Difference between prokaryotic and eukaryotic cell for class 9

Eukaryotes and prokaryotes Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi. • Cells of bacteria are called prokaryotic cells . • Cells of animals, plants and fungi are called eukaryotic cells . Comparing cell types Eukaryotic cell Prokaryotic cell Size Most are 5 μm – 100 μm Most are 0.2 μm – 2.0 μm Outer layers of cell Cell membrane - surrounded by cell wall in plants and fungi Cell membrane - surrounded by cell wall Cell contents Cytoplasm, cell organelles include mitochondria, chloroplasts in plants and ribosomes Cytoplasm, ribosomes, no mitochondria or chloroplasts Genetic material DNA in a nucleus - plasmids are found in a few simple eukaryotic organisms DNA is a single molecule, found free in the cytoplasm - additional DNA is found on one or more rings called plasmids Type of cell division Mitosis Binary fission A group of organisms called Archaea are also prokaryotic.

Cells are any life's primary unit. Thus it's important to learn and differentiate between the two major cell types- prokaryotic and eukaryotic cells. But, knowing them isn't enough. Do you have concepts strong enough to tell the difference between prokaryotic and eukaryotic cell? You don't? Then by the end of this article, you'll have a good understanding of both- their similarities and differences! What is Prokaryotic and Eukaryotic Cell? Before getting excited about- the difference between prokaryotic and eukaryotic cell, it's important to understand them. Not together but individually. The forthcoming section does that for you. So keep reading and learn about prokaryotic and eukaryotic cells. Prokaryotic Cell The simplest types of cells are- prokaryotic cells. They are found in organisms like archaebacteria and bacteria. A characteristic that makes them stand out is- the lack of membrane-bound organelles and nuclei. Also if they have a genetic material that’s circular and different from DNA. Organisms that come under prokaryotes are crucial for completing processes like- decomposition and nutrient cycling. Eukaryotic Cell In comparison to prokaryotic cells, eukaryotic cells are much more complex. The eukaryotic cells are found in a range of organisms like- plants, animals, fungi, and protists. They differ from prokaryotes by having membrane-bound organelles like- the Golgi apparatus, mitochondria, etc. Eukaryotes exhibit cellular specialisation that’s greater than proka...

Prokaryotic cells: Prokaryotic cells are cells that do not have a true nucleus and membrane-bound organelles. Eukaryotic cells: Eukaryotes are cells that contain a membrane-bound nucleus and membrane-bound organelles. S.no Prokaryotic cell Eukaryotic cell 1 Prokaryotic cells are always unicellular. Eukaryotic Cells are unicellular and multicellular. 2 The nucleus is absent. Instead, they have a nucleoid region in the cell. The nucleus is present. The nuclear membrane encloses the nucleus. 3 Only a single chromosome is present. More than one chromosomes are present. 4. They lack membrane-bound organelles. Membrane-bound organelles are present. 5. They have only 70S ribosomes. Both 70S and 80S ribosomes are present in eukaryotes. 6. Cell division occurs by binary fission or budding. Cell division occurs by meiosis and mitosis. 7. The cell wall is made up of peptidoglycan. The cell wall is made up of cellulose in plants and chitin in fungi. 8. Asexual reproduction occurs in prokaryotes. Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. 9. The flagella are smaller and simple in structure. The flagella are larger and more complex in structure . 10. Examples- Bacteria and Archaea Examples - Plant and animal cells.
