Nucleus Control center Location: inside the cell, near the center Cell Parts and Functions Nucleolus (Nucleoli) Makes ribosomes Location: inside the nucleus (dark spot) Nuclear Membrane Protects nucleus Lets things in/out of nucleus (pores) Location: around nucleus cell Cell Parts and Functions Mitochondria Makes energy/powerhouse Location: in cytoplasm Golgi Bodies/Apparatus Packages and secretes (gets rid of) waste Location: in cytoplasm Mitochondria GOLGI APPARATUS Cell Parts and Functions Endoplasmic Reticulum (E.R.) Transports materials and sends messages to all parts of the cell Two types: smooth and rough (has ribosomes) Location: attaches from cell membrane to nuclear membrane Rough E.R. Cell Parts and Functions Ribosome Makes proteins Location: in cytoplasm or Attached to E.R. Vacuole Stores food and water Location: in cytoplasm Vacuole Cell Parts and Functions Lysosome Contains digestive enzymes Destroys bacteria, old cell parts… Location: in cytoplasm Centrioles Helps the cell to divide Location: in cytoplasm Cell Parts and Functions Cytoplasm Gel-like substances, holds all Organelles in cell Location: in cell Chromatin/Chromosomes Contains genetic information/traits Location: in nucleus Cell Parts and Functions Cilia Short hair-like projections Used for movement Location: outside of cell Flagella Long whip-like tail Used for movement Location: outside of cell FLAGELLA Cell Structures and Functions Chloroplast Traps suns energy and Makes food Location: in plant cells Cell Wall Cell Wall Protects and supports plant Cells Prevents water loss Cellulose Location: outer layer of plant cells CYTOSKELETON Function: Support structure of cell and transport materials/organelles throughout the cell. Made of Microtubules (thin hollow cylinders) and Microfilaments (thin solid cylinders) Location: Inside the cell CYTOSKELETON Cell Structures and Functions Plastids Stores extra food in Plant cells Location: in plant cell More info on cell project http://www.cellsalive.com/ Plant vs. Animal Cell ocular Body tube Revolving nose piece
