Web21 mei 2024 · Only eukaryotes have membrane-bound organelles and a nucleus. Prokaryotes divide via using binary fission, while eukaryotic cells divide via mitosis. Eukaryotes reproduce sexually through meiosis, which allows for genetic variance. Prokaryotic cells reproduce asexually, copying themselves. Web21 aug. 2024 · Classification As organized in the Three Domain System, prokaryotes include archaeans and bacteria. Eukaryotes include animals, plants, fungi and protists (ex. algae ). Typically, eukaryotic cells are more complex and much larger than prokaryotic cells. On average, prokaryotic cells are about 10 times smaller in diameter than eukaryotic cells.

WebTherefore, prokaryotes are the earliest and most primitive form of life that evolved into complex eukaryotic cells approximately 1.8 billion years ago. They can be differentiated based on genetic materials enclosed by a nuclear envelope. Prokaryotes do not possess membrane-bound organelles, while eukaryotes do. Their four main structures are the plasma membrane, cytoplasm, ribosomes and genetic material (DNA and RNA). Cell Wall While some eukaryotic cells have cell walls , such as those in plants and fungi, almost all prokaryotic cells have them, and they are chemically distinct from those of eukaryotes.
