How does pollen get from plant to another?
Wind moves pollen for some plants like grass and corn. Animal pollinators move pollen for many flowering plants.
What is the comparison of dandelion to pollen?
Dandelions are flowering plants that produce pollen as part of their reproductive process. Pollen is a powdery substance containing the male reproductive cells of flowering plants like dandelions. Dandelion pollen can be spread by wind or insects to fertilize other dandelion flowers, leading to seed production.
How do seeds Reproduction?
it depends on gymnosperm (naked seed) or angiosperm (flowering plant) this is the angiosperm - Another germination event during the life cycle of gymnosperms and flowering plants is the germination of a pollen grain after pollination. Like seeds, pollen grains are severely dehydrated before being released to facilitate their dispersal from one plant to another. They consist of a protective coat containing several cells (up to 8 in gymnosperms, 2-3 in flowering plants). One of these cells is a tube cell. Once the pollen grain lands on the stigma of a receptive flower (or a female cone in gymnosperms), it takes up water and germinates. Pollen germination is facilitated by hydration on the stigma, as well as the structure and physiology of the stigma and style.[1] Pollen can also be induced to germinate in vitro (in a petri dish or test tube).[3][4] During germination, the tube cell elongates into a pollen tube. In the flower, the pollen tube then grows towards the ovule where it discharges the sperm produced in the pollen grain for fertilization. The germinated pollen grain with its two sperm cells is the mature male microgametophyte of these plants.[1
How is butterfly dependent on flowering plant and a way in which the flowering plant is dependent on the butterfly?
Butterfly is dependent on flowering plants for nectar
What part of the life cycle does a pollen grain represent?
A pollen grain represents the male reproductive cell in the life cycle of a plant. It is the structure responsible for fertilizing the ovules and producing seeds.
What is the sequence of events for reproduction in flowering plants?
Reproduction in flowering plants involves pollination, fertilization, seed development, and dispersal. Pollination occurs when pollen is transferred from the male to the female reproductive organs. Fertilization happens when the pollen combines with the egg cell to form a seed. The seed then develops into a new plant, which can be dispersed through various means like wind, water, or animals.
Are plants flowering or none flowering?
You get both flowering plants and non-flowering plants; non-flowering are things like mosses, ferns and liverworts which produce spore, flowering plants produce seeds
Why are people allergic to grass?
Just like flowering plants, grass gives off pollen. But it's too small to see with the naked eye.
Why do grasses produce many pollen grain?
Like most plants, grass uses sexual reproduction in the form of pollen to grow more. Because this pollen is spread by wind, there needs to be quite a bit of it for the pollen to reliably seed many flowers.
What is pollen formation and where does it occur?
Pollen formation is the process by which male gametophytes develop in seed plants, specifically within the anthers of flowers. During this process, microspores undergo mitosis to form pollen grains, which contain the male reproductive cells. Pollen formation typically occurs in the reproductive structures of angiosperms (flowering plants) and gymnosperms (like conifers) during their respective flowering or cone-bearing seasons. This process is crucial for sexual reproduction, as pollen is transferred to female reproductive organs for fertilization.
How do non-flowering plants pollinate?
Non-flowering plants, such as ferns and mosses, reproduce through spores. Spores are carried by wind, water, or animals to new locations where they develop into new plants without the need for pollination. This method of reproduction is different from the pollen and seeds used by flowering plants.
How is fertilization in flowering plants different from fertilization in other plant groups?
Fertilization in flowering plants is achieved by transferring the male gamete through pollen tube whereas in nonflowering plants the male male gametes are motile and transferred in aqueous medium.
