Vacuole in Plant Cells

Vacuole in Plant Cells- Vacuole is a membrane-bound storage organelle of cells, which helps in regulating the turgor pressure of plant cells. In plant cells, there can be more than one vacuole. However, the vacuole has a larger form than the others, which stores all kinds of chemical compounds. Vacuole also helps in digestion and excretion of intracellular molecular complex waste products of plant cells.

Vacuoles in plant cells
Vacuole contained either in animal cells and plant cells, but the cells appear larger plants and clear, especially in cells that already older.Vacuole in plant cells surrounded by a single membrane called tonoplas. Vacuole of plant cells generally contains: water, phenol, anthocyanin and proteins, glycosides, organic salts, proteins, tannins (tannin substances), etheric oils (such as the Jasmine on jasmine, Roseine on Zingiberine rose on the ginger), alkaloids (such as caffeine, quinine, nicotine, Likopersin etc.), enzymes, starch grains. In some species the known contractile vacuole and non-contractile vacuole. Some scientist do not include the vacuole as a cell organelle. These objects can be seen with the ordinary light microscope. Membrane barrier between the cytoplasmic vacuoles called Tonoplas vacuole.

Vacuole in Plant Cells

Vacuoles structure

The central vacuole of plant cells is a multipurpose compartment. It can keep the important organic compounds, such as deposited proteins in the vacuole of seed. Now a major repository of plant cell is anorganic ions, such as potassium and chloride.

Vacuoles function

Many plant cells use their vacuoles as a disposal site for metabolic by-products that would endanger if the cells accumulate in the cytosol. Some vacuoles contain pigments that color the cells, such as red pigment and blue petals to attract insects to pollinate the flowers.

Vacuoles also can help protect the plant against predators with toxic compounds that contain or disliked for the animals. The vacuoles have a major role in cell growth of plant, which enlarge as they absorb water vacuoles, allowing the cells to become larger with minimal investment in new cytoplasm. Cytosolic often occupies only a thin layer between the central vacuole and the plasma membrane, so that the ratio of the surface of the plasma membrane to the cytosol large volume, even for large plant cells.
