Cells and all that Jazz H. Smith

Cell Theory: 3 parts Cells are the basic unit of life. All living things are made of cells. All cells come from pre-existing cells

Organelles “organs” of the cell Have special functions within cell

Nucleus Control Center Contains DNA All eukaryotic cells have one

Nucleolus Center of nucleus Creates Ribosomes

Nuclear envelope Surrounds nucleus, controls movement in and out of nucleus

Nuclear Pore Holes in nuclear envelope, allows things to enter and leave nucleus

Mitochondria “Powerhouse” of cell Produces energy (ATP) Membrane bound Has own DNA

Smooth Endoplasmic Reticulum (SER) Transports molecules Detoxification Makes lipids

Rough Endoplasmic Reticulum (RER) Protein alterations Transport of molecules Rough=has ribosomes attached

Ribosomes Protein factories Create proteins Free or attached to rough ER

Golgi Apparatus Packaging of proteins, lipids, and carbs Post office of cell

Vacuole Storage Very large in plant (stores water)

Lysosome Recycling center Contains enzymes for digestion Reuse old cell parts

Vesicle Taxi cab Transports molecules to and from cell membrane

Chloroplast PLANTS ONLY Site of Photosynthesis Contain chlorophyll pigment (green)

Cell Membrane Surrounds cell Barrier, controls what moves in/out of cell Made of aPhospholipid bilayer Semi-permeable

Cell Wall PLANT ONLY Surrounds cell (outside membrane) Protection

Cytoplasm Gel inside cell Surrounds organelles Cytosol: fluid portion of cytoplasm

Centrioles ONLY ANIMAL “midwives” Assist in cell division

Chromatin Condensed DNA Found in nucleus

Microtubule Protein tubes, make up cytoskeleton of cell Support Thick

Microfilaments Thin Make up cytoskeleton Flexible, allow cells to move

Cilia Small hairs for movement Animal only

Flagella Tail-like structure Movement Animal only
