some pollen grains reach to stigma by wind and some are carried by animals like rabbits and insects like butterfly, bee etc.
What else can I help you with?
Can the flower bears food if the stigma is cut off?
No, because pollen cannot reach the ovary. Stigma is necessary for trapping pollen and for rehydration of pollen tube to grow. So no fertilization occurs.
Where in the flower do pollen grains land in order to begin the process of fertilization?
Pollen grains land on the stigma of the flower, which is the sticky structure at the top of the pistil. Once the pollen grains land on the stigma, they can germinate and grow a pollen tube through the style to reach the ovules in the ovary for fertilization to occur.
Where does pollen enter the female part of a plant?
Pollen enters the female part of a plant through the stigma, which is the sticky, receptive surface located at the top of the pistil. From the stigma, the pollen travels down the style to reach the ovary, where fertilization takes place.
What receives the pollen during fertilization?
During fertilization in flowering plants, the stigma of the pistil receives the pollen. The stigma is the sticky top part of the pistil, which captures and holds the pollen grains. Once the pollen lands on the stigma, it germinates and forms a pollen tube that travels down the style to reach the ovary, where fertilization occurs.
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.
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.
What is the union of the pollen and the stigma?
Pollination is the union of the pollen and the stigma.
What The part of the pistil that receives pollen?
Pollen is collected in the stigma.
How does the pollen not Reach the stigma of another flower?
Pollen is transferred by wind, insects, or animals ensuring it does not reach the stigma of another flower. Different plant species have mechanisms in place to prevent self-fertilization and promote genetic diversity. These methods include temporal separation of male and female reproductive organs, physical barriers, and chemical barriers to prevent pollen from reaching the stigma of another flower.
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.
How does pollen make it from the stigma down to the ovary?
It makes a seed Edited answer: In nature, pollen does not get into ovary, rather it land on the stigma and their it allowed to germinate to send pollen tube to the ovary only if it is compatible. Otherwise it is rejected by the stigmatic cells and withers away.
What part of the plant receive pollen?
stigma
