Pollinationis the first required step in sexual reproduction in plants. The male portion of the plant produces the pollen – typically in the flower. A long filament, called a stamen, holds the bits of pollen at the end and one of several pollinators take the pollen grains to the ...

2. Pollen isn't just produced by flowering plants. "Any plant that has seeds, by definition, also produces pollen," Phillips said. "One of the most interesting things is, the plants that are most plain looking -- weeds, grasses -- tend to cause more allergy symptoms than the big, bea...
controlled. An annual ragweed plant, like either the giant or common ragweed plant, can easily be killed off if it is mowed or chopped down. To help allergy sufferers, mowing down fields of the plants before they flower may greatly help reduce the amount of pollen that is present in the...
What part of the plant does reproduction take place in? Does a female plant produce a female plant when it undergoes asexual reproduction? In the gymnosperm pollen grain, which cell eventually produces the sperm? a. prothallial b. generative c. tube Which plant structure is the dominant sporo...
The Oleander Hawk Moth plays a vital role in the ecosystem. As pollinators, they spread pollen between plants, enabling fertilization and plant reproduction. Their population status directly affects native plant communities, as well as the health of other wildlife that depend on these plants for fo...
The transition from flower to fruit marks a critical phase in the life cycle of a plant. After pollination, the flower's petals typically wilt and fall away as the ovary grows into a fruit. This growth process encapsulates the seeds until they are mature and the fruit is ready for dispersa...
Which part of the plant secretes auxin hormone? What is the alternation of generation in bryophytes (botany)? In the gymnosperm pollen grain, which cell eventually produces the sperm? a. prothallial b. generative c. tube What is the ploidy of a plant gamete? What type of reproduction uses...
It affected many plant and animal groups, both on land and in water. Dinosaurs were only a small part-the disappearance of other living things was so great that scientists knew about the extinction 30 years before the first dinosaur was described. The victims of the Cretaceous extinction ...
You need to have an awareness of the kind of trees you live near or the trees you plant that produces small-sized pollen. Certain trees can become a major allergy problem. It is your understanding of this, in combination with a knowledge of allergy-producing trees, that can help make the...
