Organization, Homeostasis, Reproduction, Evolution, Responsiveness, Metabolism, Growth & Development, Heredity

1. What is Biology? The study of life.

1. What is the difference between a eukaryotic cell and a prokaryotic cell? Prokaryotic Cells - Do not have a nucleus, simple cells with no membrane bound organelles, usually bacteria cells. Eukaryotic Cells – Have a nucleus and membrane bound organelles. Very complex. Large, includes plant and animal cells.

1. What are the structures in eukaryotic cells that carry out specific activities? Organelles

1. The term organic in science means which element is present? Carbon.

1. What does DNA do? Contains genetic information.

1. What does RNA do? Helps with protein synthesis.

1. Describe the difference between a plant cell and an animal cell:

10. What is the correct order of organization of structures in living things? Cells, Tissues, Organs, Organ Systems, Organism

11. Name the three parts of the Cell Theory: All things are made of cells. Cells are the basic unit of structure and function. All cells come from other cells.

12. What are enzymes and what is their function? Enzymes are a type of protein that decrease activation energy in a reaction and increases the reaction rate.

13. What is a monosaccharide? One sugar ex: fructose, galactose, ribose.

14. What is a disaccharide? Two sugars put together ex: sucrose & lactose.

15. What is a polysaccharide? Three or more sugars bound together by links ex: cellulose, insulin, starch.
