Level 1
Process that moves any material from high concentration to low concentration
What is Endocytosis?
Cell process that moves substances against a concentration barrier
What is ACTIVE transport?
A barrier that chooses what can go through
What is selectively permeable?
Water moving into the root cells of a plant
What is Osmosis?
Transport when fluid/solids are taken into the cell by making a small vesicle
What is endocytosis?
true or false?
The cell membrane is an impenetrable barrier
What is FALSE?
True or False?
Glucose is the energy required for active transport
What is FALSE?
Type of membrane proteins that have a straight path for particles to travel in and out of the cell
What is a channel protein?
Two solutions that have the same solute concentration
What is Isotonic?
Type of transport that occurs when a large cell consumes a smaller cell.
What is phagocytosis?
The movement of water through a semipermeable membrane is called __________________.
What is Osmosis?
Type of cell transport used to push particles out of the cell.
What is exocytosis?
Type of diffusion that requires carrier proteins or channel proteins to move substances in and out of a cell
What is Facilitated diffusion?
Sodium Potassium pump is this type of transport
What is active transport?
What happens to a cell placed in a hypotonic solution?
What is water moving in to a cell causing it to swell?
The movement of substances across a cell membrane without the need of energy.
What is passive transport?
Part of a plant cell that does NOT change during cell transport
The cell wall
Active transport requires the use of what energy storing molecule when moving particles in and out of a cell
What is ATP?
A solution with a higher concentration of solutes is called _________________.
What is Hypertonic?
How does particle size affect a molecule's ability to move a cross a cell membrane?
It easier for small molecules to diffuse across the cell membrane
Direction passive transport moves
What is WITH the concentration barrier?
Raisins soaked in water are in which type of solution?
What is Hypotonic solution?
Type of transport that goes WITH the concentration gradient
What is passive transport?
Type of protein used to carry ions across a cell membrane
What is a carrier protein?
Explain how the surface area of a cell increases and decreases
Endocytosis decreases the cell membrane and exocytosis increases the cell membrane by adding back to the membrane.
