Question

Modes of reproduction used by single organism?

Answer 1

asexual
reproduction, and vegetative propagation.

Answer 2

❣️Bacteria and Binary Fission❣️

Many single-celled organisms rely on binary fission to reproduce themselves. All bacteria reproduce by binary fission.

❣️Fragmentation and Blackworms❣️

Many species of annelids (worms) reproduce via an asexual process called fragmentation. Included in this category of worms are California blackworms, or mudworms. These worms are hermaphroditic -- they have both male and female reproductive parts -- and can reproduce sexually. However, many times these worms will reproduce using fragmentation. In this case, blackworms can break apart and each consequential fragment can become a new worm.

✴️Budding and Hydras✴️

Hydras are a type of freshwater cnidarian related to jellyfish, sea anemones and corals. Hydras reproduce asexually by developing small, genetically identical polyps that protrude from the parent. These polyps break off from the parent to form a new organism in a process called "budding."

⭐Parthenogenesis and Copperheads⭐

Though most of the organisms that use asexual reproduction are invertebrates, several species of vertebrate animals do make use of it. Some, like copperhead snakes, can reproduce asexually as an alternative to their typical sexual reproduction. Through a process called parthenogenesis -- literally "virgin birth" -- copperhead females can give birth to live young without having been inseminated by a male, even when males are available, according to National Geographic. In this form of parthenogenesis, the polar body, or a cell produced alongside the female's egg, acts as a sperm cell and essentially "fertilizes" the egg. Parthenogenesis has been observed in several species of reptiles, birds and sharks, and is especially common in insects.

Vegetative Propagation and Strawberries

Many plants reproduce asexually through vegetative propagation, which can either be naturally occurring or produced artificially. In vegetative propagation, plant tissues and organs are regenerated from another part of the plant, and a new organism can be produced. Strawberries naturally reproduce via this method. The horizontal stems -- called runners or stolens -- of strawberries grow from parent plants, and tiny plantlets form along these runners, forming roots along the way. When there is a break in the connection to the parent plant, the plantlets become new independent organisms.
