What happens once the pollen lands on the stigma?
Pollination
What is the process of pollination?
Pollination is the transfer of pollen from the male part of a plant (anther) to the female part (stigma), enabling fertilization and seed production to occur. This can happen through various mechanisms, such as wind, water, insects, birds, or animals carrying the pollen between plants. Once the pollen reaches the stigma, it travels down the style to fertilize the ovules in the ovary, ultimately leading to seed formation.
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 happens to the identity of the atom when an electron leaves the nucleus?
Electrons are not part of the atomic nucleus.
What is the difference between pollination and fertilization in angiosperm?
Pollination is the transfer of pollen from the anther to the stigma, while fertilization is the fusion of the male gamete with the female gamete to form a zygote. In angiosperms, pollination leads to the transfer of pollen to the stigma, followed by fertilization of the egg cell within the ovule to produce a seed.
What structure are you likely able to see in the pollen tube and when would you be able to see it?
You are likely to see the tube cell, vegetative nucleus, generative cell, and the tube nucleus in a pollen tube. This structure can be observed during the process of pollination when the male gametophyte is being transported from the pollen grain to the ovule.
What is it called when a pollen nucleus joins with the ovule nucleus?
Pollination
Which happens first pollination or fertilation?
Pollination. Fertilization is what occurs after pollination.
What doese pollination mean?
Pollination happens is when the pollen goes into the ovary.
What happens during the processes of cross-pollination and self-pollination?
there is not to big of a differents
What happens after pollinating flowers?
the pollination grow into
What process happens when pollen falls on a flowers pistil?
When pollen falls on a flower's pistil, a process called pollination occurs. The pollen travels down the pistil to reach the ovary, where fertilization takes place. This fertilization leads to the formation of seeds, which eventually develop into fruits.

When does pollination happens?
Cross pollination happens when the pollen of one flower is placed upon the stigma of another flower, whether of the same varietyor not.
