Comparing The Kingdoms Plantae And Animalia

250 Words1 Page
Members of the kingdoms Plantae and Animalia have long since diverged evolutionarily, but still share certain biological traits. In cell biology, both kingdoms have nuclei, which house chromosomes that store genetic information. Ribosomes and mitochondria are also present. Organelles not in plant cells are golgi apparatuses and lysosomes of the endomembrane system. Centrioles (absent in most plants) aid cell division in animals. Animal cells lack cell walls, plastids, and vacuoles. Developmentally, certain diploid cells of sporophytes in the Kingdom Plantae undergo sporic meiosis, followed by mitosis. As gametophytes, plants combine genetic information through fertilization, creating a zygote. By mitosis, the zygote develops into a sporophyte.
