Cell-The basic unit of structure and function in living things

Cell wall- A rigid layer of nonliving material that surrounds the cells of plants and some other organisms

Chloroplasts- a structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food

Chlorophyll- a green pigment found inside of the chloroplasts

Nucleus- The “control center” of a cell that directs the cell’s activities; contains the chemical instructions that direct all the cell’s activities and determine the cell’s characteristics “the brain”

Ribosome- (ribs=meat, meat=protein) A tiny structure in the cytoplasm of a cell where proteins are made

Vacuole-“storage tank”, a water-filled sac inside a cell that acts as a storage area

Mitochondria- “powerhouse”, Rod-shaped cell structures that produce most of the energy needed to carry out the cell’s functions

Cytoplasm-The region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes); contains a “gel-like” material and cell organelles

Cell membrane/Plasma Membrane- “screen door”, the outside boundary of a cell; controls which substances can enter or leave the cell

Golgi Apparatus/Golgi Bodies- “UPS”, a structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell

Lysosomes- “recyclers”, small round cell structure that contains chemicals that break down large food particles into smaller ones

Endoplasmic reticulum-“transporter”, 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

Cell Theory-A widely accepted explanation of the relationship between cells and living things

Organelle-a tiny cell structure that carries out a specific function within the cell
