Three ways that substances can move into and out of a cell?
One way is diffusion, another is osmosis and Active transport.
What substances conducts electricity in an aqueous solution?
Any substance that dissolves in water, increases the conductivity of water. The most effective substances are salts.
How does osmosis occour?
It occurs when the medium surrounding the cell has a higher water concentration than the cell, the cell will gain water. At the same time many important molecules, and particles for growth, also move from one cell to another.
What moves substances in and out of a cell?
Most molecules can move in and out of a cell, but different molecules have different methods of getting in- Small Non-Polar molecules can diffuse across the lipid bilayer Medium sized molecules of any kind require a specific protein channel HUGE MOLECULES require a process called endo and exocytosis
In osmosos how do molecules move?
Water molecules move with the help of membrane proteins called aquaporins, which regulate the movement of water in an out of the cell. Because of the dual nature of the membrane (hydrophobic and hydrophilic), water doesn't simply diffuse in an out, although a certain percentage can slip in between phospholipids.
Are many short hair-like structures on the surface of the cell that help move the cell or move substances past the cell?
cilia
What controls which substances can move in and out of cells?
Cell membrane controls which substances can move in and out of a cell. It is the dynamic boundary of cell
How do substances like co2 and move in and out of the cell?
By the process of diffusion and osmosis.
When substances move through a cell membrane by diffusion the cell uses a lot of energy to move those substances. Is this true or false?
a cell can only diffuse water, right? so it must be false cause that requires no energy
ARE many short hair like structures on the surface of a cell that help move the cell or move substances past the cell?
Both, there are two different hair like structures on cells.
What are 3 substances the can move in and out of the cell?
alcohol, water, oxygen and carbon dioxide can all dissolve through the lipids in the cell membrane.
What controls which substances can move in and out of a cell?
The cell membrane regulates the movement of substances in and out of the cell.How does it do this? The phospholipid bilayer is impermeable to most substances, allowing across only small, uncharged molecules such as those of oxygen, carbon dioxide, and water. The only way for other substances to cross the membrane is via transport proteins (channel and carrier proteins). These are selective, and therefore control what enters and what leaves the cell.
What is the name of the hair-like structures on a sponge cell that moves back and forth to help move water or nutrients or waste through the canal?
The hair like structures on sponge cells can be either cilia or flagella. These structures project from the surface of the cell and help to move substances.
Which type of molecule can move passively across the membrane?
Water can move passively through a membrane by moving through the pores of a cell. Other substances cannot move through a cell membrane.
What will happen when a plant is moved from a fresh water environment to a salt water environment?
Because substances move from areas of higher concentration to areas of lower concentration, the water would move either in or out of the cell. In the fresh water, there was a lower concentration inside the cell, so the water moved into the cell. In the salt water, there would be less water on the outside of the cell, so the water would move out of the cell.
What is a complex molecule that is embedded in the cell membrane that helpss move substances move into and out of a cell?
Transport protein
How would substances move in and out of a living cell?
by the chloroplast
