WebThis type of life cycle is called a haplodiplontic life cycle (Figure 20.1). It differs from our own diplontic life cycle, in which only the gametes are in the haploid state. In haplodiplontic life cycles, gametes are not the direct … WebFern is a diploid plant body. Meiosis leads to formation of cells that contain half the number of chromosome than parental cells. In ferns, these cells are the spores. So a spore is the …

WebFigure 11.11 Plants have a life cycle that alternates between a multicellular haploid organism and a multicellular diploid organism. In some plants, such as ferns, both the …
WebA zygotic meiosis is a meiosis of a diploid zygote immediately after karyogamy, the fusion of two cell nuclei.In this way, the organism ends its diploid phase and produces several haploid cells. These cells undergo mitosis (divide mitotically) to form either larger, multicellular individuals, or more haploid cells. Two opposite types of gametes (e.g., male …

The haploid spores bear mitosis to form haploid gametophytes. The haploid gametes are shaped by the meiosis of the sporophyte. This is a diplontic life cycle. Hence, Zygotic meiosis occurs in Algae. daycoval fgtsWebFor homosporous land plants (i.e., bryophytes, many ferns and lycophytes), their sexual reproduction will now be described using a three-sex model which arises from the previously described acceptance of both meiosis and fertilization being sexually reproductive processes within the land plant life cycle. daycoval webWebExample of a diploid-dominant life cycle: the human life cycle.
