1.3.1.8 Vacuoles

Vacuoles are large membranous sacs; vesicles are smaller. Vacuoles are often used to store materials used for energy production such as starch, fat, or glycogen. Plant cells often contain large vacuoles filled with water. Vacuoles and vesicles also transport materials within the cell and form around particles that enter by endocytosis .
