The cell membrane, specifically the phospholipid bilayer, is responsible for facilitating diffusion, osmosis, and active transport of molecules in and out of the cell. Various proteins, such as ion channels and pumps, play a role in active transport processes by assisting in the movement of specific molecules against their concentration gradients.

What isit called when a molecule moves across a semipermeable membrane into a region of higher concentration?
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.
What is the difference between the processes of osmosis and diffusion?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while osmosis specifically refers to the movement of water molecules across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis involves the movement of only water molecules, whereas diffusion can involve any type of particle.
What is a special form of diffusion where water moves from an area of high water concentration to an area of low water concentration?
Osmosis is the special form of diffusion where water moves passively across a semi-permeable membrane from an area of high water concentration to an area of low water concentration to equalize the concentration on both sides.
IS The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called diffusion?
No, the movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called filtration, not diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
What branch of science deals with plants?
Botany is the branch of science that deals with the study of plants, including their structure, growth, reproduction, metabolism, and classification.

Is osmosis a passive or active transport and how?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.

Osmosis involves the movement of only water molecules, whereas diffusion can involve any type of particle.
How is osmosis related diffusion?
Osmosis is a specific type of diffusion that involves the movement of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. Diffusion, on the other hand, is the general process by which molecules move from an area of higher concentration to an area of lower concentration. Both processes involve the movement of particles to create a more balanced distribution.
Whats the difference between osmosis and diffusion?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration. In osmosis, water moves to equalize the concentration of solutes on both sides of the membrane.
What is the difference between diffusion or osmosis?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while osmosis specifically refers to the movement of water molecules across a selectively permeable membrane. Diffusion can involve any type of particle, while osmosis specifically deals with water molecules.

When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.
One form of passive transport that takes place across a membrane that lets water pass but keeps out many things that are dissolved in the water is called?
This is called osmosis since it deals with the passive movement of water.
What is the ability of the gas to completely spread out and mix with other substance?
This is entropy, the tendency for an ordered system to move to a state of lower energy (every thing evenly spread out). Brownian motion (haphazard random motion of molecules) accounts for the motion.

What does the minister of transport do?
A minister of transport literally deals with anything and everything dealing with transportation. Bus routes, cars, school buses you name it! :)
What is a special form of diffusion where water moves from an area of high water concentration to an area of low water concentration?
Osmosis is the special form of diffusion where water moves passively across a semi-permeable membrane from an area of high water concentration to an area of low water concentration to equalize the concentration on both sides.
