검증된 단계별 안내1
Understand the concept of reproduction: Reproduction is the biological process by which organisms produce offspring. It can be classified into two main types: asexual reproduction (involving a single parent and no gametes) and sexual reproduction (involving two parents and the fusion of gametes).
Learn about paramecium reproduction: Paramecium primarily reproduces asexually through binary fission, where the organism divides into two genetically identical daughter cells. However, it can also undergo conjugation, a form of sexual reproduction, to exchange genetic material under certain conditions.
Learn about sea urchin reproduction: Sea urchins reproduce sexually. They release eggs and sperm into the water, where external fertilization occurs, leading to the formation of a zygote that develops into a larva and eventually into an adult sea urchin.
Compare the reproduction methods: Paramecium predominantly uses asexual reproduction, while sea urchins rely on sexual reproduction. This distinction is based on their biological processes and reproductive strategies.
Select the correct answer: Based on the information provided, the correct answer is 'Paramecium uses asexual reproduction; sea urchin uses sexual reproduction.'
