What kind of asexual reproduction does a earthworm use?

Answer 1

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.

Answer 2

Earthworms each have male and female reproductive organs. To produce offspring, two earthworms must join at the male end of one worm and female end of the other. After they have exchanged spermatophores, a cocoon is formed and after about three to five weeks, they hatch.

Answer 3

Earthworms reproduce asexually through a process called fragmentation. In this process, a portion of the worm's body can break off and regenerate into a new individual with the same genetic information as the parent.

Answer 4

They don't; earthworms use sexual reproduction, but as they're hermaphrodites, both partners get one another 'pregnant' and then combine their eggs in a single capsule. Cute, isn't it? ^^

Answer 5

It shows transverse binary fission .
