You are likely to see the tube cell, vegetative nucleus, generative cell, and the tube nucleus in a pollen tube. This structure can be observed during the process of pollination when the male gametophyte is being transported from the pollen grain to the ovule.
If the stigma of a flower is cut off, it would likely prevent the flower from being pollinated naturally. The stigma is the receptive surface where pollen lands and germinates, leading to fertilization. Without a stigma, the flower would not be able to receive pollen and produce seeds, impacting its reproductive success. Additionally, cutting off the stigma could also disrupt the flower's ability to attract pollinators and reproduce effectively.
If the anther is removed from a flower, it will not be able to produce pollen. The anther is the part of the flower's stamen that contains the pollen grains necessary for reproduction. Without pollen, the flower will not be able to fertilize its ovules and produce seeds, ultimately leading to a lack of fruit or seeds being formed.
"All insects, birds, and land animals (even us) would cease to exist." Incorrect. Flowers weren't around untill 125 millions years ago, making them 300 million years younger than the oldest plants. If flowering plants were to go extinct, non-flowering plants would fill in the niche left by the extinct flowering plants. This would go accompanied by a animal mass-extinction event, caused by the disappearance of the flowering plants that formed a substantial part of the food chain. Short answer: A mass-extinction would follow if flowering plants go extinct. If they never existed, the animal kingdom would never have adapted to flowering plants to begin with.
Stamens and pistils are called essential organs because they are directly involved in the reproductive process of plants. Stamens produce pollen containing the male gametes, while pistils contain the female reproductive parts that receive the pollen and develop into seeds. Without these essential organs, plants would not be able to reproduce.
Yes, you would likely die if you had no bones. Bones provide structural support for the body, protect vital organs, and allow for movement. Without bones, the body would not be able to function properly.
Then the pollen would not be able to reach the ovule therefore it will not be able to make a seed
Yes they can use pollen products. They're completely different.
If pollen from a rose plant reaches the stigma of a carnation flower, fertilization is not likely to occur. Compatibility between different plant species is low due to genetic differences. This will likely result in the pollen not being able to germinate and grow to fertilize the ovules of the carnation flower.

It is likely that they would be able to, depending on the degree of the damage from the collision. Many body shops will be able to order, and install new parts, so it is likely that your local shop will be able to as well.
Dr. Franklin, helped to discover the structure of DNA by doing x-ray crystallography of DNA. The DNA strands gave out a distinctive pattern which Watson and Crick were able to deduce as the helical structure of DNA. Without her picture of DNA, Watson and Crick would not most likely to have figured out the structure of DNA.
It depends. If the pollen that the plat came from is part of the other plant's family, then it is crossbred. However, if not, the pollen will not travel down through the other plant's stigma. Such as a white and red rose will make either a pink or a red rose.
If there was no friction, the pieces of wood nailed together would not be able to stay in place. Without friction, there would be nothing to prevent the pieces from sliding and slipping out of position. Therefore, the structure would likely fall apart.
Poder is the un-conjugated verb for "to be able". So that would most likely be the best verb in this case.
On a Jaguar XJ40, the pollen filters are located behind the glove compartment. To access them, you will need to remove the glove compartment by unscrewing a few screws. Once the glove compartment is out, you should be able to see the pollen filters.
The skeleton provides structure to the human body. Without that structure, you would just be a lumpy mass of skin and goo. I would think that it would be awfully difficult to play football without a skeleton.
