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.
Plasma membrane is also a phospholipid bilayer which is essentially a biomembrane that can cover a cell or a cell organelle. For example, lysosome is a cell organelle which contains hydrolytic enzymes and it is bound by a single layer of plasma membrane. While, mitochondria, the powerhouse of the cell is bound by two layers of plasma membrane. Even the nucleus is membrane bound in eukaryotic cells. Hope that helps.
