Thus the correct answer is option (D). Secondary oocytes are haploid in nature. Note:The asexually reproducing organisms are haploid in nature. Sexually reproducing organisms are diploid as they contain two sets of chromosomes one from each parent.
Which of the following is haploid?
The primary oocyte undergoes the second meiotic division to form haploid secondary oocyte and a polar nuclei. The secondary oocyte undergoes maturation to form the ovum after being fertilized by the sperm. So, the correct answer is option C.
Is Oogonia haploid or diploid?
|Cell type||ploidy/chromosomes||Process completion|
|primary Oocyte||diploid/46||Dictyate in prophase I until ovulation|
|secondary Oocyte||haploid/23||Halted in metaphase II until fertilization|
|Ootid||haploid/23||Minutes after fertilization|
Are Oogonia haploid?
In many algae (e.g., Chara), the main plant is haploid; oogonia and antheridia form and produce haploid gametes. The only diploid part of the life cycle is the spore (fertilized egg cell), which undergoes meiosis to form haploid cells that develop into new plants.
Is the Nucellus haploid or diploid?
The ploidy level of the plant is diploid. Hence, the ploidy level of nucellus is 2n. MMC is a microspore mother cell, also known as meiocyte which undergoes meiotic division and produces female gametes.
Is a Spermatid haploid or diploid?
A spermatid is the final product of spermatogenesis. It is a haploid cell, meaning it has only one copy of each allele (one of each chromosome instead of two). Normal diploid cells have two copies of each chromosome, for a total of 46. Spermatids have half this number, for a total of 23 chromosomes.
What are 2 types of haploid cells?
They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
What are two examples of diploid cells?
Examples of diploid cells include blood cells, skin cells and muscle cells. These cells are known as somatic cells.
Which cells in humans are haploid?
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
Are Synergids haploid?
The synergid cells direct pollen tube growth to the female gametophyte. It makes possible the access of the tube into the embryo sac. Complete answer: … As these 8 nuclei are derived from the mitotic divisions of the haploid megaspore, these are haploid and thus, the synergids are haploid cells.
