Verified step by step guidance

Understand the concept of diffusion: Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. It occurs naturally and does not require energy input.

Identify the type of transport: Passive transport is a type of transport that does not require energy. It relies on the concentration gradient to move substances across cell membranes.

Relate diffusion to passive transport: Since diffusion involves the movement of oxygen gas from a higher concentration outside the cell to a lower concentration inside the cell without energy input, it is classified as passive transport.

Consider the options given: Active transport requires energy to move substances against their concentration gradient, which is not the case here. Therefore, active transport is not applicable.

Conclude the correct answer: Based on the explanation, the correct type of transport for oxygen gas diffusing into cells during respiration is passive transport.
