Jawaharlal Nehru was not unconscious of his indebtedness to Indian history and tradition as a determining factor in the formulation of his policy of non-alignment. What I have done is to give voice to that policy (non-alignment)âI have not originated it.
Lysosomes are found only in animal cells and are vesicles of digestive enzymes. It is a membrane-bounded sac that holds enzymes. It is the little stomach of the cell because it is the center of digestion. Its main function is to clean up the cell by digesting macromolecules and cleaning up broken down organelles.
In cell biology, an organelle is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive. Organelles are identified by microscopy, and can also be purified by cell fractionation. There are many types of organelles, particularly in eukaryotic cells.
