The image is a flowchart about transport across the cell membrane, and it asks you to match terms from a list at the bottom to their correct spots in the chart. Below is the solution with explanations for each term placement.
Key Concepts
1.
Passive Transport: Movement of substances from high concentration to low concentration (down the concentration gradient). No energy is required.
2.
Active Transport: Movement of substances from low concentration to high concentration (against the concentration gradient). Requires energy (ATP).
3.
Facilitated Diffusion: Passive transport that requires a protein channel or carrier but does not require energy.
4.
Osmosis: The diffusion of water across a semipermeable membrane.
5.
Endocytosis/Exocytosis: Bulk transport mechanisms involving the movement of large particles or molecules into or out of the cell.

Explanation of Each Term Placement
1.
Passive Transport: Substances move from high to low concentration without energy.
-
Osmosis: Water moves across a membrane.
-
Simple Diffusion: Movement of gases like CO₂ and O₂.
-
Facilitated Diffusion: Requires a protein channel but no energy.
2.
Active Transport: Substances move from low to high concentration, requiring energy (ATP).
-
Na⁺/K⁺ pump: Moves ions against their concentration gradient.
-
Endocytosis: Bulk transport into the cell (e.g., phagocytosis by an amoeba).
-
Exocytosis: Bulk transport out of the cell (e.g., secretion of hormones).

Final Answer
The completed flowchart matches the terms as follows:
-
Left Side: passive transport, osmosis, simple diffusion, facilitated diffusion, protein channel, equilibrium.
-
Right Side: active transport, ATP energy, Na⁺/K⁺ pump, endocytosis (example: amoeba eating), exocytosis (example: hormone export).
