Presentation transcript:

A Tour of the Cell: Lysosomes By Olivia Caraballo and Kayley Gibbons

What is A Lysosome? An organelle in the cytoplasm of eukaryotic cells Contain digestive and waste removal enzymes

Structure of a Lysosome Has a single membrane pouch Membrane is composed of phospholipid bilayer Contains enzymes and proteins within Circular structure

Up close and personal with Lysosomes TEM Image of a Lysosome

What does a lysosome do? Main sites of digestion Break down various cells Enables cells to process nutrients Destroys cells after they die

Lysosome fun facts Lysosomes play a part in APOPTOSIS, the death of a cell Apoptosis is the reason your fingers are not webbed When apoptosis fails to occur you have CUTANEOUS SYNDACTYLY, webbing of the fingers or toes

More fun facts Hydrolases- strong digestive enzymes contained in lysosomes in tadpole tails Tails are absorbed Broken down and reused to make legs

_________ is the death of a cell. Cutaneous Syndactyly Apoptosis Hydrolases Tascosis
