For example, when the pH in the cells environment drops, the H + ions surging into the cytosol can be transferred to a vacuole in order to keep the cytosol's pH constant. citation In animals, vacuoles serve in exocytosis and endocytosis processes. Source: Internet
In plant cells, vacuoles cover anywhere from 30% to 90% of the total cell volume. citation Most mature plant cells contain one large central vacuole encompassed by a membrane called the tonoplast. Source: Internet
Animal vacuoles are smaller than their plant counterparts but also usually greater in number. Source: Internet
For example, developing cells in the meristems contain small provacuoles and cells of the vascular cambium have many small vacuoles in the winter and one large one in the summer. Source: Internet
Ions that are absorbed into tissues are sequestered in cell vacuoles. Source: Internet
Larger vacuoles encircling neurons, vessels, and glia are a possible processing artifact. Source: Internet
