Key Difference – Haplontic vs Diplontic Life Cycles In the context of biology, a biological life cycle is a sequence of changes a particular organism undergoes through means of reproduction (sexual or asexual) which finally returns to the original starting phase. As adjectives the difference between haplontic and diplontic is that haplontic is (biology) describing an organism that is haploid for most of its life cycle but that briefly has a diploid zygote while diplontic is of or pertaining to a diplont. The haplontic life cycle is exhibited by most members of Chlorophyta where the main plant body IS haploid and reproduces by vegetative multiplication or formation of mitospores (spores formed as a result of mitosis).
