Question | Answer |
Element | Any substance that cannot be broken down into simpler substances. |
Atom | The smallest unit of an element. |
Compound | Two or more elements that are chemicaly combined. |
Molecule | The smallest unit of most compounds. |
Organic Compound | A compound that contains carbon. |
In organic Compound | A compound that doen't contain carbon. |
Carbohydrate | Energy-rich organic compounds, such as sugars, and starches, that are made of the elemnets carbon, hydrogen, and oxygen. |
Protein | Large organic molecules made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. |
Amino Acids | Small molecules that are linked together chemically to form proteins. |
Enzyme | A type of protein that speeds up a chemical reaction in a living thing. |
Lipid | Energy-rich compounds, such as faats, oils, and waxes, that are made of carbon, hydrogen, and oxygen. |
Nucleic Acid | A very large organic molecule made of carbon, oxygen, hydrogen, nitrogen, and phosphorus, that contains instructions that the cells need to carry out all of the function of life. |
DNA | Deoxyribonucleic acid; the genetic material that carries information about an organism and is passed from parent offspring. |
RNA | Ribonucleic acid; a necluic acid that plays an important role in the production of proteins |
Organelle | A tiny cell structure that carries out a specific function within the cell. Some produce energy, build and transport needed materials, and store and recycle waste. |
Cell Wall | A rigid layer of nonliving material that surrounds the cells of plants and some other organisms. It is made of a material called cellulose. |
Cell Membrane | A cell structure that controls which substances can enter or leave the cell. |
Nucleus | A cell structure that contains nucleic acids, the chemical instructions that direct all the cell's activities. |
Chromatin | Material in cells that contain DNA and carries genetic information. |
Cytoplasm | The region between the cell membrane and the nucleus; in organisms without a nucleus , the region located inside the cell membrane. |
Mitochondrion | Rod-shaped cell structures that produce most of the energy needed to carry out the cell's function. |
Endoplasmic Reticulum | 8. endoplasmic reticulum- A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another. |
Ribosome | A small grain-like structure in the cytoplasm of a cell where proteins are made. |
Golgi Body | A structure in a cell thatreceives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell. |
Chloroplast | A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food. |
Vacuole | A water-filled sac inside a cell that acts as a storage area. |
Lysosome | A small round cell structure that contains chemical that breaks down the large food particles into smaller ones. |

Lysosome | A small round cell structure that contains chemical that breaks down the large food particles into smaller ones. |
Cell | The basic unit of structure and function in a living thing. |
Microscope | An instrument that makes smalll objects look larger. |
Compound Microscope | A light microscope that has more than one lens. |
Cell Theory | A widely accepted explanation of the relationship between cells and living things. |
Magnification | The ability to make things look larger than they are. |
Convex Lens | A curved lens in which the center is thicker than the edges. |
