Which cell structures are seen in all cell types? check all that apply.

- dna

- cytoplasm

- nucleus

- ribosomes

- cell membrane

The cell structures seen in all cell types are DNA, Cytoplasm, Ribosomes, and Cell membrane.

DNA ( deoxyribonucleic acid) is the genetic material of all living organisms. It stores genetic information in the form of nucleotide sequences, which is passed from one generation to the next generation.

Cytoplasm is the fluid compartment of the cell, which is the site for all essential metabolic reactions of the cell like glycolysis.

Ribosomes are the specialized organelle, which act as the site for the synthesis of proteins in the cell.

Cell membrane is a protective and selectively permeable membrane around all living cells. It regulates the transport of substances in an out of the cell.
