1. What defines liv- Living things are made up of basic units called cells, are based on a universal
ing organisms sep- genetic code, obtain and use materials and energy, grow and develop, repro-
arate from non-liv- duce, respond to their environment, maintain a stable internal environment,
ing things? and change over time
2. Discuss the scien- Involves observing and asking questions, making inferences and forming hy-
tific method and potheses, conducting controlled experiments, collecting and analyzing data,
its use in acquiring and drawing conclusions
knowledge.
3. What are atoms? The basic units of matter
4. What are atoms Made of protons, neutrons, and electrons
made of?
5. How do we define By looking at the number of protons in the nucleus
and recognize one
type of atom from
another?
6. How are atoms held They attach to other atoms to make a covalent bond. If there are 4 attached
together into mole- atoms, it is a double bond. If there are 6 attached atoms, it is a triple bond
cules?
7. Discuss the struc- Van der Waals forces are a slight attraction that develops between oppositely
ture and function charged regions of nearby molecules. They aren't as strong as ionic and cova-
of the major types lent bonds, but they hold molecules together, especially the large ones
of large molecules
found in living or-
ganisms.
8. Water is a polar molecule and it is able to form multiple hydrogen bonds

ties of water benefit and other polar molecules
living organisms?
10. What are the two Prokaryotic and eukaryotic cells
different types of
cells found in living
organisms?
11. How are prokary- Prokaryotic cells don't have a nucleus and eukaryotic cells have a nucleus, where
otic and eukaryotic they separate the genetic information from the rest of the cell
cells different?
12. Organelles Many of the structures in cells; called "little organs"
13. Cytoplasm The portion of the cell outside the nucleus
14. Vacuoles Store materials like water, salts, proteins, and carbohydrates
15. Lysosomes Break down lipids, carbohydrates, and proteins into small molecules that can be
used by the rest of the cell. They are also involved in breaking down organelles
that have outlived their usefulness
16. Cytoskeleton Helps the cell maintain its shape and is also involved in movement
17. Microfilaments Threadlike structures made up of a protein called actin
18. Microtubles A hollow structure made up of proteins known as tubulins
19. Centrioles
