Centrosome and Cell Division — NEET Biology
📚 Practice ConceptAnimal cells contain another non-membrane bound organelle called centrosome which helps in cell division.
Which of the following statements concerning eukaryotic cell organelles are correct? S1: Ribosomes are non-membrane bound organelles found in the cytoplasm, as well as within chloroplasts (in plants) and mitochondria. S2: Centrosomes are non-membrane bound organelles present in plant cells, helping in cell division. S3: The endomembrane system includes endoplasmic reticulum, golgi complex, lysosomes, vacuoles, and mitochondria due to their coordinated functions. S4: Plant cells possess cell walls, plastids, and a large central vacuole, which are generally absent in animal cells. S5: Eukaryotic ribosomes are 80S, composed of 60S and 40S subunits, while prokaryotic ribosomes are 70S, with 50S and 30S subunits.
