Lysosomes are vesicles that contain digestive enzymes. They are only present in animal cells. They function as part of the cell’s recycling system and can also help initiate cell death. When a cell needs to recycle large molecules, lysosomes release their enzymes to break down these bigger molecules into smaller ones.
Are vesicles found in all cells?
Secretory vesicles include synaptic vesicles and vesicles in endocrine tissues. Transport vesicles move molecules within the cells. All cells make proteins and require them to function. … Vacuoles are vesicles that contain mostly water.
Where is the vesicle located and what is its function?
In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion (exocytosis), uptake (endocytosis) and transport of materials within the plasma membrane.
