Answer:
Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life.
Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
A lysosome is a small vesicle-like eukaryotic organelle. It contains hydrolytic enzymes that break down waste material and cellular debris. ... Lysosomes digest excess or worn-out organelles, food particles and engulfed viruses or bacteria. Thus, they are called as disposal system of the cell.
