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.
What is the function of the style in the flower?
The style in a flower is part of the female reproductive structure that connects the ovary to the stigma, allowing pollen to reach the ovules for fertilization. It plays a crucial role in the pollination process by providing a pathway for pollen tubes to grow and facilitate fertilization.
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.
Ways pollen can move?
There are three common kinds of pollination: self pollination, wind pollination, and insect pollination. •Self pollination is when the pollen in the stamen (male part of the plant) drops into an ovule (egg) in the ovary of the stigma (female part) of the same plant. This is why it is called self pollination. • Wind pollination occurs in plants that are all-male (its flowers only containing stamen) and all-female (its flowers only containing the stigma). The stamen develops millions of pollen grains in the spring, as the chance of the pollen reaching an all-female plant is very little, and releases it in the summer. The few pollen grains that reach an all-female plant will be likely to reach an ovule in the stigma and pollinate the ovule. • Insect pollination is used by a lot of plants. This method of reproduction is when an insect such as a bee, butterfly, moth, or sometimes a bat, reaches a flower and sucks out the nectar in the flower. As they do this, the pollen gets stuck in their legs, and when they suck the nectar from the flower of another plant, the pollen gets onto the flower and into the stigma. If the pollen from a different type of plant is put into a stigma of a plant, pollination won't occur, so God has designed the bees of each hive to suck nectar from one kind of flower each day, so that the chance of pollination will be more.
Does the anther hold pollen?
Yes because pollen grains form on the tip of the anther.
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.
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.
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.
What is the functions of stigma?
The stigma of a flower is the receptive surface for pollen deposition, facilitating fertilization. It plays a crucial role in sexual reproduction by capturing pollen grains that can then germinate and grow pollen tubes to reach the ovules for fertilization.
How does a pollen tube form?
A pollen tube forms when a pollen grain lands on the stigma of a flower and germinates. The pollen grain absorbs water and begins to grow a tube that will penetrate the style of the flower and reach the ovary. This is a crucial step in the process of fertilization in plants.
Why will the fruit develop after removing the stigma of a flower?
Once the stigma is removed from a flower, it is no longer able to receive pollen for fertilization. Without fertilization, the ovary of the flower will not develop into a fruit. Pollen must be able to reach the stigma for fertilization to occur and for fruit development to take place.
What is the function of the style in the flower?
The style in a flower is part of the female reproductive structure that connects the ovary to the stigma, allowing pollen to reach the ovules for fertilization. It plays a crucial role in the pollination process by providing a pathway for pollen tubes to grow and facilitate fertilization.
What happen during process of pollination?
During pollination, pollen grains are transferred from the anther of a flower to the stigma of the same or another flower. This can occur through various agents such as wind, water, insects, birds, or other animals. Once on the stigma, the pollen grain germinates, producing a pollen tube that grows down the style to reach the ovary and fertilize the ovules.
How does the pollen reach the stigma?
some pollen grains reach to stigma by wind and some are carried by animals like rabbits and insects like butterfly, bee etc.
What part of the flower does pollen travel through?
Pollen travels through the style, which is the elongated part of the pistil located between the stigma and the ovary. When pollen lands on the stigma, it germinates and forms a pollen tube that grows through the style to reach the ovary, where fertilization occurs. This process is essential for the reproduction of flowering plants.
What is the long extension of the ovary called of the flower?
The long extension of the ovary in a flower is called the "style." The style connects the ovary, which contains the ovules, to the stigma, where pollen is received. It plays a crucial role in the fertilization process by allowing pollen tubes to grow from the stigma down through the style to reach the ovary.
What takes place when pollen lands on the stigma?
When pollen lands on the stigma of a flower, it germinates and grows a pollen tube through the style to reach the ovary. This process allows for fertilization to occur, where the sperm travels down the pollen tube to fertilize the egg cell in the ovule. This ultimately leads to the formation of seeds within the ovary.
