1. passive or active transport (8 points)

☑️ pinocytosis a. passive
b. active
☑️ simple diffusion
☑️ facilitated diffusion
☑️ phagocytosis
☑️ exocytosis
☑️ sodium potassium pump
☑️ osmosis
☑️ endocytosis

Explanation:

• Pinocytosis: Active (needs energy to engulf fluid).
• Simple diffusion: Passive (no energy, high to low).
• Facilitated diffusion: Passive (no energy, uses channels).
• Phagocytosis: Active (energy to engulf particles).
• Exocytosis: Active (energy to release substances).
• Sodium - potassium pump: Active (uses ATP).
• Osmosis: Passive (water movement, no energy).
• Endocytosis: Active (energy to take in substances).

Answer:

• pinocytosis: b. active
• simple diffusion: a. passive
• facilitated diffusion: a. passive
• phagocytosis: b. active
• exocytosis: b. active
• sodium potassium pump: b. active
• osmosis: a. passive
• endocytosis: b. active
