Comparative Cell Structure Prokaryotic Vs Eukaryotic
Comparative Cell Structure Prokaryotic Vs Eukaryotic — a labelled NEET Biology diagram with a definitions lexicon.
Comparative Cell Structure (Prokaryotic vs Eukaryotic) Labelled parts: Prokaryotic cell (E. coli), Cell wall, Cell membrane, Cytoplasm, Nucleoid, Circular DNA, Plasmid DNA, 70S ribosomes, Flagellum, Eukaryotic animal cell, Nucleus, Nuclear envelope, Rough endoplasmic reticulum, Smooth endoplasmic reticulum, Golgi apparatus, Lysosomes, Centrioles, 80S ribosomes, Eukaryotic plant cell, Large central vacuole, Chloroplasts, Mitochondria. These are small, circular, extrachromosomal pieces of DNA found in bacteria. They replicate independently of the main bacterial chromosome. FYI: Plasmids often carry genes conferring antibiotic resistance, making them crucial tools in genetic engineering and bacterial pathogenesis. This organelle is involved in lipid synthesis, detoxification of drugs and poisons, and the storage of calcium ions (especially in muscle cells). It lacks ribosomes. FYI: In muscle cells, the SER is specialized and is called the sarcoplasmic reticulum (SR), where it stores high concentrations of Ca 2+ ions. This large, membrane-bound organelle is characteristic of mature plant cells. It maintains turgor pressure, stores water, nutrients, and waste products. FYI: The vacuole is enclosed by a membrane called the tonoplast, which regulates the movement of substances into and out of the vacuole.
