A vesicle that contains hydrolytic digestive enzymes is called a
Lysosome
Molecules that can attach, detach, and reattach to actin filaments to produce movement are called:

Select the following which relate to the role of microtubules in a eukaryotic cell. (Mark all that apply)
Organelle movement Cilia and flagella Cell shape
Liver and kidney cells filter and destroy many toxins. As a result they contain high numbers of which type of organelle?
Peroxisomes: Lysosomes are similar to peroxisomes but peroxisomes contain enzymes whose action results in hydrogen peroxide, a toxic molecule.

Thylakoids
Parts of bacteria
capsule gelatinous sheath that surrounds and protects the cell fimbriae short appendages used for attachment flagella long thin appendages used for locomotion
Which organelle receives proteins and lipid-filled vesicles from the endoplasmic reticulum and then repackages them for export in secretory vesicles?
golgi apparatus
Which protein forms microtubules in the cell?
tubulin
