Cells – Parts and Functions Scientific word for cell parts - ORGANELLE
Cell Wall Found in plants and some microscopic organisms. A strong, stiff outer covering. Used for protection Used to give support to the cell Allows materials to enter and leave the cell
CELL MEMBRANE Found in all living things A thin layer that surrounds and hold the cell together – made of fats and proteins Allows materials to enter and leave the cell Allows for shaper changes due to pressure
CYTOPLASM Watery material found inside the cell but outside of the nucleus Surrounds all the organelles – cell parts “float” around in the cytoplasm
ENDOPLASMIC RETICULUM Passageways or “roads” found throughout the cytoplasm. Materials will travel on theses “roads” to get to their destination. Comes in two types – “rough” and “smooth”
NUCLEAR MEMBRANE Thin layer of material that separates the nucleus from the rest of the cell. Allows materials to enter and leave the nucleus
RIBOSOMES Very important – it is the place where proteins are made for the cell Can be found attached to the Endoplasmic Reticulum ( rough ER) or can be found unattached in the cytoplasm
NUCLEUS The “brain” of the cell – it directs all the cell’s activities and functions Usually the largest organelle in the cell Contains all the information needed for the cell to live and grow
CHROMOSOMES Found inside the nucleus Holds all the information about the cell and what it can do Passes on traits of the cell to a new cell
VACUOLE The storage place of the cell Stores – food for energy, water, and waste materials
