The dominant phase in a haploid dominant life cycle is the haploid phase.

The only haploid part of the organism's life cycle in a diploid dominant life cycle is the gametes.

In haploid dominant life cycles, the zygote undergoes meiosis, while in diploid dominant life cycles, the zygote undergoes mitosis.

The Excavata group of unicellular eukaryotes lacks mitochondria and reproduces asexually.

Diplomonads possess two nuclei and lack typical mitochondria.

Parabasalids move using flagella and by undulating their membrane.

A mixotroph is an organism that is both photosynthetic and heterotrophic.

Primary endosymbiosis in Archaeplastida led to the engulfment of cyanobacterium, giving rise to green algae and land plants.

Rhizomes are underground stems that form new individuals, while stolons are above-ground stems that also produce new individuals.

Apomixis is the formation of seeds without fertilization, resulting in genetically identical offspring.

The calyx is the entire group of sepals and the cup-like structure they connect to, providing protection for the flower bud.

The corolla is the entire group of petals in a flower, usually serving to attract pollinators.

Vegetative propagation is a form of asexual reproduction involving human intervention, such as making cuttings to grow new plants.
