Question

make sure the \animal cell\ tab at the top is selected. click \sample\ to view the animal cell under magnification. what are organelles? tiny units that work together to perform a single function tiny units that make up all animals structures that contain cells that keep the animal alive structures that perform different functions to keep the cell alive

Explanation:

To determine the correct description of organelles, we recall that organelles are specialized structures within a cell that perform specific functions to maintain the cell's life. Let's analyze each option:

• "tiny units that work together to perform a single function": This describes a tissue or a group with a single function, not organelles (which have diverse functions in a cell).
• "tiny units that make up all animals": This refers to cells (the basic unit of animals), not organelles (which are inside cells).
• "structures that contain cells that keep the animal alive": Organelles are inside cells, not containing cells.
• "structures that perform different functions to keep the cell alive": This matches the definition of organelles (specialized structures in cells with distinct functions for cell survival).

Answer:

The fourth option (from the left): "structures that perform different functions to keep the cell alive"
