How do you xxplain the structure of the pollen grain describe the development of pollen grain and male gamete?
While still attached to the anther, the nucleus of the pollen grain divides, producing two nuclei, one of which becomes the tube nucleus, the other is called the generative nucleus. The generative nucleus divides again, forming two sperm cells.
Once the pollen grain is released from the anther, it is transported (by wind or fauna) to the stigma of the female flower. Once a pollen grain has landed on the stigma, it begins to grow a pollen tube (there are three nuclei in the pollen tube, one from the tube nucleus, and the two sperm). When the pollen tube reaches the ovary, both sperm cells enter the ovule, one fuses with the egg nucleus, the other fuses with polar nuclei that is also inside the ovule, forming the endosperm.
What else can I help you with?
What structure have they evolved to obtain gamete exchange?
Pollen
What is the best way to describe a gamete?
a haploid cell
Which stage of development involves initial cellular reorganization?
gamete formation
What functions of female gamete?
The primary functions of the female gamete (egg or ovum) are fertilization by a male gamete (sperm) to create a new organism, containing half of the genetic material needed for reproduction, and supporting the development of the new embryo into a fetus within the uterus.
Where in the flowering plant does the male gamete form?
The male gamete in flowering plants forms in the anther, which is part of the male reproductive structure known as the stamen. Within the anther, pollen grains containing the male gametes develop.
What structure have they evolved to obtain gamete exchange?
Pollen
What is another word to describe a gamete?
A sperm or egg cell.

What name do you use to describe a cell with only one of each chromosome?
A Gamete.
What structure have seed plants evolved to obtain gamete exchange?

Is embryo a gamete?
No, an embryo is not a gamete. A gamete is a specialized reproductive cell (sperm or egg) that fuses with another gamete during fertilization to form a zygote, which then develops into an embryo. An embryo is the early stage of development after fertilization.
What functions of female gamete?
The primary functions of the female gamete (egg or ovum) are fertilization by a male gamete (sperm) to create a new organism, containing half of the genetic material needed for reproduction, and supporting the development of the new embryo into a fetus within the uterus.
Differences between gamete and a gametophyte?
A gamete is a mature reproductive cell (sperm or egg) that fuses with another gamete during fertilization. A gametophyte is a haploid multicellular plant structure that produces gametes through mitosis. Gametes are reproductive cells in animals, while gametophytes are multicellular structures in plants that produce gametes.
What is the Result of a male gamete fertilizing a female gamete?
The result of a male gamete fertilizing a female gamete is a zygote.
How would you describe the process of miosis?
There is two cycles to the process of meiosis. The cycles are involving a gamete mother cell and dividing them into fourths.
Where in the flowering plant does the male gamete form?
The male gamete in flowering plants forms in the anther, which is part of the male reproductive structure known as the stamen. Within the anther, pollen grains containing the male gametes develop.
