Diffusion in cells?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. In cells, diffusion plays a key role in transporting substances like oxygen, carbon dioxide, and nutrients across cell membranes. This process helps maintain cellular function by ensuring a balance of molecules inside and outside the cell.
Is water found in the cell membrane?
The same way that air influences the shape of a balloon. When the cell is in the proper environment water enters the cell and it is the proper shape. When the solute concentration outside the cell is too high the water leaves the cell and it shrivels.
What kind of environments causes water to enter or leave the cell?
Water Movement across a cell membrane is called Osmosis. And it is dependent on the concentration of ions on each side of the cell membrane. If the concentration is higher on the inside of the cell water rushes in to dilute the ion concentration and get it to equal the outside concentration of ions and this is called hypotonic. If the concentration is higher outside the cell water will rush out of the cell to help dilute the concentration outside the cell and get the two concentrations to become equal and is called hypertonic. If the concentration is equal in both outside and inside the cell there will be no water movement and is called isotonic. Osmosis
What is a passive method by which glucose molecules enter cells?
Passive diffusion is a method by which glucose molecules enter cells. Glucose can diffuse through the cell membrane down its concentration gradient without the need for energy input from the cell.
Does oxygen enter a cell by diffusion or osmosis?
Oxygen enters a cell by diffusion, which is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis, on the other hand, is the movement of water molecules across a selectively permeable membrane.
What if a cell has a lower concentration outside the cell?
There are two basic ways that individual molecules can enter (or leave) a cell.1. Diffusion. This is the movement of particles from a region of high concentration to a region of low concentration. So if the concentration of the molecule is higher outside the cell it can enter by diffusion. However diffusion can only take place down a concentration gradient ie from a high to a low concentration.2. Active transport. This is the movement of particles against their concentration gradient (ie from a low to a high concentration), using energy provided by the cell (ie ATP produced by respiration). So if a molecule is at a higher concentration inside the cell it can only be absorbed by active transport.
Describe the conditions needed for molecules to enter a cell passively?
Molecules can enter a cell passively through processes like simple diffusion or facilitated diffusion. For this to occur, the molecule must be small, nonpolar, and/or able to pass through ion channels or carrier proteins. Additionally, there must be a concentration gradient across the cell membrane to drive the movement of molecules into the cell.
How does most water soluble materials get into a cell process by which molecules tend to move from an area of higher concentration to an area of lower concentration?
Most water-soluble materials enter a cell through the process of passive diffusion, where molecules move across the cell membrane from an area of high concentration to an area of low concentration. This movement occurs without the cell expending energy and helps maintain the balance of molecules inside and outside the cell.
What effect does isotonic solution have on an egg?
Considering osmosis- If a hypertonic solution causes water molecules to leave an egg, and a hypotonic solution causes water molecules to enter a egg, an isotonic solution (where inside the egg and outside the egg the solute concentration is equal) water molecules would neither enter, nor leave a cell. I hope this helped :)

Oxygen molecules enter a cell by diffusion which is?
Diffusion is the movement of molecules or ions from high concentrated medium to low concentrated medium due to the continuous free movement of molecules, simply it's like spraying some perfume , air diffusion makes perfume molecules to move so that you can smell it every where in the room..

How does osmosis work in the process of cellular transport?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. In cellular transport, osmosis helps maintain the balance of water inside and outside the cell, allowing nutrients to enter and waste products to exit.
What is cell diffusion?
One way that substances enter a cell is through diffusion. Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration. When the molecules are even throughout a space it is called equilibrium.
