What does a pollen grain landing near an ovule produce?
If a pollen grain lands near an ovule, it can lead to pollination, where the pollen grain forms a pollen tube that grows towards the ovule. Once the pollen tube reaches the ovule, fertilization can occur, resulting in the formation of a seed.
In ovule formation what happens when the pollen tube does not pass through the micropyle?
If the pollen tube does not pass through the micropyle during ovule formation, fertilization cannot occur because the sperm cells contained within the pollen tube will not reach the egg cell. This will prevent the fusion of gametes and subsequently the development of seeds.
In which part of a plant would meiosis occur?
mitosis occurs in pollen sacs contained in the anther of the stamen and also in the ovule of the carpel. Edited answer: Mitosis takes place at all growing points (apical and intercalary) to increase the number of somatic cells.
What are the tiny grains that make seeds when combined with a flowers eggs?
The tiny grains are pollen, which consists of male reproductive cells. When pollen from a flower's stamen reaches the female reproductive part called the pistil, fertilization can occur, resulting in the formation of seeds.
How does pollen help a seed plant reproduce without water?
Pollen is the male reproductive structure of seed plants. It contains the sperm cells necessary for fertilization. When pollen is transferred from the male reproductive structure to the female reproductive structure (such as by wind or pollinators), it can reach the ovule without the need for water, allowing for fertilization and seed formation to occur.

If the pollen tube does not pass through the micropyle during ovule formation, fertilization cannot occur because the sperm cells contained within the pollen tube will not reach the egg cell. This will prevent the fusion of gametes and subsequently the development of seeds.
Where is the place where pollen lands for pollination to occur in a flower?
Pollen lands on the stigma, which is the sticky female reproductive part of the flower, during pollination. This interaction allows for fertilization and the formation of seeds.
What is the movement of pollen from a stamen to a pistil?
The movement of pollen from a stamen to a pistil is called pollination. This can occur through wind, water, or by animal pollinators like bees, birds, or butterflies transferring the pollen between the reproductive organs of a flower. Once the pollen reaches the pistil, fertilization can occur, leading to the formation of seeds.
What is the significance of the long feathery stigma in the flower?
The long feathery stigma in a flower is the part that receives pollen during pollination. It is essential for fertilization to occur, as it captures the pollen grains for the growth of the pollen tube down to the ovary. This process ultimately leads to the formation of seeds.
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.
What job does a stamen do on a plant?
The stamen is the male reproductive organ of a flower that produces pollen. Its main function is to transfer pollen to the female reproductive organ (pistil) for fertilization to occur, leading to the formation of seeds.
In which part of a plant would meiosis occur?
mitosis occurs in pollen sacs contained in the anther of the stamen and also in the ovule of the carpel. Edited answer: Mitosis takes place at all growing points (apical and intercalary) to increase the number of somatic cells.
What is the reproductive function of a style?
The style in a flower acts as a bridge between the stigma (where pollen lands) and the ovary (containing ovules). It helps facilitate the transfer of pollen to the ovules for fertilization to occur, ultimately leading to seed formation.
What happens when the pollen tube joins the ovule?
If The Pollen Tube Joins The Ovules They Will Have Fertilization And At The End After The Ovules Will Become The Seeds It Is One Or Many Seeds
What is the function of the in-tine in pollen grain?
the in-tine of the pollen grain helps in the nuclear division and probably in the formation of male gametes also.
What name is used when the pollen joins the ovule?
Fertilization occurs when pollen joins with the ovule, resulting in the formation of a fertilized egg or zygote.
