Question

‘Cytoplasmic streaming’ is only unique to eukaryotic cells because of presence of

• A. Tubulin
• B. Actin and myosin
• C. Microfilaments
• D. Both a and c

Answer 1

The correct option is D Both a and c

Cytoplasmic streaming is the movement of cytoplasm within a living cell. Cytoplasmic streaming, also called cyclosis, transports nutrients, enzymes, and larger particles within cells, enhances the exchange of materials between organelles, as well as between cells. In some unicellular organisms, such as amoeba, it provides the mechanism for cell locomotion. It is thought that microfilaments provide the driving force for, and control the direction of, the streaming.
