Cell Notes Cell Theory 1. All living things are made of cells. 2. Cells are made by other cells. 2 Types of Cells • Prokaryotic Cells –have no nucleus (Bacteria) • Eukaryotic Cells – Cells that have a nucleus. (plants, animals, fungi, & protists) Nucleus – holds the DNA in the center of the cell Eukaryotic Cells viewed with a microscope Organelles Organelles – like organs in your body, these small parts of the cell do all the jobs for the cell Nucleus • Controls all of the functions of a cell using DNA • It is in the center of the cell. Cytoplasm • The jelly like substance that fills the cell it holds everything in place. Cell Membrane • Covers and protects the cell. Decides what enters and leaves the cell. Mitochondria • Breaks down your food to make energy. Ribosomes • Makes proteins. Endoplasmic Reticulum E.R. • Transports (carries) things in a cell. • Folds proteins to finish them. Lysosomes • Break down waste (garbage). Golgi Bodies • Packages protein made by ribosomes Plant cells also contain: • Cell Walls • Chloroplasts • Large Vacuoles Plant Cells: Cell Wall • Cell Wall surrounds cell and protects it. Makes a plant cell hard and straight. Chloroplasts • Used in photosynthesis to make food for the plant. Makes the plant green. Vacuoles • Stores water. Plants have bigger vacuoles than animal cells do. Test yourself: Animal Cell Test yourself – Plant cell
