Concentration. It will generally flow from an area of high concentration to an area of low concentration.
Diffusion is the main method by wich small molecules move across the cell membrane. while many cellular processes depend on osmosis because cells cannot function properly without adequate water. Facilitated diffusion works through channels and Osmosis only works with water.
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.
No, the rates of absorption and diffusion are not constant for all molecules. They depend on factors like molecular size, charge, solubility, and membrane permeability. Larger molecules, charged molecules, and less lipid-soluble molecules typically have slower rates of absorption and diffusion compared to smaller, uncharged, and lipid-soluble molecules.
Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.Explanation:Diffusion is a passive process. It is like when you open a bottle of perfume, soon the whole room will be covered with its smell. From region where the concentration is high, the molecules move to the regions where the concentration is low down the concentration gradient unless equilibrium is reached. Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.
Yes, living organisms that depend on diffusion for processes like respiration or nutrient exchange include single-celled organisms like protozoa, small invertebrates like flatworms and roundworms, aquatic organisms like sponges, and even some small insects. Diffusion allows them to exchange gases, nutrients, and waste products with their environment, essential for their survival.
Facilitated diffusion depends on specific carrier proteins located in the cell membrane that help transport molecules across the membrane. These carrier proteins are selective and facilitate the movement of specific molecules based on their size, shape, and charge. Additionally, facilitated diffusion relies on the concentration gradient of the molecules to drive their movement across the membrane.
Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. The direction of osmosis depends on the relative solute concentrations on either side of the membrane.
All forms of passive transport depend on the movement of molecules or ions across a cell membrane without the use of cellular energy (ATP). This includes processes such as diffusion, osmosis, and facilitated diffusion.

The average diffusion rate of urea through a 200 MWCO (Molecular Weight Cut-Off) membrane would depend on various factors such as concentration gradient, temperature, and membrane properties. Typically, higher MWCO membranes allow for faster diffusion rates of smaller molecules like urea due to their larger pore sizes. Specific experimental data would be needed to calculate the exact diffusion rate in this scenario.
Facilitated diffusion is the passive transport of molecules across a membrane with the help of transport proteins. This process occurs down the concentration gradient and does not require energy. In contrast, active transport requires energy to move molecules against their concentration gradient through specific transport proteins.
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.

Larger molecules, charged molecules, and less lipid-soluble molecules typically have slower rates of absorption and diffusion compared to smaller, uncharged, and lipid-soluble molecules.
Cells depend on diffusion to allow the movement of molecules like oxygen, nutrients, and waste products across their membranes. Osmosis is a type of diffusion specific to water molecules, where water moves from areas of lower solute concentration to areas of higher solute concentration to maintain balance inside and outside the cell. Both processes are crucial for maintaining the proper internal environment of the cell and ensuring its survival.
Avascular tissues receive nutrients through diffusion from neighboring blood vessels or surrounding tissues. These tissues depend on a close proximity to a blood supply to maintain their metabolic functions.
