What is the role of the zygote in organisms that have a haploid-diplontic life cycle?
Understand the Problem
The text discusses the formation and development of the zygote in various organisms, particularly focusing on its role in sexual reproduction and the various life cycles it undergoes, such as haploid and diploid cycles.
Answer
The zygote forms a multicellular diploid organism via mitosis.
In organisms with a diplontic life cycle, the zygote undergoes repeated mitotic divisions to develop into a multicellular diploid organism. This organism later produces haploid gametes through meiosis.
Answer for screen readers
In organisms with a diplontic life cycle, the zygote undergoes repeated mitotic divisions to develop into a multicellular diploid organism. This organism later produces haploid gametes through meiosis.
More Information
In a diplontic life cycle, such as in humans, the diploid phase is dominant and multicellular. The zygote represents the starting point for the development of the entire organism.
