| Cell Theory | Idea developed over hundreds of years, all organisms are made of cells, cells are the basic unit of life and cells come from other cells. |
| Magnification | Using lenses to enlarge the view of small objects. |
| Cell Membrane | Controls what goes in and out of the cell. Protection. |
| Cytoplasm | Material inside cells that supports cells. |
| Cell Wall | Found only in plants, gives them their unique shape. Protection. |
| Organelle | Name given to the tiny structures in the cytoplasm of eukaryotic cells. |
| Nucleus | Organelle that controls the cell. Contains DNA. |
| Chloroplast | Organelle that performs photosynthesis. Found only in plants. |
| Prokaryotic | Any cell without membrane bound organelles. EX. Bacteria |
| Eukaryotic | Cell with membrane bound organelles (nucleus). You are eukaryotic. |
| Cell | The smallest unit capable of performing life functions. |
| Tissue | A group of similar cells working together. |
| Organ | Made up of two or more tissues working together. |
| Organ System | A group of organs performing together. |
| Organism | The highest level of organization. A living creature. |
| Active Virus | A virus that infects a host cells causing it to create more viruses. |
| Latent Virus | A virus that attachs a host cell but does not cause the host cell to duplicate viruses immediately. |
| Compound Light Microscope | Uses lenses and light to magnify living and non-living objects. |
| Electron Microscope | Uses a beam of electrons to greatly magnify preserved specimins. |
| Mitochondrion | Organelle that transform sugar into energy. |
| Golgi Body | Organelle that packages substances for delivery outside the cell. |
| Vacuole | Used for short term storage of water and other substances. |
| Vaccine | Weakened particles to stimulate the immune system. |
| organelles | tiny structures that carry out functions in a cell |
| cell wall | rigid layer of nonliving material that surrounds plant cells |
| cell membrane | controls what comes in & out of cell |
| nucleus | cell's control center |
| nuclear membrane | controls what gets in & out of the nucleus |
| cytoplasm | clear, thick gel-like fluid |
| mitochondria | powerhouse of the cell |
| chloroplasts | capture sunlight & produces food for the cell |
| vacuoles | sacs which store food, water, waste, & other materials for cells |
| cell theory | generalization that all living things are composed of cells, and that cells are the basic unit of structureand function in all living things |
| experimental group | "guinea pigs" -- the real test group in an experiment |
| observation | something noted in an experiment or noticed about the world around you |
| control group | part of an experiment treated "normally" -- used to compare experimental results |
| hypothesis | untested idea, an educated guess |
| inference | a conclusion or explanation based on observations made about something |
| scientific method | steps often used in solving problems in science (can be helpful in solving any problem) |
| experiment | used to test a hypothesis |
| procedure | something DONE in an experiment |
| science | search for the true nature of the world and how it works based on our observations of it |
| quantitative observation | Observation using measuring tools and numbers. |
| qualitative observation | Observation made using the senses. |
| purpose | Why the experiment was developed? |
| variable | What is changed in an experiment. |
| independent variable | the variable the scientist changes. ex how much water a plant gets |
| dependent variable | the variable that changes in response to the independent variable. ex the plant gets taller |
| Chlorophyll | uses light energy to split water molecules during photosynthesis |
| unicellular | Composed of one cell. |
| multicellular | Organism with more than one cell. |
| atom | Smallest unit of matter |
| proton | Found in the nucleus of an atom, positive charge. |
| neutron | Found in the nucleus, neutral charge. |
| electron | Found in energy levels outside the nucleus of an atom. |
| atomic number | Number of protons. |
| atomic mass | Number of protons added to neutrons. |
| periodic table | Chart of the elements. |
| compound | When two or more elements are chemically joined. |
| solution | Mixture that will not seperate. |
| suspension | Mixture that will seperate. |
