Eukaryotic Cell vs. Prokaryotic Cell
Eukaryotic cells do have a nucleus but Prokaryotic cells do not. Prokaryotic cells usually only have one chromosomes when Eukaryotic cell have more than one. Eukaryotic cells have mitochondria but Prokaryotic cells do not. Prokaryotic cells are usually unicellular and Eukaryotic cells are usually multicellular. Also Eukaryotic cells are larger than Prokaryotic cells. Both Eukaryotic and Prokaryotic cell have vacuoles. Both cells have vesicles as well. Prokaryotic Cell Eukaryotic Cell The division amongst prokaryotes and eukaryotes is considered to be the most significant difference among groups of organisms. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the arrangement of chromosomal DNA. Prokaryotes were the only form of life on Earth for millions of years until more complex eukaryotic cells came into being through the development of evolution.
Animal Cell vs. Plant Cell Both Plant and Animal cells have cytoplasm. Both Animal and Plant cells have nuclei, ribosomes, mitochondria, and Golgi apparatus. Flagella can also be found in both Plant and Animal cells. Some differences are that Animal cells don’t have a cell wall but Plant cells do and they are formed by cellulose. Animal cells have one or more small vacuoles whereas plant cells have one large central vacuole that can take up to 90% of cell volume. Plant cells have chloroplast for photosynthesis to create their own food whereas animal cells do not have chloroplasts. In plant cells, the function of vacuoles is to store water and maintain turgidity of the cell. Vacuoles in animal cells store water, ions and waste. Animal cells have an irregular shape where Plant cells have a fixed shape. Plant
