A single diploid cell yields four haploid sperm cells through meiosis. In a fertilised embryo sac, the only haploid structures that are present are the antipodal cells, if fertilization does not occur through the chalazal end,diploid structure is zygote,and triploid structures is primary endosperm nucleus. (b) Anther- It is the part of the stamen where pollens are produced. While the details may vary between species, the overall development of the female gametophyte has two distinct phases.

This process is required to produce egg and sperm cells for sexual reproduction. Ploidy level measurements by flow cytometry revealed that 288 ovule-derived regenerants were haploid . Female gametophyte development begins early in ovule development with the formation of a diploid megaspore mother cell that undergoes meiosis. On the other hand, a haploid cell only has 23 chromosomes in it. Hint: All the parts of a flowering plant are diploid, That is stem, roots, leaves, branches etc. Is ovule diploid or haploid? The cells of a sporophyte body have a full complement of chromosomes (i.e., the cells are diploid, or 2n); the sporophyte is the typical plant body that we see when we look at an angiosperm. The precise defect in meiosis from which diploid embryo sacs arise in . a. Archegonium b. The chromosome in the haploid has a single set. The female cones (female strobili, singular strobilus) consist of megasporophylls that carry uncovered (Gymno = naked / exposed, hence Gymnosperms) ovules. After fertilization, an embryo sporophyte forms within the ovule; haploid tissue of the gametophyte and diploid tissue of the ovule integument form a tough capsule called a seed. Complete answer: Option A: Archesporial cells only function at the megaspore of the mother cell in the tenuinucellate ovules. The female and male inflorescence of the pine tree develop as cones on the sporophyte. Plants also have a diploid phase which is called the sporophyte. First, in the process of megasporogenesis, a single cell in the diploid megasporangium—an area of tissue in the ovules—undergoes meiosis to produce four megaspores, only one of which survives.During the second phase, megagametogenesis, the surviving haploid megaspore .
