Question

function of vacuole in deatil for 3 marks

Answer 1

Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.

Answer 2

Vacuoles are present in all plant and fungal cells. Animal cell vacuoles are smaller in size. Most bacteria and animal cells have vacuoles.

Functions of vacuoles are :

it maintains turgor pressure within the plant cells.
it acts as a storage organelle.vacuoles in many cases contain chemicals which would otherwise react with the cytosol.
in plants vacuoles help in maintaining the cytoplasmic pH of the cell.
in certain fungi ( yeast ) vacuoles are involved in osmoregulation, degradative processes and storing amino acids.
in some Cyanobacteria, vacuoles contain gases ( gas vacuoles ) that help in controlling their buoyancy.
in animal cells vacuoles are involved in the containment, transport and disposal of some proteins and lipids to the extra cellular environment of the cell.
