| Question or Term | Answer or Definition |
| Cytology | Study of cells |
| Dutch Scientist who discovered cells in the 1600s | Antonie Van Leeuwenhoek |
| What did Antonie think cells looked like | jail cells |
| organelles | All the components or "little organs"that make up a cell are called |
| cell membrane | membrane or skin that covers a cell |
| phospholipid bilayer | what the cell membrane consists of |
| The Lipid layer is | hydrophobic |
| The Phosphate groups are | hydrophilic |
| cell membrane function | the ability to allow certain substances to pass through but not all, also known as semi-permeable |
| cell wall | Extra layer of protection around a plant's cell |
| Made of cellulose, which are long strings of glucose molecules | cell wall |
| Cell wall function | strength and support or skeletal framework for the plant cell |
| softwoods are | Trees that have thin cell walls and grow quickly |
| hardwoods are | Trees that have thick cell walls and grow slowly |
| cell organelle that functions like the brain is | the nucleus |
| Some nuclei have a membrane known as | nuclear membrane or nuclear envelope |
| Eukaryotes | organisms that do have a nuclear membrane or envelope (Eu=do) |
| Prokaryotes | organisms that have no nuclear membrane or envelope (Pro=No) |
| prokaryotic organism example | bacteria |
| Chromosomes (colored bodies) | The structures within the nucleus of a cell which hold the instructions for the cell |
| Chromo | colored |
| -somes | bodies |
| The number of & information on each chromosome is | specific for each living thing |
| Chromosomes consist of smaller subunits or "recipes" known as | genes |
| Genes code an organism's | features, traits, or characteristics |
| Mitochondrion function | the cell's power plant |
| What fuels the Mitochondrion | glucose |
| C6H12O6 | chemical formula for glucose |
| Mitochondrion are shaped like | beans |
| Cristae | Inner membrane of the mitochondrion |
| Respiration | the process whereby glucose is converted into energy in the form of ATP in the mitochondrion |
| ATP is the abbreviation for | adenosine triphosphate |
| In the presence of oxygen, one glucose molecule will yield | 38 ATPs |
| With no oxygen present, one glucose molecule can only yield | 2 ATPs |
| aerobic respiration | respiration in the presence of oxygen |
| anaerobic respiration | respiration not in the presence of oxygen |
| The two main uses for ATPs are to allow for | movement and heat production |
