Diffusion is crucial for flatworms as it facilitates the exchange of gases, nutrients, and waste products due to their lack of a circulatory system. Their flat, thin bodies provide a large surface area relative to their volume, allowing efficient diffusion to occur directly through their skin. Oxygen diffuses into their bodies from the surrounding water, while carbon dioxide and metabolic wastes diffuse out, supporting their basic physiological functions. This reliance on diffusion limits their size and habitat to moist environments where diffusion can occur effectively.
no answer.
it plays the cool side
well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration

hai :) it is in your book dont be lazyass.
its traditional

They act as barriers to the diffusion of certain substances.Read more: What_role_does_the_cellular_membrane_play_in_passive_transport
Proteins play a role in facilitated diffusion by acting as channels or carriers that help specific molecules pass through the cell membrane. These proteins facilitate the movement of molecules that are too large or polar to pass through the membrane on their own.
Before diffusion there is a higher concentration of oxygen molecules outside the cell than inside the cell. After diffusion the concentration of oxygen molecules is the same outside and inside the cell.
The plasma membrane of a cell plays a role in diffusion.
