What are the types of life cycles?
A life cycle is a period involving one generation of an organism through means of reproduction, whether through asexual reproduction or sexual reproduction. In regard to its ploidy, there are three types of cycles; haplontic life cycle, diplontic life cycle, diplobiontic life cycle.
What type of life cycle do humans and other vertebrates have?
Vertebrates typically have three stages to their life cycle: egg, baby or juvenile, and adult, although a few, like some amphibians, undergo a metamorphosis stage prior to becoming an adult.
Do humans have a diplontic life cycle?
Humans have a diplontic life cycle because the multicellular stage is diploid. The zygote grows by mitosis into a diploid, multicellular organism. Part of this multicellular organism undergoes meiosis to produce haploid cells called gametes within structures called gametangia (gametangium, singular).
How are the two life cycles different between humans and plants?
The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ”2n”). Plants, however, can live when they are at the stage of having haploid cells or diploid cells.
Do sponges have a Gametic life cycle?
Most sponges are hermaphrodites, but an individual will usually only make one type of gamete at a time, so they are not able to self-fertilize. The sponge life cycle includes sexual reproduction. Sponges may also reproduce asexually.
What is the dog life cycle?

Where does the embryo develop in the human life cycle?
The following is the different stages of development in the human life cycle The sperm from the adult male human and the egg from the adult female human form a zygote inside the uterus of the female. Over time, the zygote develops and forms into an embryo.
