Question

why plasma membrane is called selectively permeable membrane how do substances like carbon dioxide water move in and out of the cell​

Answer 1

Answer:

Since it allows only selected material to pass through it that is why it's called selectively permeable membrane. Substance like water move in and out through by the process of osmosis while gases like CO2 moves in MD outby process called Diffusion.

Answer 2

The plasma layer is called a specifically permeable membrane since it controls the movement of substances all through the cells.

Why is it so?

• Only selective particles like water and vaporous atoms can go through the phone layer straightforwardly.
• It stops the progression of different particles towards the different sides.

Movement of $CO_{2}$:

• $CO_{2}$ is a vaporous atom and consequently, it moves all through the cell unreservedly by simple diffusion.
• Diffusion is a cycle where the particles cooperate and move from a locale of higher concentration to lower concentration.

Movement of $H_{2} O$:

• $H_{2} O$ moves all through the cell as a natural by osmosis which is a type of diffusion.
• In osmosis, the water atoms move from lower solute fixation to higher solute concentration through the cell layer.
