Almost all animal cells contain lysosomes. Lysosomes are most abundant in white blood cells, liver cells, lung cells, kidney cells, etc. RBC, yeast and most plant cells do not contain lysosomes. Recently lysosomes have been discovered in plant cells. Lysosomes in plant cells are called Spherosome or Oleosome. Lysosomes are found in onion seeds, bhutra and tobacco cells. Lysosomes have been found in some thallophytes plants.
