Planaria are hermaphrodites, possessing both testes and ovaries. Thus, they can reproduce asexually with their own gametes or sexually with another planarian. In asexual reproduction, the planarian detaches its tail end and each half regrows the lost parts by regeneration. However several problems can occur with this, so this does not happen very often. Instead, in sexual reproduction, each planarian transports its excretion to the other planarian, giving and receiving sperm. Eggs develop inside the body and are shed in capsules. Weeks later, the eggs hatch and grow into adults. Sexual reproduction is desirable because it enhances the survival of the species by increasing the level of genetic diversity.

What are the two ways of reproduction?
Sexual (when they use two of different genders) and Asexual (when they are born 'pregnant'.)
How many parents does an asexual reproduction organism have?
Asexual means "not sexual": These organisms do not use sexual reproduction, which requires two parents. An asexual organism therefore only has one parent. Asexual organisms are simple and single-celled (unicellular). When the cell divides, the organism had reproduced. This has an advantage: The organism doesn't need another of its own kind to pass its genetic material on. It also has a disadvantage: The genetics of asexual organisms are less diverse. Sexual reproduction allows organisms to be more adaptible than asexual reproduction, since more unique combinations of genes can result with sexual reproduction.
Which types of organisms use meiosis strictly for reproduction?
Any kind of animal that is asexual uses meiosis for reproduction. Examples of these are sea sponges, star fish, protozoa, and many more animals.
How many parents are there in asexual reproduction?
The parents have to have part of each other connect to make a child but asexual is when the parents are made together so they have a kid when they are grown.
How do you use reproduction in a sentence?
Reproduction in plants can be both asexual and sexual. Reproduction is used correctly in the previous sentence. It is used to describe a process.
Reproduction in animals?
The vast majority of animals practice some kind of sexual reproduction. There are a few minor life forms that use asexual reproduction.
Are offsrings of asexual reproduction identical to the parent?
Yes they are. Such as Frogs they use the same kind of DNA.
What type of reproduction do flowers use?
pollination.sexualSexual and Asexual Reproduction
What do flowers use to make reproduction?
pollination.sexualSexual and Asexual Reproduction
How many parents are there in asexual?
There are no "parents" as such, as asexual reproduction is reproduction without the use of sex organs. Asexual reproduction is usually found in amoeba, and other single celled organisms.
Do bacterium use asexual reproduction?
