Question

correctly match the term and definition: the fusion of a vesicle with the plasma membrane to move substances out of the cell. options: exocytosis, endocytosis, primary active transport, diffusion, osmosis, i dont know yet

Explanation:

To solve this, we analyze each option:

• Exocytosis: Defined as the fusion of a vesicle with the plasma membrane to secrete (move out) substances from the cell.
• Endocytosis: Involves bringing substances into the cell (opposite of the definition).
• Primary active transport: Uses energy (e.g., ATP) to move ions against a gradient, not via vesicle - plasma membrane fusion.
• Diffusion: Passive movement of substances down a concentration gradient, no vesicle involved.
• Osmosis: Diffusion of water across a semi - permeable membrane, no vesicle involved.

So the term that matches the definition is Exocytosis.

Answer:

The correct option is the one with "Exocytosis" (the first option in the answer choices list, with the label "I AM UNSURE" above it but the correct term is Exocytosis). In the format of the options: The option corresponding to Exocytosis (the circular radio button next to "Exocytosis" in the answer list). If we consider the options as presented: The correct option is the one where the text is "Exocytosis" (the first selectable option after "I AM UNSURE" in the answer panel).
