4. The cell membrane below is divided into three sections to show three different types of transport that can occur across the membrane. For each type of transport: a. draw and label the type of molecule that would use that specific transport (water, glucose, oxygen, etc.) and b. draw an arrow to represent which direction the molecule would be moving across the cell. Diffusion Osmosis Active Transport

Question
**Cell Membrane Transport Mechanisms:** 4. The cell membrane below is divided into three sections to show three different types of transport that can occur across the membrane. For each type of transport: a. **Draw and label** the type of molecule that would use that specific transport (water, glucose, oxygen, etc.) b. **Draw an arrow** to represent which direction the molecule would be moving across the cell. --- ### Diagram Explanation: The diagram features a three-part illustration of a cell membrane showing different types of transport mechanisms - Diffusion, Osmosis, and Active Transport. #### **Diffusion:** - **Description:** Diffusion is the passive movement of molecules or particles from an area of higher concentration to an area of lower concentration. - **Molecules Involved:** Generally small, nonpolar molecules like oxygen or carbon dioxide. - **Direction:** This is generally from the outside (high concentration) towards the inside of the cell (low concentration). #### **Osmosis:** - **Description:** Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. - **Molecule Involved:** Water (H₂O) molecules. - **Direction:** From a region of lower solute concentration (hypotonic) to higher solute concentration (hypertonic) across the cell membrane. #### **Active Transport:** - **Description:** Active transport requires energy (ATP) to move molecules against a concentration gradient, from an area of lower concentration to an area of higher concentration. - **Molecules Involved:** Ions like Na⁺, K⁺, Cl⁻, or larger molecules like glucose. - **Direction:** From the inside of the cell (low concentration) to the outside (high concentration), or vice-versa, depending on the specific needs of the cell. **Note:** The diagram does not include arrows or labeled molecules; these should be added to show the direction and type of molecule for each process as described.
