Question

Name the organelles which show the analogy written as under
Storage sacs of the cell ______

Answer 1

Hint: Within the membrane, a storage sac stores salts, minerals, pigments and proteins. The fluid that fills it is called the sap of a cell. It is also packed with cytosol protons that help to sustain an acidic environment within the cell.

Complete answer:
Vacuoles are membrane-bound organelles that are packed with water, both inorganic and organic molecules. In-plant cells are large and centrally located, while they are either small or absent in animal cells. As it stores water, food and waste products, it is also called a storage sac.
The function and importance of vacuoles vary considerably according to the type of cell in which they are found, with far greater prominence than those of animals and bacteria in the cells of plants, fungi and some protists. The functions of the vacuole, in general, include:

1)Isolating contaminants that may be toxic to the cell or a danger to it
2)Containing the results of waste
3)Having water in cells in plants
4)Maintaining hydrostatic internal pressure or turgor inside the cell
5)Holding the internal pH acidic
6)Producing tiny molecules
7)Export of undesirable compounds from cells
8)Requires plants due to the pressure of the central vacuole to support structures such as leaves and flowers
9)Thus, storage sacs of the cell are vacuoles.

Note: The compounds are ingested by endocytosis by a vacuole and excreted by exocytosis. These compounds, isolated from the cytosol, are contained in the cells. Lysosomes are vesicles which ingest and digest food. This is endocytosis, although in various cells it differs.
