In a grain of pollen,what is the function of the sperm cell that doesn't join with the egg cell?
Hey, why don't you go look on your science book or listen to the teacher instead of looking in the internet .....
There are two things that must join to make a seed. The zygote, or embryo, must join with the ovule.
pollen
The answer is no. The anther contains pollen which contains sperm cells. Mainly through pollination, the pollen from the anther travels down the pistil, and meets the egg where it fertilizes the egg.
The male reproductive tract carries sperm. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, vas deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra.
During pollination, the sperm of the male gametophyte are not flagellated because they generally do not move. They rely on the growth of a pollen tube to deliver them to the egg cell.
this is because premature pollen grain do not contain the sperm cell for fertilization. only the generative nucleus in mature pollen grain will divide mitosisly to form sperm cell for fertilization
pollen
no the pollen grain contains the male genetic material - sperm cells
whats the answer to the tube that grows out of a pollen grain contains a what
pistil Sperm is formed in the pollen tube while travelling through the style of the pistil.
when a pollen grain lands on the stigma it creates a pollen tube that goes down to the egg where sperm fuzes with the egg.
pollen tube
Within a single pollen grain there are 2 sperm cells
plant sperm
its like the sperm of plants
i do think it does in humans but it might in plants.
the sperm nucleus is found in pollen grains and directs the growth of the pollen tube to the ovule in the ovary, it then degenerates
