What does a vacuole do?

Answer 1

Vacuoles are membrane-bounded compartments within some eukaryotic cells that can serve a variety of secretory, excretory, and storage functions. Vacuoles and their contents are considered to be distinct from the cytoplasm, and are classified as ergastic according to some authors (Esau, 1965). Vacuoles are especially conspicuous in most plant cells.

In general, vacuole functions include:

removing unwanted structural debris surrounding the cell
sequestering materials that might be toxic to the cell
containment of waste products
maintaining internal hydrostatic pressure or turgor within the cell
maintaining an acidic internal pH
storing small molecules
exporting unwanted substances from the cell.
enabling the cell to elongate rapidly or otherwise alter relative cell size.
Vacuoles also play a major role in autophagy, maintaining a balance between biogenesis (production) and degradation (or turnover), of many substances and cell structures. They also aid in destruction of invading bacteria or of misfolded proteins that have begun to aggregate within the cell. Autophagy is especially prominent in insects that undergo complete metamorphosis; for example, larval tissue is recycled to become appendages in an adult insect

Answer 2

The main function of vacuole is stores food and other chemical substances . Vacuoles in plant cells are big and abundant .But in human cells vice versa means there are not much of them and they are quite small or we can say none in human cells.

Answer 3

For starters, it's a cheap and easy way for the cell to store water - which helps give the cell structure by providing pressure (that's why plants wilt when they don't have enough water, the vacuole is depleted, and the cells become flaccid) It also is a place where metabolites are stored (some plants store toxins in their vacuoles that are only released when the plant is damaged, ie. chewed on by an animal) It's like the cell's junk drawer. It keeps things there that it doesn't want right now, whether it wants them later - like metabolites, or if it doesn't want them at all - like waste.

Answer 4

Vacuole Storage Space For

Answer 5

The biggest vacuole is present in plant cells. It takes in waste, nutrients (water and CO2), and glucose. That's why a plant stands upright.

Answer 6

in a plant stores water

in an animal stores waste

Answer 7

It stores starch mostly. It can be found in abundance in plants, but very little or none in animals.

Answer 8

Stores food water and other particles

Answer 9

Storage space for cellular substances, i.e., food,wastes,water,poisons.
