In flowering plants, the pollen tube carries two male gametes through the maternal reproductive tissues to the embryo sac, which contains two female gametes.
How many male gametes can 4 produce?
The process of meiosis cell division helps in the production of the spores of the plants and the gametes. This will result in the four haploid gametes. In the process, there are pollen grains produced with two male gametes. Therefore, in total it produces four gametes.
Which part of the embryo sac receive the male gamete?
Secondary nucleus of embryo sac fuses with a male gametic nucleus and results triple fusion. B. Synergid directs the pollen tube growth and receive male gametes during fertilization.
How many male gametes and female gametes are produced by?
Gametes carry half the genetic information of an individual, one ploidy of each type, and are created through meiosis, in which a germ cell undergoes two fissions, resulting in the production of four gametes. In biology, the type of gamete one produces determines the classification of their sex.
What is the female sperm called?
Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.
Where is the male gamete made?
In flowering plants, male and female gametes are produced in the anther and ovule, respectively. Male gametes are contained within pollen grains, which are released from the anthers at anthesis.
How many gametes does pollen Tetrad?
Answer: One pollen mother cell gives rise to a pollen tetrad(4 pollen grains ) by meiosis. In one pollen grain , for angiosperms(flowering plants), 2 male gametes are produced for double fertilization.
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.
