Cytoskeleton
Cytoskeleton
A web of protein fibers found in eukaryotic cells that support the cell.
What does the cytoskeleton do?
It helps the cell move, keep it’s shape, and organize it’s parts.

Lysosome
A special type of vesicle that contains specific enzymes that break down large molecules, digest food particles to provide nutrients, and digest old or damaged cells

Lysosome
Central Vacuole
Stores water, ions, nutrients and wastes.
Determines if the plant has rigidity or if it wilts
