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 else can I help you with?
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 a substance from an area of high concentration to an area of low concentration. Osmosis is the movement of water from an area of high concentration to an area of low concentration through a semi-permable membrance.
What is a special form of diffusion where water moves from an area of high water concentration to an area of low water concentration?
This is not special at all, it is what happens normally. You can also think of it as water moving down a solute gradient (from low solute concentration to high solute concentration, till the concentrations are the same. The name for this process is osmosis.
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 not called diffusion. Diffusion is the movement of substances from an area of higher concentration to an area of lower concentration. The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called filtration. Filtration is a passive process driven by the pressure difference across a membrane.
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.
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.
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.
What is the difference between the processes of osmosis and diffusion?
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Osmosis is the movement of water from an area of high concentration to an area of low concentration through a semi-permable membrance.
How is osmosis related diffusion?
Osmosis and diffusion are similar in that there is a net movement of molecules from a high concentration of those molecules to a lower concentration. Osmosis is a special type of diffusion that deals with the movement of water only. Osmosis also deals with a semipermeable membrane (like our cell membranes). Diffusion can occur anywhere such in a glass of water when you add sugar but it can occur around cells.
Whats the difference between osmosis and diffusion?
In diffusion, molecules travel from a higher concentration to a lower concentration. When you put a drop of ink in a glass of water, the spreading of the ink in the water is called diffusion. Similarly, if you spray an air freshener in one corner of a room, eventually people on the other side of the room will be able to smell it as well because the scent has diffused. In osmosis, molecules also travel from higher concentration to a lower concentration. However, osmosis specifically refers to the movement of WATER molecules. Both of these types of transport are examples of passive transport, which requires no energy.
What is the difference between diffusion or osmosis?
Diffusion is the process of air particles or molecules that moves from a point of higher concentration to point of lower concentration until the molecules are equally distributed among the particular area ,Osmosis is the process of water particles from a point of higher concentration to a point of lower concentration until the molecules are equally balance on each side of the membrane.
What is called when a molecule moves across a semipermable membrane into a region of a 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.
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! :)
