Cell Size Variation and Examples — NEET Biology
📚 Practice ConceptCells differ greatly in size, shape and activities. For example, Mycoplasmas, the smallest cells, are only 0.3 μm in length while bacteria
Consider the following statements: 1. Ribosomes are present in both prokaryotic and eukaryotic cells, and are also found inside chloroplasts and mitochondria. 2. Mycoplasma are the smallest known cells, about 0.3 µm in size, and lack a cell wall. 3. Animal cells possess centrioles while most plant cells lack them. 4. In eukaryotes, the cytoplasm lacks membrane-bound organelles; only ribosomes are present. 5. Bacterial flagellum is structurally identical to eukaryotic flagellum, both showing the 9+2 arrangement of microtubules. Which of the above statements are correct?
