Which structures distinguish cells in multicellular plants and animals from those of unicellular organisms, and why are cells important for identifying organs and their functions?

Explanation:

All multicellular organisms are eukaryotes. Eukaryotes may also be single-celled. Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.

Outer skin cells form flattened stacks that protect the body from the environment. Muscle cells are slender fibers that bundle together for muscle contraction. The cells of multicellular organisms may also look different according to the organelles needed inside of the cell.
