A life cycle where generations alternate between haploid (n) and diploid (2n)
Alternation of generation
A life cycle where generations alternate between haploid n and diploid 2n. Alternation of generation. In this process, the life cycle of an organism alternates between a haploid phase, which has one set of chromosomes, and a diploid phase, which has two sets of chromosomes.

A plant hormone that stimulates cell division to grow roots, fruits, and branches
Cytokinin
A plant hormone that stimulates cell division to grow roots, fruits, and branches. Cytokinin. Cytokinin is a substance in plants that helps cells divide and grow, influencing the development of roots, fruits, and branches.

Fertilization in angiosperms, which produces a diploid zygote and triploid endosperm
Double fertilization
Fertilization in angiosperms, which produces a diploid zygote and triploid endosperm, double fertilization. Double fertilization is when one sperm cell fertilizes the egg to form a zygote and the other combines with two nuclei to form the nutrient-rich endosperm.

A change in a plant’s growth in response to external factors, like growing towards the light
Tropism
A change in a plants growth in response to external factors, like growing towards the light. Tropism. Tropism is the way plants grow or move in response to environmental signals, such as light or gravity.
