LYSOSOMES - Surrounded by a single membrane.- Derived (buds of) from Golgi apparatus.- Contains degradative enzymes for digesting foreign bodies,

cellular wastes and other toxins.

PRIMARY LYSOSOME - is a membrane bounded sac that buds off from the GA apparatus

SECONDARY LYSOSOME - is a primary lysosome that fuses/ phagocytosis with any solid material in the cell (e.g. organelle or

bacteria)

Lysosomes

• Contain digestive enzymes

• Break down old cell parts

Cytoskeleton Functions• Support and shape

cell• Anchor many

organelles• Move substances from

one part of the cell to another

• Enable cell division• Enable cell movement

CYTOSKELETON -A dynamic internal framework/ scaffolding

FUNCTION;1 .Contributes to cell shape

2 .Coordinates cytoplasm and its components )e.g. act in cell division, muscle movement(
