What is Phagocytes?
When the concentration outside the cell is lower and water moves into the cytosol
What is hypotonic?
Osmosis moves this way in concentrations.
What is high to low concentration?
Diffusion moves this way in concentration.
What is high concentration to low concentration
This supplies the energy for active transport.
What is ATP?
These pinch off when the cell membrane encloses around molecules.
What is vesicles?
transport of solutes or fluids
What is Pinocytosis?
concentration is equal in and out of the cell
What is isotonic?
Diffusion across membranes is also know as
What is simple diffusion?
Sodium-Potassium pumps are found in these cells.
What is animal cells?
Pressure of water molecules on the cell wall of plant cells
What is turgor pressure?
When the concentration is higher outside of the cell and water moves out of the cytosol
What is hypertonic?
This is when turgor pressure is loss and the reason plants wilt.
What is plasmolysis?
When the amount of molecules on both sides becomes equal
What is equilibrium?
Process by which a substance is released from the cell through a vesicle, moving inside to outside
What is exocytosis?
specific proteins used to assist movement of molecules
What are carrier proteins?
Movement of large particles or whole cells
What is phagocytosis?
Organisms that live in hypertonic solutions use these organelles to remove water
What are contractile vacuoles?
Membrane proteins that transport ions such as salt and chloride
What are ion channels?
In active transport, how do substances move? Think about the concentration.
What is low to high concentration?
the difference in concentration of molecules across a distance
What is the concentration gradient?
This process is used by unicellular organisms when feeding
What is phagocytosis?
When water moves across the cell membrane
What is osmosis?
What is stretch of the cell membrane, electrical signals, and chemicals?
Process by which cells ingest external fluid, macromolecules, and large particles (other cells), moving outside to inside
What is Endocytosis?
