Prokaryote
The largest organelle in the cell, which contains genetic information and controls cell function.
What is a nucleus?
This organelle includes digestive enzymes which help cells to break down food and waste.
Lysosomes
The basic unit of a chemical element
Atom
A single celled organelle where photosynthesis happens?
Chloroplast
Something made up of a single cell?
Unicellular
A change of the DNA in an organism that results in a new trait.
What is Mutation?
Segments of DNA that encode for proteins.
What are genes?
Building block of monomers and lipids

Cytoplasm
During the frog disection, we had to cut through ______________ in order to discover the frog's organs?
Tissue
Small chemical unit that can join together with other small units to form larger units is called polymers.
Monomers
This term describes a mechanism that is regulatory and contributes to maintaining a state of equillibrium.

What is the study of new species which have developed from preexisting species over time?
Evolution
When we study plants or animals we are studying what form?
Biotic
What is similar to a storage unit which stores water, salts, proteins and carbohydrates in a cell?
Vacuole
The place where the enzyme and the substrate fit together.
Active site
The movement of substances across the plasma membrane from an area of high concentration to an area of low concentration without the need of energy.
What is passive transport?
