Atomic Theory Part 2
Word | Definition |
---|---|
Conservation of Mass | A principle stating that mass cannot be created or destroyed. |
Compound | A thing that is composed of two or more elements; a mixture. |
Molecule | Can be both an element or compound. |
Covalent Compound | Compound between 2 Non-Metals. |
Iconic Compound | Compound between Metals and Non-Metals. |
Lewis Dot Structure. | Show the way compounds form using Valence electrons. |
Substance | Matter with a fixed composition whose identity can be changed by chemical process but not physical. |
Solution | Homogeneous mixture with elements or compounds mixed on molecular level but not bonded. |
Solute | Substance that dissolves, disappears into another substance. |
Solvent | Substance that dissolves into solute. |
Precipitate | Solid comes out of solution because or chemical or physical change. |
Homogenous Mixture | 2 or more substance evenly mixed but not bonded. |
Heterogeneous Mixture | Mixture where substance is unevenly mixed. |
Vaporization | The process by which matter changes from a liquid state to a gas |
Physical Change | Appearance changes |
Condensation | Change of matter from a gas to a liquid state |
Sublimation | The process by which a solid changes directly into a gas |
Deposition | The act or process of depositing |
Chemical Change | Substance changes |
Law Of Conservation Mass | Conservation of mass: a fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system. |
Cell Theory | States that all organisms are made up of one or more cells, the cell is the basic unit of life ,and all cells come from other cells. |
Cell Wall | Rigid structure that encloses,supports,and protects the cells of plants,algae,fungi,and most bacteria. |
Cell Membrane | Protective outer covering of all cells that regulates the interaction between the cell and the environment. |
Cytoplasm | Constantly moving gelatin like mixture inside the cell membrane that contains heredity material ands is the location of most of a cell`s life processes. |
Ribosome | Small structures on which cells make their own proteins. |
Organelle | Structure in the cytoplasm of a eukaryotic cell that can act as a storage site,process energy,move materials,or manufacture substances. |
Nucleus | Organelle that controls all the activities of a cell and contains heredity material made of DNA. |
Chloroplast | Green,chlorophyll-containing, plant-cell organelle that captures light energy, which is used to make sugar. |
Mitochondrion | Cell organelle where food is broken down,which releases energy. |
Endoplasmic Reticulum | Cytoplasmic organelle that moves materials around in a cell and is made up of a complex series of folded membranes;can be rough(with attached ribosome)or smooth(without attached ribosome). |
Golgi Body | Organelles sort and package cellular materials and transports them within the cell or out of the cell. |
Tissue | Group of similar cells that work together to do one job. |
Organ | Structure,such as the heart,made up of different types of tissues that all work together. |
Organ System | A groups of organs working together to perform a certain function. |
