What is it called when pollen lands on a stigma?
Pollination
What happens once the pollen lands on the stigma?
Pollination
Why do pollen dies if its lands on an unripe stigma?
Pollen grains require a compatible and mature stigma to germinate and grow a pollen tube for fertilization. If pollen lands on an unripe stigma, it may not provide the necessary biochemical signals or nutrients for the pollen to survive and develop. Additionally, the stigma may lack the appropriate receptors or conditions needed for pollen germination, leading to the pollen's eventual death. Ultimately, the failure to establish a successful connection between the pollen and stigma prevents fertilization.
Which part of the pistil is sticky and attracks pollen grains?
anther or stigmaThat depends on what you mean by sticking to. The anther is the part of the plant that is the male organ and it creates pollen. So there is pollen attached to the anther.If you want to know where detached pollen (from the anther) lands to fertilize the egg- then you want the stigma. The sticky pad at the top of the pistil is where the pollen lands to begin creating the pollen tube, which eventually leads to fertilization.
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 is the job of a stigma?
The stigma on a flower is responsible for receiving pollen during fertilization. It is the receptive surface where pollen grains adhere and germinate to produce a pollen tube that delivers sperm to the ovules. This process is essential for sexual reproduction in plants.

What do we call the sticky or hairy part of the flower were the pollen lands?
we call it stigma
What forms when stigma and pollen develop?
When stigma and pollen develop, they enable the process of pollination to occur. The stigma is the part of the pistil that receives the pollen, while the pollen contains the male gametes needed for fertilization. Once the pollen lands on the stigma, it can germinate and grow a pollen tube to transport the male gametes to the ovule for fertilization.
Which structure do pollen grains attach during pollination?
Pollen grains attach to the stigma of a flower's pistil during pollination. The stigma is the receptive part of the pistil where the pollen lands and germinates to form a pollen tube for fertilization 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 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.
What does a stigma do to help make a seed?
A stigma is the part of a flower's female reproductive system that receives pollen during pollination. Once pollen lands on the stigma, it begins the process of fertilization that leads to seed formation. The stigma plays a crucial role in facilitating the transfer of pollen to the ovary of the flower.
What is the delivery of pollen to the stigma of the carpel?
The delivery of pollen to the stigma of the carpel is called pollination. This can occur through various methods, including wind, water, animals, or self-pollination. Once pollen lands on the stigma, it can germinate and fertilize the ovules to form seeds.
