Cell: smallest functional and structural unit of all living things
Organism: any living thing
Cell Theory – idea that all organisms are made of one or more cells, cells are the basic unit of all
organisms and cells only come from existing cells
4. Unicellular organisms: made of just one cell
5. Multicellular organisms: made of more than one cell
6. Cell membrane: protective layer that covers a cell’s surface, controls what enters and exits
7. Cytoplasm: fluid inside a cell, is where everything is in the cell, like a factory floor
8. Organelles: structures in cells that perform specific functions
9. DNA: short for deoxyribonucleic acid. Contains instructions for all cell processes
10. Nucleus: organelle in eukaryotic cells that contain the cell’s DNA, acts as the boss of the cell
11. Prokaryotes: organisms without a nucleus
12. Eukaryote: organism with a nucleus

Atoms: basic building blocks of matter
Molecule: two or more atoms held together by chemical bonds
Compounds: molecules made of two of more different atoms
Lipid: chains of fatty acids which are made of hydrogen, carbon and oxygen. Mostly used for energy or
storing energy. Also included in some structures and steroids
5. Protein: large molecule made of chains of amino acids. Used to build and repair body structures and
regulate body processes
6. Amino acids: molecules made of carbon, hydrogen, oxygen and nitrogen atoms. Used to create proteins
7. Enzyme: special proteins used to help chemical processes
8. Carbohydrates: molecules made from carbon, hydrogen and oxygen. Mostly used as an energy source
9. Nucleic acid: made of nucleotides. Carries instructions for making proteins
10. Nucleotides: used to make nucleic acids. Their order tells the order of amino acids needed to make a
protein

Cytoskeleton: network of protein filaments that give shape and support to cells
Mitochondria: organelle where cellular respiration occurs. Powerhouse of the cell.
Ribosome: organelle that uses the DNA’s instructions to make proteins by putting together chains of
amino acids. Like a worker in a factory.
4. Endoplasmic Reticulum: system of membranes that helps production, processing and transport of
proteins and lipids. Like an assembly line and assembly line workers.
5. Golgi Complex: organelle that processes, packages and distributes material. Like a packaging department.
6. Cell Wall: rigid structure around the cell membrane. Provides support and protection. Part of Security
Department
7. Vesicle: bubble-like structures used for storing material. Like storage tanks.
8. Vacuole: vesicle that may contain enzymes, nutrients, water or wastes. Like a large storage tank.
