Question
The life cycle type in organisms in which the adult organism exists in haploid form is called?
Correct Answer
Option D is the correct answer.
Detailed Explanation
A haplophase or haplontic life cycle is one where the dominant, multicellular stage is haploid. The zygote is the only diploid stage, which undergoes meiosis to produce haploid individuals. Some algae and fungi have this life cycle. Diplontic (diplophase) means the adult is diploid (like humans). Haplodiplontic means there are both haploid and diploid multicellular stages (like plants).
Hint
'Haplo-' means single set of chromosomes. Which cycle has the adult in this state?
