What happens when pollen is moved from the anthers to the stigma?
Pollen grains contain the male gamete (sex cell).
How does fertilization in plants?
the pollen grains after landing on the stigma germinate to send out pollen tubes through which the male gametes reach near the egg cell of embryo sac in the ovule to fuse with. this fusion of male and female gametes (egg cell) is called fertilization.
What is the structure that develops into a pollen grain?
First pollen falls from a male cone onto a female cone. In time a sperm cell and an egg cell join together in an ovule on the female cone
What grows down from the pollen grain after pollination?
A pollen tube emerges out from the pollen grain fallen on the stigma which leads the male sex cell to the ovary through style (a connection stigma & ovary.
How pollen grains reach pistil?
Pollen grains reach the pistil through pollination. The pollen grains are placed on the stigma of the carpal, and it transfers by wind, insects, built in mechanical discharge, and men. When the pollen lands on the stigma, it starts a series of chemical reactions that allow the pollen grain to produce a structure called the pollen tube. At the same time, the generative nucleus divides and produces two sperm nuclei. The pollen grain with the pollen tube and three nuclei is a mature gametophyte. The pollen tube works its way through the style of the carpal and touches the micropyte of the ovule. The sperm nuclei enter the embryo sac and fertilizes the egg and two polar nuclei, referred to as double fertilization. The fertilized egg develops into the immature seed plant, and the central cell develops into the endosperm, or food storage ares, of the seed.

What are grains that produce sperm cells called?
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
Where are a plants sperm cells located before fertilization occurs?
When a pollen grain is immature male gametophyte, it has two cells ,a generative cell and a tube cell. A pollen grain becomes a mature male gametophyte when the generative cell divides by mitosis to form two sperm cells. In most species, this process occures after the pollen grain lands on the stigma of a carpel and the pollen tube begins to form. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

How would plants reproduce?
Flowering plants reproduce by transferring pollen from a male organ (anthers) to a female organ (stigma)), the pollen grains germinate and send out the pollen tubes in the ovules. There the nucleus of the male cell joins with that of a female cell, and ovary starts growing in the form of a fruit. The ovules get convertd in to seeds. On maturity these seeds are dispersed and germinate to form new plants.
How do pollen grains reach the pistil?
The pollen grain reach the pistil either by self-pollination or by cross pollination by pollinators.
Name two ways that plants ensure that their pollen grains have a greater chance of reaching the female part of their flowers?
they produce a tiny tube that the pollen grains travel to the egg cell.
