How does the nucleus in a pollen grain get from the stigma to the ovary of a flower?
they germinate and grow a small tube all the way to the ovary
Which part of the plant does the pollen grain need to land?
The pollen grain needs to land on the stigma of the plant for successful pollination to occur.
How close to the egg can the pollen grain get?
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.
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.
Where does germination of the pollen grain occur in flowering plants?
Germination of the pollen grain typically occurs on the stigma of the carpel (female reproductive organ) in flowering plants. The pollen grain produces a pollen tube through which the male gametes travel to fertilize the ovule.
How do the sperms nuclei in a pollen grain reach the egg nucleus in an ovule?
When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.
Why do the stigma is sticky?
The stigma catches pollen and the pollen grain germinate on the stigma. The stigma is sticky to catch and trap pollen with various hairs or flaps.

How does fertilization take place in flowers?
the pollen grain lands ot the tip of pistle called as stigma and then pollen tube from pollen grain germinates and it reaches the ovary through style(containing 2 male gamets).. then fertilisation takes place... or is when the male sex cells inside the pollen grains fuses with the female sex cells inside to produce a seed embryo Pollination transfers the pollen grain to the stigma. However, for hertilisation to take place, the nucleus of the pollen grain must fuse with the nucleus of the ovum, which is inside an ovule in the ovary. To transfer the nucleus to the ovum, the pollen grain grows a tube, which digest its way through the tissue of the style and into the ovary. Here it grows around the opening in an ovule. The tip of the tube dissolves and allows the pollen grain nucleus to move out of the tube and into the ovule. Here it fertilises the ovum (egg cell) nucleus.

What is the part of the flower that receives the pollen grain from the anther?
The stigma is the part of the flower that receives the pollen grain from the anther. It is the receptive surface where pollination occurs in the reproductive process of flowering plants.
Where does germination of the pollen grain occur in flowering plants?
Germination of the pollen grain typically occurs on the stigma of the carpel (female reproductive organ) in flowering plants. The pollen grain produces a pollen tube through which the male gametes travel to fertilize the ovule.
When a flower is pollinated the grain of pollen falls were?
When a flower is pollinated, the pollen grain lands on the stigma of the flower, which is the female reproductive organ. The pollen grain then germinates, forming a pollen tube that grows down through the style to reach the ovary where fertilization can occur.
What is transferring pollen grains from another to the stigma of a flower?
when pollen grain are transferred from the stigma the ovule of the flower , whats takes place
