Vacuoles, vesicles, lysosomes, and perixosomes

What are vacuoles mainly composed of?
	1.	pectins
	2.	polysaccharides
	3.	phospholipids
	4.	peptidoglycans

The difference between vacuoles and vesicles is based on
	1.	size
	2.	composition
	3.	number
	4.	contents

The function of a contractile vacuole is to
	1.	pump excess water out of the cell
	2.	prevent poisons from entering the cell
	3.	destroy old organelles which are no longer needed
	4.	store food particles for later use

The two ways in which lysosomes and peroxisomes are similar is that they
	1.	are structurally similar to vacuoles and contain enzymes
	2.	digest food particles and perform respiration
	3.	neutralize hydrogen peroxide and perform photosynthesis
	4.	transport proteins and physically protect the cell

Lysosomes are sometimes called "suicide sacs" because
	1.	they randomly destroy healthy organelles without warning
	2.	their only function is to kill the cell under certain circumstances
	3.	if they are broken, their contents can destroy the cell
	4.	they often destroy themselves

Peroxisomes contain a class of enzymes called
	1.	digestive enzymes
	2.	oxidizing enzymes
	3.	reducing enzymes
	4.	neutralizing enzymes
