Organelle Functions
This organelle controls all the other organelles in the cell
The Nucleus
Transport that does not require energy
What is passive transport
Movement of molecules across a cell membrane that requires energy
What is active transport
This solution has an equal number of solutes in and outside the cell.
What is isotonic
Osmosis is considered this type of transport.
What is passive transport?
This organelle is responsible for cellular respiration, which is when food is turned into energy
Mitochondria
The movement of molecules from high concentration to low concentration
What is diffusion?
Active transport that keeps sodium from building up in the cell.
What is a sodium?
Solution with high solute concentrations on the outside of the cell, making a cell shrink.
What is hypertonic?
Facilitated diffusion is the movement of ___________ down the concentration gradient using __________
molecules (or particles, or solutes).... proteins (or channel proteins)
This organelle, only found in animals, aids in cellular division
Centrioles
Diffusion of water
What is osmosis
Molecules that are too large to move in the cell are transported through this process
What is endocytosis?
Solution with a low solute concentration on the outside, making the cell swell.
What is hypotonic?
Active transport refers to particles moving from ______ to _______ concentrations
Low to high
This organelle contains enzymes that are used to break down waste and other items the cell no longer needs
Lysosomes
The movement of molecules across a membrane with the help of a protein. Does not require energy
What is facilitated diffusion?
Vesicles transport wastes out of the cell through this process.
What is exocytosis?
After diffusion or osmosis a cell will be in this state
What is homeostasis?
Differentiate between pinocytosis and phagocytosis
Pinocytosis moves small molecules and phagocytosis moves large molecules. Cellular "eating" vs Cellular "drinking"
If you were to compare a cell to a city, what organelle would be the transport company?
Golgi Apparatus
These types of molecules move easily through a cell membrane
What are small, non-polar molecules
During active transport molecules move in this direction across the cell membrane.
What is from low concentration to high concentration?
If the volume of a cell increases when it is placed in a solution, that solution is said to be ______________ to the cell.
Hypotonic
Differentiate between endocytosis and exocytosis
Endocytosis moves molecules into the cell exocytosis moves molecules out of the cell
