| Question | Answer |
|---|---|
| Cells | The basic unit of life |
| Cell Theory | All living things are composed of cells, cells are the basic unit of structure and function in living things, and new cells are produced from living cells |
| Nucleus | The large membrane enclosed a structure that contains the cell's genetic material in the form of DNA |
| Eurkaryotes | Cells that contain nuclei |
| Prokaryotes | Cells that don't have a nucleus |
| Organelles | Little organs that carry out the cells needs |
| Cytoplasm | The outside portion that encloses the cell |
| Nuclear Envelope | The outside layer of the nucleus composed of two layers |
| Chromatin | DNA bound to protein |
| Chromosomes | Threadlike substances that contain genetic material |
| Nucleolus | Where ribosomes are assembeled |
| Ribosomes | Small particales of DNA and protein |
| Endoplasmic Reticulum | Where lipid components af the cell membrane are assembled |
| Golgi Apparatus | Modify, sort, and package proteins and other materials from the E.R. |
| Lysosomes | Small organelles filled with enzymes |
| Vacuoles | Stores water, salt, proteins, and carbs. |
| Mitochondria | Organelles that convert chemical energy stored in food into useable energy |
| Chloroplasts | Organelles that capture energy from the sunlight and convert it into usable energy |
| Cytoskeleton | The internal organization that supports the structure of the cell |
| Centrioles | Organize cell division |
| Cell Membrane | A thin flexible layer that surrounds the cell |
| Cell Wall | Strong supporting layer of some cells |
| Lipid Bilayer | The compositon of the cell membrane |
| Concentration | The volume or mass/ volume in solution |
| Diffusion | When particles in solution are not equally spread throughout the area |
| Equilibrium | The concentration of the solute is the same throughout the system |
| Osmosis | The diffusion of water through a selectively permeable membrane |
| Isotonic | Two solutions of the "Same Strength" |
| Hyperyonic | One solution is more concentrated than the other |
| Hypotonic | Dilute solution of sugar |
| Facilitated | Helps the diffusion of glucose |
| Diffusion | Hundreds of different protein channels |
| Active Transport | Moving materials in the different direction |
| Endocytosis | The process of taking material into the cell by means of infolding |
| Phagocytosis | Extensions of the cytoplasm surround a particle and package and the vacuole engulfs it |
| Pinocytosis | Tiny pockets form along the the cell membrane, fill with liquid and pinch off to form vacuoles in the cell |
| Exocytosis | Many cells also release large amounts of material from the cell |
| Cell Specialization | Cells throughout the organism can develop in different ways to perform different tasks |
| Tissue | A group of similar cells that perform a certain function |
| Organ | Many tissues work together to make a organ |
| Organ System | A group of organs that work together to perform a specific function |
