Cellular Transport 🤘🏻 Flashcards
There is a LOWER concentration of solute molecules OUTSIDE of the cell than inside the cell.
Hypotonic solution
There is the SAME concentration of solute molecules outside the cell as inside
Isotonic solution
The SWELLING AND BURSTING of animal cells when water enters happens when a cell is placed in a
Hypotonic solution
What organelle {that plants have and animals don’t} keeps plant cells from bursting in this condition?
Cell Wall
The SHRINKING of plant cells when water leaves so the cell membrane pulls away from the cell wall or shrinking of animal cells happens when a plant cell is placed in a
Hypertonic solution
Cells stay the same size when placed in a ________ solution because of the amount of water leaving the cell is the same as the amount of water entering.
Isotonic
The substance that dissolves make a solution is called the ______.
Solute
During diffusion molecules tend to move ____.
Down
When the concentration of solute inside & outside the cell is the same, the cell has reached ___________________.
Dynamic equilibrium
The diffusion of water across a selectively permeable membrane is called _______.
Osmosis
Energy from active transport comes from a cell’s ____________.
Mitochondria
______ transport requires energy from ATP to move substances across membranes.
Active
All of the following are kinds of transport EXCEPT A. Diffusion B. Facilitated diffusion C. Osmosis D. Ion channels
D. Ion channels
When molecules move DOWN the concentration gradient it means they’re moving from…
An area of high concentration to an area of low concentration
Active transport requires ______ to move molecules across the membranes.
Energy
___ is the molecule that provides the energy for active transport.
ATP
_________ moves oxygen and carbon dioxide molecules from a high concentration to a low concentration across membranes.
Diffusion
The cell organelle that burns glucose and provides ATP for active transport are the _____________.
Mitochondria
Water moves across membranes by _______.
Osmosis
A small membrane sac used to transport substances during exocytosis and endocytosis= _______.
Vacuole
_______ transport does NOT REQUIRE energy.
Passive
A cell is placed in ________ solution neither swells or shrinks because the concentration of molecules outside of the cell is the same as inside.
Isotonic
A concentration ________ forms whenever there is a difference in concentration between one place and another.
Gradient
_______ pressure is cased by water inside a plant cell pushing against the cell wall.
Osmotic
There is a greater concentration of solute molecules OUTSIDE the cell than inside
Hypertonic solution
