Answer: Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid. So 23.
When the lysosomes of a cell rapidly digest the cell itself, this process is known as autolysis. This self digestion process helps in the decomposition of the dead cells. The cell is dismantled by its own lysosomes, which digests the remains of the dead cell. It is an essential process in the life cycle of a cell. This self digestion of the cells is extremely important for the new cells to grow.
Hence, the correct answer is 'autolysis'.
