Why plants need pollen and spore?
plants need spores pollen and seeds to reproduce
How does pollen get to the stamen?
Pollen travels through the plants ovaries up to the stamen waiting for a bee to release pollen around.***
What is the adaptive value of the flowers to plants?
The flower attracts a pollinator to the plant, which helps spread the pollen to a different plant, in order to fertilize it.
Explain how animals aid plant reproduction through pollen transport?
Lets start with some definitions- pollen is the male reproductive bit that joins with a female ova of a plant and grows into a fruit that contains seeds, that can grow into plants. Parent plants produce more plants in the process of reproduction. Some plants have male flowers only on male plants and ova only on female plants. Tough for the plants when they try to reproduce because plants can't move the pollen to the ova. So plants need something else to pick up the pollen and place it in the ova. One way this happens is when pollen is carried by wind and floats onto ovas on other plants. Another problem for reproduction happens when the male flower and female flowers are on the same plant, but placed so that pollen does not fall onto a flower with a ripe ova, or pollen is ripe before the ova is ripe and able to be fertilized. Animals such as bees and other insects are attracted to the sweet smell deep in the flower, go in to get the nectar and wind up covered with pollen as they back out. As the bee goes to another flower, the pollen is scraped off as the bee descends into the narrowing flower. When a bee goes from a flower with pollen and delivers the pollen to a ripe ova, it helps the plant reproduce. Also pollen carried from one plant to another plant helps to mix the genes from each plant to the rest of the plants. Its not just bugs that do this. Pollen is also scraped onto the hair or feathers of animals passing by and is carried to other plants where it may fertilize an ova. Without something to move pollen from one plant to another, many plants could not make more plants.
Why do you the stigma is sticky?
The stigma catches pollen and the pollen grain germinate on the stigma. The stigma is sticky to catch and trap pollen with various hairs or flaps.
How does pollen use the air?
Some plants, like grasses and certain trees, do not use insects to carry pollen. Instead they produce large amounts of very small pollen grains which are released into the wind for them to be carried to other plants. Very often, it is this pollen which causes hay fever.
Can some plants use their own pollen to produce seeds?
YES!BECAUSE: Some plants are self-pollinated. That is, the stigma receives the pollen produced within its own flower. In some cases plants receive pollen from other plants; this process is called cross-pollination.
Why do plants use insects to carry pollen?
plantes use insetes to carry pollen cuz thay have no other way to pass pollen so thay use insectes
What are the use of the petals?
to attract to bees so that they can carry the pollen to other plants.
Can heterotroph reproduce?
Yes. Plants have seeds and pollen that they use as a method of reproduction.
Why plants need pollen and spore?
plants need spores pollen and seeds to reproduce
What do plants use the pollen tube for?
A pollen tube is part of the male gametophyte of seed plants. It acts as a conduit to transport the male gamete cells from the pollen grain, either from the stigma (in flowering plants) to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms.
Where is pollen produced in plants?
Pollen is produced in the anthers.
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.
How is the pollen of plants with colorful flowers usually dispersed?
Pollen is dispersed in several ways. Some plants are wind pollinated and the pollen for these is dispersed into the air (e.g. grasses) Some plants use insects (e.g. bees) to transmit their pollen form one flower to the next (e.g. lavender) Some plants use animals (e.g. bats) to transport pollen from one flower to the next (e.g. the Kapok tree) Some plants use birds (e.g. humming birds) to transport pollen from one flower to the next (e.g. the Hibiscus plant)
Why are bees called friends to plants?
Bees collect pollen to make honey, and in doing so they transfer pollen from plant to plant. Pollen contains the sex cells that plants use for sexual reproduction, which provides more genetic diversity than if plants were self-pollinating, or only from within a small area.
How is the pollen cell adapted to it's function?
The pollen is actually nothing but sperm in a protective layer. The pollen is given to various organisms which give to other plants, and then the plants take the fertilization and use it to reproduce, to make fruits, and various other things depending on the species.
