9 Define the item i- a) semipermeable membrane osmoisis.
Answers
Answer:
definition:Cell membranes are semipermeable, which means molecules can move through them. This is pretty important for cells to survive. Osmosis is where solvent molecules (usually water) move from one side of a cell membrane to the other. This happens because the concentration of a solute is higher on one side.
Explanation:
Semipermeable Membrane Definition. A semipermeable membrane is a layer that only certain molecules can pass through. ... Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass.
Osmosis is the movement of water through a semi-permeable membrane from a region of high concentration to a region of low concentration, tending to equalise the concentrations of the water. Osmosis is passive transport, meaning it does not require energy to be applied

Answer:
osmosis is defined as the movement of water molecules from the lower region to the higher region.
the cell wall is said to be freely permeable as it allows all the substance to pass through it the cell membrane is semipermeable
