What is a primary lysosome?

• A lysosome that has fused with a phagosome

• A lysosome containing hydrolytic enzymes before digestion

• A lysosome that expels waste

What characterizes a secondary lysosome?

• It is only found in plant cells

• It contains only undigested materials

• It results from the fusion of a primary lysosome and a phagosome

• It is smaller than a primary lysosome

What are hetero-lysosomes formed from?
