Explanation:

Q1

To determine the type of transport for CO₂ movement from the atmosphere (high concentration) to plant cells (low concentration), we recall: Passive transport is the movement of substances from high to low concentration without energy, while active transport requires energy and moves against the gradient. CO₂ moves down its concentration gradient (high to low) and does not need energy. So it's passive transport.

• Transport Protein Requirement: Simple diffusion occurs directly through the lipid bilayer for small, non - polar molecules (like CO₂, which is non - polar and small). Facilitated diffusion needs transport proteins. Since CO₂ can pass through the lipid bilayer on its own, it does not require a transport protein.
• Diffusion Type: Simple diffusion is the movement of molecules through the membrane without the help of transport proteins, down the concentration gradient. As CO₂ moves down its concentration gradient without a transport protein, it is simple diffusion.

Answer:

Passive transport
