Example: pasta, rice
Lipids

Example: butter, copholesterol
Soluble
Able to be dissolved
Cellular Respiration

Ex. Humans, animals, plants
Cilia
Little hair like structures on the outside of cells that move materials or the cell around
Diffusion
Process of materials moving in and out of the cell without using energy
Active transport
Process of moving materials in and out of the cell with energy
Homeostasis
