Question

What is the movement of cytoplasm within a cell called?

• A. Endocytosis
• B. Exocytosis
• C. Cytokinesis
• D. Cytoplasmic streaming

Hint:

Cytoplasmic streaming is crucial for the movement of materials within large cells and helps maintain cell functionality by facilitating even distribution of organelles and nutrients.

Answer 1

The Correct Option is D

Step 1: Understanding cytoplasmic streaming.

Cytoplasmic streaming, also known as cyclosis, is the directed movement of cytoplasm within a cell, crucial for the distribution of nutrients, organelles, and other cellular components. This movement is mediated by the cytoskeleton, specifically through the action of actin filaments and motor proteins like myosin.

Step 2: Explanation of alternative processes.

- (A) Endocytosis: The cellular uptake of substances via vesicle formation.

- (B) Exocytosis: The cellular expulsion of substances via vesicle fusion.

- (C) Cytokinesis: The physical separation of the cytoplasm during cell division.

Step 3: Conclusion.

Cytoplasmic streaming is vital for efficient intracellular transport, particularly in larger cells, such as those found in plants.
