state the difference between diffusion and osmosis
Answers
In diffusion the solute, I.e the substance that is dissolved, moves from area of its higher concentration to area of its lower concentration. It usually translates to movement is solute from an area if high osmolarity/osmolality(basically concentration) to the area of lower one.
In osmosis it's the movement of water from area of its higher concentration to area of water's lower concentration. What this actually means is that water moves from an area of low osmolarity/lality to the address of higher osmoles to equalise the concentrations. either the membrane/barrier is impermeable to solute, but allows water movement thus only osmosis occurs, or the membrane allows the movement of both the solute and water (solvent and this both osmosis and diffusion occur)
This is the basic difference between the two.
Others are like osmosis is always passive I.e never requires energy, while diffusion may be passive, facilitated(needing transport proteins but not energy) or active, being energy.
Hope it helps☺

Answer:
OSMOSIS
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
Examples of Osmosis:- It include red blood cells swelling up when exposed to freshwater and plant root hairs taking up water. To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane.
DIFFUSION
Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.
Examples of Diffusion:- Diffusion include the scent of perfume filling a whole room and the movement of small molecules across a cell membrane. One of the simplest demonstrations of diffusion is adding a drop of food coloring to water. Although other transport processes do occur, diffusion is the key player.
