what is the meaning of prokaryotic and eukaryotic cell
Riya0303:
Both organisms are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane. The biggest difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus. They also have other membrane structures called organelles.

eg : Amoeba
eukaryotic cells are well defined cell and both multicellular and unicellular
eg : Human

Prokaryotic cell: They happen to be simpler and smaller. A prokaryotic cell doesn’t possess nucleus or other cell organelles. It is derived from a Greek word meaning before nuclei. They are reproduced through nuclear fission. It has a capsule which covers the outside of the wall, a cell wall which provides strength and rigidity, cytoplasm helping in cellular growth and a plasma membrane containing proteins, etc. The cytoplasm region contains ribosomes which are the smallest part and play a vital role in protein synthesis, mesosomes or the folding that help in cellular respirations, plasmids the small circle of DNA, pili, and flagella. Organisms belonging to the kingdom Monera possess prokaryotic cell.
Eukaryotic cell: They are complex and larger than the prokaryotic cells. It is also derived from a Greek word meaning good or true nuclei. They include all life kingdoms except monera. They consist of the cell wall which protects and supports the plasma membrane, the plasma membrane surrounds the cell and controls the entry and exit of certain substances, the nucleus containing DNA that stores all information, nuclear membrane surrounds the nucleus, nucleolus playing a vital role in protein synthesis, mitochondria are involved in performing their cellular functions, chloroplast being the subcellular sites of photosynthesis, endoplasmic reticulum helping in movement of materials, ribosome composed of proteins, Golgi bodies, lysosomes, vacuoles, cytoplasm, chromosomes, and centrosomes.
