| cells | all organisms are made of these |
| unicellular | an organism that can carry out life functions within just a single cell |
| multicellular | an organism that has specialized cells that help each other survive |
| develop | changes an organism goes through simple to more complex |
| endoplasmic reticulum | network of passages that transport proteins and make hormones |
| cytoplasm | gel-like substance where all organelles are found |
| nucleus | organelle that holds the DNA of the cell |
| vacuole | stores materials in the cell; rather large in plants |
| ribosomes | protein "factories" |
| golgi body | package and ship cell parts |
| mitochondria | converts sugar into usable energy for the cell (power house) |
| chloroplast | creates food molecules with energy from the sun |
| cell membrane | controls what get in and out of a cell |
| cell wall | made of cellulose and gives a cell a rigid shape and structure |
| flagella | whip like apendage that propels a cell through liquid |
| pili | allow bacteria to attach to things or each other |
| chromatin | long strands of nucleic acids that make up the DNA |
| nucleoid region | area in a prokaryote where the DNA is found |
| prokaryote | an organism that does not have a nucleus |
| eukaryote | organism that has a nucleus |
| homeostasis | a constant process where organisms keep their internal environment stable despite changes to their outside environment |
| organelle | a special structure in a cell that has a specific job to do |
| capsule | a layer of material that protects bacteria from its outside environment |
| nucleolus | makes ribosomes inside the nucleus |
| nuclear pores | tiny openings in the nucleus that allow materials to enter and exit the nucleus |
| lysosomes | organelles that break down large molecules and recycle cell parts |
| microtubule | long strands of protein that help support a cells structure |
| cytoskeleton | network of microtubules that help shape the cell |
