Where are pollen grains produced?
Pollen grains are produced in the anthers of flowers, which are the male reproductive organs. In the anthers, pollen grains develop and mature before being released for pollination.
What is the other name of stamen?
The other name for stamen is "androecium." It is the male reproductive part of a flower that produces pollen.
What is a ovule part of the female flower?
The ovule is the part of the flower where the embryo sac is housed, and the embryo sac contains the female gamete (egg), which, when fertilized by the sperm in a pollen grain, will produce a zygote. What was once a flower will become a fruit. The zygote develops in the ovule, and forms the seed, which will eventually be dispersed from the fruit to start a new generation. So, the ovule is analogous to the pollen: one contains the female gamete, and the other contains the male gamete.
What is a sac of reproduction cells in yeasts and other sac fungi?
ascus
What are the steps that happen between pollination and fertilization?
1. Germination of pollen grain 2. formation of gametes by pollen mitosis 3. pollen tube elongation across the style reaching the embryo sac/archegonium 4. syngamy (union of male gamete nucleus with the egg nucleus)
What is a pollen-producing sac?
what has a sticky surface where pollen lands
What is the function of the pollen sacs in a flower?
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
What do a anther do in a flower?
The anther holds the pollen sac in Hawaiian flowers or any other kind of flowers.
What does the anthers do in a flower?
The anther holds the pollen sac in Hawaiian flowers or any other kind of flowers.
What is another name for microsporangium?
In seed plants, a spore-producing structure that produces microspores, which can grow to become the male gametopyte is known as microsporangium.
What does the anther do in a Hawaiian flower?
The anther holds the pollen sac in Hawaiian flowers or any other kind of flowers.
What is the function of pollen grains?
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.
Pollen-containing sac that sits atop the filament?
Anther
What are the parts of flowers involved in fertilization?
The female parts of the flower are the ovary, eggs, pollen tube, pistil, and stigma. The male parts of the flower are the stamen, anthers, and pollen. The eggs of the flower are kept in the ovary; pollen from other flowers' anthers and stamens is received by the stigma and filters down through the pollen tube. The pollen fertilizes the eggs; fertilization is complete.
What contains two pollen sacs with pollen grains?
A pollen sac is found in the anther of a flower, which contains pollen grains. Each anther typically has two pollen sacs, known as microsporangia, where pollen grains are produced via meiosis.
Pollen containing sac that sits atop the filament?
The stamen produces pollen, which are the male sex cells of plants. This is then collected into the anther of the stamen.
Does the pollen basket of a bee part collect nectar?
The pollen baskets on a honey bee are specifically for pollen. The bee collects nectar with its tongue and stores it in a sac within its body to transport it back to the hive.
