What is the part of the flower that receives the pollen grain from the anther?
The stigma recieves the pollen grain from the anther. It then travels down the pollen tube inside the style and goes to the ovary.
What serves as a bridge between the pollen grain and the egg?
The pollen tube serves as a bridge between the pollen grain and the egg in flowering plants. Once the pollen grain lands on the stigma, it germinates and forms a pollen tube that grows down through the style towards the ovary, where it delivers the male gametes to the egg for fertilization.
What is the role of stigma in plant reproduction?
Stigma is the receptive surface of the female reproductive organ in a flower where pollen is deposited. Its role is to capture and stimulate the growth of pollen tubes for fertilization to occur, facilitating successful reproduction in plants. Stigma morphology and behavior can influence pollen transfer and compatibility, impacting the reproductive success of a plant species.
How do the sperm 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.
How does pollen that fertilizes the egg reach the ovule?
Some of the pollen grains carried by wind,insects,birds or bats may reach a carpel and stick to the ripe stigma.Each pollen grain produces a tiny tube which grows down to the style,into the ovary and towards the ovules or egg cells.when one of the tubes reaches an ovule,it bursts open.A male nucleus from the pollen grain then moves down the pollen tube to join with the nucleus of the female sex cell,the ovule.when the nuclei of the pollen grains and ovules have joined together, the ovules are said to be fertilized.
When a flower is pollinated a grain of pollen falls on a what?
When a flower is pollinated, a grain of pollen falls on the stigma, which is the tip of the female reproductive structure called the pistil.
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 happens to a pollen grains on the stigma?
pollen grain develop a tube that goes down the style
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.
When a pollen grain reaches the stigma of another flower of a plant of the same species what happens next is called?
When a pollen grain reaches the stigma of another flower of the same species, the process that follows is called pollination. The pollen grain germinates on the stigma, forming a pollen tube that extends down the style toward the ovary. This tube transports sperm cells to the ovule, leading to fertilization and the formation of seeds.
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.
What is the part of the flower that receives the pollen grain from the anther?
The stigma recieves the pollen grain from the anther. It then travels down the pollen tube inside the style and goes to the 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.
What happens if more than one pollen grain is deposited on the stigma at the same time?
the fastest one gets to fertilize
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
