrane and performs a specific job.

Detailed explanation-2: -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-3: -The nucleolus, an organelle is associated with Ribosome function.

Detailed explanation-4: -Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria. However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.
