If the gametes were diploid the number of chromosomes would double in each fertilization. Chlamydomonas is an example of a protist that presents a haploid phase in most of its life cycle.
Solution for animals and plants both have diploid and haploid cells.
Animal life cycle diploid haploid. Haploid cells are part of our life cycle as well as the life cycle of. In the diploid dominant life cycle the multicellular diploid stage is the most obvious life stage as occurs with most animals including humans. The haploid stage is reduced to single cell gametes which fuse immediately to recreate the diploid phase.
Most animals also have diplontic life cycles. A life cycle is defined as the series of changes a living thing goes through from the beginning of its life until its death. Haploid cells in animals are found in gametes however there are other organisms where the haploid phase is present in much of its life cycle.
Fertilization between the gametes forms a diploid zygote. In some plants such as ferns both the haploid and diploid plant stages are free living. How does the animal life cycle differ from the alternation of generations exhibited by.
