Cell wall
A rigid layer that surrounds the cells of plants and some other organisms
Cell membrane
It controls which substances pass into and out of a cell
Nucleus
Acts as a cells control center directing all of the cells activities
Organelles
Tiny cell structures that carry out specific functions within a cell
Ribosomes
Small Grain shaped organelles that produce proteins
Cytoplasm
Fills the region between the cell membrane and the nucleus
Mitochondria
Converts energy stored in food to energy the cell can use to live and function
Endoplasmic reticulum
Or ER is an organelle with a network of membranes that produces many substances
Golgi apparatus
Distributes proteins and materials to other parts of the cell.
Vacuole
Stores food, water, and other materials.
Chloroplast
Captures energy from the sun.
Lysosomes
Contain substances that break down food particles.
Multicellular
Means made of many cells
Unicellular
Single-celled organism
Tissue
A group of similar cells that work together
Organ
Made of different kinds of tissues that work together
Organ systems
A group of organs that work together to perform a major function
Elements
Any substance that cannot be broken down into simpler substances
Compounds
Form when two or more element combine chemically.
Carbohydrates
Energy-rich organic compounds made of the elements carbon, hydrogen, and oxygen
Lipids
Compounds made mostly of carbon and hydrogen, some oxygen
Proteins
Large organic molecules made of carbon, hydrogen, oxygen, nitrogen, and, sometimes sulfur
Enzymes
Speed up chemical reactions in living things
Nucleic acids
Very long organic molecules of carbon, oxygen, hydrogen, nitrogen and phosphorus
