What is Carbon
a subatomic particle that is negatively charged
What is an electron
every form of life is composed of these compartments.
What is the cell?
the phospholipid bilayer that separates the cell from its environment
What is a the plasma membrane?
the movement of any substance from higher concentration to a region of lower concentration
What is diffusion?
A type of lipid that makes up the plasma membrane
What is a phospholipid
The fundamental unit of matter
What is an atom
A type of cell that does not contain a nucleus.
What is a prokaryote?
a rigid structure made of cellulose that is found in plant cells but not animal cells.
What is a cell wall
The movement of water from a region of low solute to high solute concentration.
What is osmosis?
a biological molecule that does not readily dissolve in water
What is lipid?
The type of bond that is found in salts
What is an ionic bond?
The compartment in which eukaryotes store their genetic information.
What is a nucleus?
the part of the phospholipid that is hydrophilic

What is a semipermeable membrane?
They most stable type of chemical bond
What is a covalent bond

What is an acid?
Tiny organs within the cells that carry specialized functions.
What are organelles?
A patching agent found in the plasma membrane that also helps with flexibility
What is cholesterol

What is active transport
The storage carbohydrate made in plants
What is starch
The unequal sharing of electrons between two atoms.
What is electronegativity?
organelles that break down worn out cellular structures or foreign materials that enter the cell.
What is a lysosome?
the conceptualization of the plasma membrane being flexible and consists of many different types of proteins.
What is the Fluid Mosaic Model?
the usage of transport vesicles to transport material from the interior of the cell to the plasma membrane, and then released into the environment.
What is exocytosis?
