SCIENCE CHAPTER 3

ALL OF THE VOCAB FROM CHAPTER 3!

QuestionAnswer
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.
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.

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.
