Reproduction is the process of producing offspring. There are two types of reproduction-
sexual reproduction and asexual reproduction. Most of the higher plants and animals undergo sexual reproduction, which involves the fusion of gametes. Asexual reproduction involves spore formation generally. Vegetative reproduction is a type of asexual reproduction that is seen in plants.. Budding,fission are few of the types of asexual reproduction seen in lower animals. Thus metabolism, sexual and asexual reproduction are common attributes for both plants and animals.
