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 movement of the cytoplasm within a cell to distribute nutrients, organelles, and other substances more effectively. This process is facilitated by the cytoskeleton, specifically actin filaments and motor proteins like myosin.

Step 2: Explanation of other options.

- (A) Endocytosis: This is the process by which cells engulf substances into vesicles.

- (B) Exocytosis: This is the process of expelling substances from the cell.

- (C) Cytokinesis: This refers to the division of the cytoplasm during cell division.

Step 3: Conclusion.

Cytoplasmic streaming is essential for intracellular transport and is especially prominent in large cells, such as plant cells.
