Its a fact of life, organisms cannot spontaneously appear! That has already been disproven! Organisms must come from other like organsms. Some dont need a partner, other do. we call the act of making or having offspring, REPRODUCTION.
Protist- Protist are able to reproduce asexually using Mitosis.
Annelids- Annelids can reproduce sexually, or asexually, it just depends on what kind of worm you have. In asexual reproduction they break of a section of their own body that will grow into another annelid. During sexual reproduction, they reproduce similar to how we humans do.
Insects-Very similar to other animals, it requires both a male and a female, and direct contact. The female insect will hold the eggs in her body and lay them once the male insect has fertilized her.
Amphibians-reproduce sexually. A female amphibian lays her eggs with a gelatinous coating over them in water then a male deposits clouds of sperm over them.
Mammals- Are fertilized in the female when they both reach sexually maturity, the male fertilized the female and the baby is born from the woman, not in an egg.
Nonvascualar Plants- can produce sexually or asexually. In asexual reproduction, a piece breaks off and falls into the ground, This piece them takes root and grows into a plant. In sexual reproduction, They may get help from a bee or some sort and carry the gametes from flower to flower.
Gymnosperm-Since these plants do not have flowers, they produce male and female parts that are fertilized when the male gamete (pollen) has contact with the ovule.
Angiosperms- Angiosperms have flowers that Allow outside help to come and pollinate them. Humming birds, bees, and other pollen eating, nectar attracted animals aid in helping out with reproduction in this area.
