Asexual reproduction
Sea stars are capable of both types of reproduction.
Protists can reproduce both asexually and sexually, depending on the species and environmental conditions. Asexual reproduction methods commonly include binary fission, budding, and spore formation. However, some protists also engage in sexual reproduction, particularly when facing stress or unfavorable conditions, to increase genetic diversity. Thus, while many protists are capable of asexual reproduction, they are not exclusively asexual reproducers.
I believe you are thinking of sexual reproduction. The opposite of sexual reproduction is asexual reproduction which occurs when offspring are produced without a male. Asexual reproduction is common among certain plants and single-celled organisms like bacteria and protists. Some species of animal can switch back and forth between sexual and asexual reproduction. Turkeys are a good example of this. Female turkeys can produce fertilized eggs in the absence of a male. Aphids are also capable of producing young in the absence of a male.
The longest part of the life cycle is typically the adult stage. This is when the organism is fully developed and capable of reproduction, and it can last for a significant amount of time depending on the species.

Sea stars are capable of both types of reproduction.
Starfish are capable of asexual reproduction through a process called fission, where a new individual is formed from a part of the original organism.
Fragmentation is a form of asexual reproduction in which an organism breaks into fragments, with each fragment capable of growing into a new individual. This process is common in organisms like plants, fungi, and some invertebrates. Sexual reproduction involves the fusion of gametes from two parents to produce genetically diverse offspring.
Organisms that are capable of regeneration or asexual reproduction can benefit by quickly replacing lost or damaged body parts without needing a mate for reproduction. This can increase survival rates in challenging environments or situations where finding a mate is difficult. Additionally, asexual reproduction can lead to rapid population growth in favorable conditions.
No, not all plants undergo sexual reproduction. Some plants are capable of asexual reproduction through processes like vegetative propagation or fragmentation.
Bacteria, archaea, and some protists are capable of reproduction through asexual mitosis. Mitosis is a form of cell division where a single cell divides to produce two identical daughter cells. This process allows these organisms to reproduce and multiply rapidly.

A starfish can reproduce by mating with another starfish or asexually. Asexual reproduction is usually done after a starfish experiences dismemberment. The dismembered arm can grow into a whole new starfish.
