General Function: What To Do With Your Lysosome
Lysosmes are a breakdown organelle
They break down food vacuoles (in pro=sts)
Recycle damaged organelles or small amounts of cell fluid (in animal cells)
Mostly found in white blood cells
Allows cells to renew themselves

How To Use Your Lysosome: Digesting Food
1.

Food Vacuoles Enter Cell
Lysosome fuses with Food Vacuole
Diges=ve enzymes break down food and release nutrients into cell

How To Use Your Lysosme: Recycling Organelles
Vesicle containing damaged organelle or cell fluid enters cell
Fuses with vesicle
Breaks down damaged organelle or cell fluid Organic molecules can be reused

Parts and their Functions: What’s In Your Lysosome
Each lysosome has many types of diges=ve enzymes
Different types of enzymes break down different things
Membrane protects cell from enzymes and acidic environment

Structures and their Functions: Assembling Your Lysosome
Structure of lysosomes shows compartmentaliza=on
Lysosomal membrane surrounds a compartment with an acidic environment for diges=ve enzymes
Separated from the rest of the cell

Break down damaged organelles
Recycling centers break down used paper, glass, etc.
Cell can reuse parts
Recycling centers use recycled materials to make new things
