Question

What is the movement of cytoplasm within a cell called?

• A. Diffusion
• B. Osmosis
• C. Cytoplasmic streaming (Cyclosis)
• D. Active transport

Hint:

Cyclosis = Cytoplasmic streaming. It helps circulate nutrients, organelles, and metabolites inside large cells, especially plant cells.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks for the technical term used to describe the internal flow or movement of the fluid (cytoplasm) inside a living cell.
Step 2: Detailed Explanation:
Intracellular transport and the distribution of nutrients/organelles are often facilitated by the physical movement of the cytoplasm.
- Diffusion and Osmosis are passive transport mechanisms across membranes.
- Active transport is the movement of molecules against a gradient using ATP.
- Cyclosis, also known as cytoplasmic streaming, is the directed flow of the cytosol and organelles around the large fungal or plant cell vacuoles. This is driven by the cytoskeleton (actin filaments) and motor proteins (myosin).
Step 3: Final Answer:
The specific term for this internal fluid movement is Cytoplasmic streaming or Cyclosis.
