What are examples of vesicles?

Examples of vesicles include secretory vesicles, transport vesicles, synaptic vesicles and lysosomes. Vacuoles are membrane-bound organelles that can have secretory, excretory, and storage functions. They are usually larger than vesicles.

Why are vacuoles and vesicles important?

Role. Vesicle: Vesicles are involved in metabolism, temporary storage of food and enzymes, transport molecules and buoyancy control. They also serve as chemical reaction chambers. Vacuole: Vacuoles are involved in storing substances, mostly water, contributing to the structural support to the cell.

Is a vesicle a plant cell?

As for mammals, plant cells contain the three major types of vesicles: COPI, COPII, and CCV and the major molecular players in vesicle-mediated protein transport are also present. However, plant cells generally contain more isoforms of the coat proteins, ARF GTPases and their regulatory proteins, as well as SNAREs.
