Chapter 3.4 QUESTION SCIENCE
What is osmosis?
Osmosis is Diffusion of water through a selectively permeable membrane.
How is osmosis related to diffusion?
Osmosis is related to diffusion because osmosis is the diffusion of water molecules through selectively permeable.
what is osmosis?
Osmosis is the diffusion of water molecules through the selectively permeable membrane.
What is passive transport?
Requires NO energy, Movement of molecules from high to low concentration, Moves with the concentration gradient
What causes Diffusion?
Since molecules are always moving the molecules collide with each other and then eover time the molecules will start to spread out and eventually they will be spread out.
Diffusion of oxygen?
The diffusion of oxygen beigins when their is a higher concentration of oxygen of molecules diffuse from the area of higher concentration.
A selectively permeable membrane separates solutions A and B. The concentration of water molecules in solution B is higher than that in solution A. Describe how water molecules move.
Water Molecules move threw the cell and then enters into a any organelle,
Describe how water molecules move through a cell membrane during osmosis.
Water molecules move through a cell membrane during osmosis when diffusion of water through selectively permeable membrane process happens into a cell.
Explain why transport proteins require energy to function in active transport?
transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.
There are 2 types of active transport?
Transport of proteins, and transport by englufing
By what process do small molecules move into cells?
Diffusion.
What are transport proteins?
Transporting proteins from one area to another.
What are the effects of Osmosis?
A osmosis cell will turn a donut shape with out the hole if keep oxygen and water balances inside it. On B the cell is deprived from water so it stores water until it runs out. The high water concentration there is to much water trying to get in the cell but the cell only lets in a little bit of the water and oxygen.
How is active transport different from passive transport?
Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. Passive transport requires no energy.
Why are cells small?
Cells are small because if the cells were big they would over size a part of are body to much.
What is osmosis?
Diffusion of water through a selectively permeable membrane
How do you transport proteins?
Explains The active transport of proteins. Transport engulfing explains the engulf of material to transport it.
what is a active transport?
Is the movement of materials through a cell membrane using cell membrane using cellular energy.
What is Diffusion?
Is the process by which a characterictic spreads
Use diffusion to explain what happens when you drop a sugar cube into a mug of hot tea
When you drop a sugar cube in a mug of hot tea it diffusion process happens and it disappears into tiny molecules of sugar
Active and passive transport how do they differ?
passive transport explains transport of dissolved materials through a cell membrane without energy. Active transport Explains transport of dissolved materials through a cell membrane WITH energy.
What is a select permeable?
some substances can pass through the membrane while others cannot
