Unit 4: Cell Transport
There is a greater concentration of solute molecules OUTSIDE the cell than inside.
There is a LOWER concentration of solute molecules OUTSIDE the cell than inside.
There is the SAME concentration of solute molecules outside the cell as inside.
The pressure inside a plant cell caused by water pushing against the cell wall.
The SWELLING and BURSTING of animal cells when water enters. This happens when an animal cell is placed in a hypotonic solution.
Placing plant cells in a HYPOTONIC solution will causes the osmotic pressure to ______________.
The SHRINKING of plant cells when water leaves so the cell membrane pulls away from the cell wall. It happens when a plant cell is placed into a hypertonic solution.
When water leaves a plant cell, the osmotic pressure (turgor pressure) will ______________.
The substance that is NOT water is called the ______________.
Down the concentration gradient
During diffusion molecules tend to move ____________________.
The diffusion of water across a selectively permeable membrane.
Glucose enters cells by this.
Going through the tunnel made by integral protein.
Water enters cells by ____________.
Energy for active transport comes from a cell's ___________________.
A cell must EXPEND energy to transport substances using ___________________.
White blood cells engulf, digest, and destroy invading bacteria using ___________________.
The carrier proteins that help is facilitated diffusion are _____________________ proteins.
Diffusion, osmosis, simple diffusion, facilitated diffusion, ion channels
Kinds of passive transport.
Endocytosis and exocytosis both create a small pocket called a ________________.
Carbohydrates that are attached to a phospholipid are called ________________.
Carbohydrates that are attached to a PROTEIN are called _________________. They indicate the type of cell.
Move into the cell
Placing an animal cell in a hypotonic solution will cause water to _________________.
Golgi bodies use ___________ to release large molecules from inside to outside the cell.
The cell organelles that burn glucose and make energy for active transport are the ___________________________.
During _________________ diffusion, carrier proteins (integral proteins) act as a tunnel from one side of the membrane to another.
An _________________________ is a membrane protein that helps move molecules across a cell membrane.
A _______________________ forms whenever there is a difference in concentration between one place and another.
When molecules move from high to low concentration along a concentration gradient we say they are moving _______________ the gradient.
_______________ is caused by water inside a plant cell pushing against the cell wall.
The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is called _____________________.
White blood cells use ____________________ to engulf and destroy bacteria that the glycoproteins recognize as "not self".
The swelling and bursting of animal cells when placed in a hypotonic solution is called ______________________.
Proteins (like carrier proteins) that stick into the cell membrane and span all the way through are called ___________ proteins.
Proteins which are part of the membrane but do NOT span all the way through are called __________________.
Main component of the cell membrane.
Prevents close packing of the lipids.
Transport ions through the membrane
The unequal distribution of particles.
The water pressure in cells.
The water pressure in PLANT cells.
Process where the cell membrane pulls AWAY from the cell due to water loss.
High to low concentration.
The diffusion of water.
"needs a passageway" and uses proteins.
