TermDefinition
Cell membrane A thin structure that surrounds the cytoplasm and nucleus of a plant/animal cell and controls what goes in and out of the cell.
Cell wall Stiff structure outside of the cell membrane of a plant cell that provides strength and support.
Chloroplasts Organelle in the cytoplasm of plant cells that contain chlorophyll that helps make food through photosynthesis.
Chromosomes Located in the nucleus of the cell, it contains code that controls cell and transmits hereditary characteristics.
Cytoplasm The jellylike substance filling the cell that provides energy in the cell and surrounds other organelles.
Endoplasmic Reticulum Organelle that makes lipids and breaks down chemicals that are harmful to the cell and transports the material through the cell.
Golgi bodies Organelle that manufactures and moves material in the cytoplasm of a cell.
Mitochrondria The organelle in the cell that provides energy in the cell by burning sugar to be transferred into ATP.
Nuclear membrane The layer that surrounds the nucleus and moves material in the cytoplasm of the cell.
Nucleus It is the control center for most of the cell's activities.
Ribosomes The organelle in the endoplasmic reticulum that provides protein for the cell.
Vacuole Organelle in the cytoplasm that stores food, water, and wastes in a cell that helps get rid of waste.
Prokaryote They are organisms made of cells without a nucleus or organelles with membrane covering it. The DNA is not in a nucleus.
Eukaryote They are organisms that are made of cells that have a membrane-covered nucleus and membrane-covered organelles. They might be single or multi-cellular.
Mitosis This is when a cell divides into 2 identical cells. They go through 4 steps: prophase, metaphase, anaphase and telophase.
Meiosis This is when a cell splits into 4 daughter cells. Every daughter cell has one half of the chromosomes of the parent cell.
Monomer This is a molecule that bonds with another molecule to make a polymer.
Polymer This is a compound made up of several small, repeating monomers.
Carbohydrates This is an organic compound that contains carbon, hydrogen, and oxygen. Examples of carbohydrates would be glucose, fructose, sucrose, lactose, starch, cellulose, and glycogen.
Lipids These are types of organic compounds that are composed of fats made of carbon,hydrogen, and oxygen. It's in the cell membrane and can store energy well. Examples include fats, oils, and waxes.
Proteins These are organic compounds made of carbon, hydrogen, oxygen, and nitrogen. They are bonded by peptide bonds. An example would be amino acids.
Nucleic acids These are organic compounds that store information in the cell. An example would be DNA. The molecules are made of nucleotides linked into a chain.
