Vacuole is a fluid filled structure found in cells of the plants, certain animals, protists, fungi, bacteria etc. Vacuoles found in plant cells are larger than that in animal, protist, fungal, and bacterial cells. The vacuole inside a plant cell stores water. It also helps to maintain the turgor pressure of the cell. The functions of the vacuole include isolating materials that might be harmful to the cell
, maintaining an acidic internal pH
, supporting the plant structures such as leaves and flowers.
Operons afford the organism the opportunity to
simultaneously regulate transcription of multiple genes, whose products are
active in the same process. Operons lead to the synthesis of groups of functionally
related enzymes, usually from a single mRNA transcript hence makes regulation of
the genes highly efficient.
