The compound that allows materials to move through cell membranes by osmosis is?
The compound that allows materials to move through cell membranes by osmosis is water. Water moves freely through cell membranes to maintain osmotic balance within the cell.
Where does the materials needed by cells come from?
Cells get the materials they need from the environment around them. Nutrients are obtained from food and water intake, oxygen is obtained through breathing, and other necessary molecules are absorbed through cell membranes. The cell then uses these materials to carry out various functions and processes to sustain life.
What materials are permeable to some ofthe substances but impermeable to the others?
Semi-permeable membranes are materials that allow certain substances to pass through while blocking others based on their size and charge. Examples include cell membranes in living organisms and dialysis membranes used in medical treatments. These membranes play a crucial role in biological processes and separations in various industries.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
What processes does not involve the uptake of materials into the cellinvolve the uptake of materials into the cell?
Processes that do not involve the uptake of materials into the cell include cell communication, gene regulation, and cell division. Processes that involve the uptake of materials into the cell include endocytosis, active transport, and pinocytosis.

The movement of water and dissolved materials through cell membranes?
osmosis

What do most of the food and waste materials that move into and out of a cell pass through?
They pass through the cell walls and or membranes depending on wether or not its a plant or animal cell. Animal cells have only membranes. Plant cells have both.

3 ways materials enter and leave cell?
Materials can enter a cell through processes like diffusion, facilitated diffusion, and active transport. These substances can leave a cell through processes such as diffusion, osmosis, and exocytosis.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.

What are like fences that allow materials to enter and leave a cell?
cell membranes
How multicellular organisms exchange materials?
Multicellular organisms exchange materials through mechanisms such as diffusion, active transport, and bulk flow. These processes occur through specialized structures like cell membranes, blood vessels, and respiratory or digestive systems, enabling the transport of gases, nutrients, and wastes throughout the organism's body.
What would happen to a cell if materials could not move across the cell membranes?
it will died
