Detailed explanation-1: -An organism possessing both male and female organs is called hermaphrodite. Males in sexually reproducing species have organs that create male gametes, often called sperm. Female gametes, referred to as eggs, are produced by various sexual organs in females.
Detailed explanation-2: -A hermaphrodite is an organism (plant or animal) having both male and female reproductive organs.
Detailed explanation-3: -Hermaphroditism is usually identified by gonad morphology; there are three main groups or categories. One is synchronous hermaphrodites, in which mature testicular and ovarian tissues are present at the same time, and both produce sperm and ova, respectively.
Detailed explanation-4: -This may sound confusing, but some organisms are hermaphroditic, meaning they contain both male and female gametes. In this instance, those organisms are able to self-fertilize. Despite the fact that these gametes come from the same individual, we still consider this sexual reproduction, as two gametes are involved.
Detailed explanation-5: -Examples-tunicates, few snails, earthworms etc, are hermaphrodites.
