biology movements of substance in and out of cells,diffusion and osmosis

What is the process by which substances produced by the cell pass out of the cell?

The process by which substances produced by the cell pass out of the cell is called secretion.

Explain why the process of secretion is important for the body

Secretion is important because it allows the body to remove harmful waste (e.g., carbon dioxide, which can be toxic) and release useful substances (e.g., enzymes for digestion or hormones for body regulation).

Give one example of a waste product and one example of a useful substance that a cell may release.

Waste product: Carbon dioxide or urea

Useful substance: Enzyme (e.g., amylase) this is an enzyme that breaks down starach into sugar or hormone (e.g., insulin) this is a hormone that controls blood sugur levels

How does the permeability of the cell membrane differ from that of the cell wall?

The cell membrane is differentially permeable, meaning it controls what enters and leaves the cell by allowing only certain substances to pass through.

In contrast, the cell wall is freely permeable, allowing most substances to pass through without restriction.

Give the definition of the following term osmosis ?

osmosis is the movement of water molecules through diffrentially permeable membrane from a place of high concentration to a place of low Consentration

Give the definition of the following Term diffusion and give examples

Diffusion is the movement of particles from an place of high consentration to and area of lower concentration and example is
