The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. Haploid describes a cell that contains a single set of chromosomes. In humans, only their egg and sperm cells are haploid. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). Haploid is the quality of a cell or organism having a single set of chromosomes. Specialized cells of the gametophyte undergo mitosis to produce sperm and egg cells (1n), which combine in fertilization to make a zygote (2n). Haploid (1n) spores germinate and undergo mitosis to produce a multicellular gametophyte (1n). What is the first cell type formed in the haploid generation?Įxample of alternation of generations: life cycle of a fern. Pollens produce male gametes which is a haploid (n) structure. It quickly undergoes meiosis to produce more haploid gametes that repeat the life cycle. ![]() When the haploid gametes fuse, they form a diploid zygote. Organisms with a haploid life cycle spend the majority of their lives as haploid gametes. The haploid life cycle is the simplest life cycle. Therefore, haploids contain only the chromosome set found after meiosis in male (sperm cells) or female (egg cells) gametes. What is a haploid plant? Haploid plants originate from gametes (or gamete-like cells) that do not go through fertilization, but can still generate a viable individual. The fluctuation between these diploid and haploid stages that occurs in plants is called the alternation of generations. The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes.
