dexar [7]

A lysosome is a membrane-bound sac found in cells that contains digestive enzymes which break down complex molecules or structure.

Lysosomes are single membrane organelles or vesicles  that  contain enzymes and are  specialized to breakdown complex food materials  such as sugars and proteins, into simpler substances.

Lysosomes are made in a process that begins in the endoplasmic reticulum and ends in the Golgi apparatus which puts the finishing touches to the lysosome before releasing it into the cytoplasm where it floats freely until engaged.

Mitosis can occur in both haploid and diploid cells, but meiosis cannot occur in haploid cells. Why not?.
allochka39001 [22]

Mitosis can occur in both haploid and diploid cells because it is equational division where the number of chromosomes remain the same after division. But meiosis cannot happen in haploid cells because it is reductional division and haploid cells do not have any extra copy of chromosomes to be halved.

Mitosis is the cell division where the number of chromosomes do not change after cell division. It usually happens in the somatic cells of the body. Cancer cells also undergo mitosis

Meiosis is the cell division where the number of chromosomes are halved after cell division. The process of meiosis occurs in two phases: meiosis I and meiosis II. The germ cells of the body undergo meiosis.
