Does the stigma in a flower produce pollen?
Pollen is male part of the flower and stigma is the uppermost part of the gynoecium (which is female part). Thus stigma does not produce pollen, rather pollen land on stigma after pollination to fertilize the egg inside the ovary of the flower.
What is the point of the spikiness on the pollen cell?
the spikes present on pollens help it to attach to substrate (like fur of animals, etc )to be transported to the stigma of female flower and thus undergo fertilization
What is the relationship of bee and a flower?
Mutualism - both species benefit from their relationship. The bee comes to the flower to collect nectar as food, and brushes against the anthers of the flower, which are covered in pollen. The bee moves to another flower to collect nectar and rubs the pollen off on the second flower's stigma, fertilizing the flower. Thus, the bee receives a source of food from the flowers, and the flowers are pollinated by the bee.
What does the anther do in the plant?
The anther is the site for synthesis of pollen, the male sex organ in a flower. The pollen grains are transferred from the anther of a male plant to the stigma of a female plant. Thus fertilization takes course.
How does a insect help pollinate a flower?
Insects visit flowers in search of necter and as these collect necter, the pollen grains get stuck to their legs and on visiting another flower these pollen grains are transferred to the stigma of that flower. Thus, pollination is achieved.
The purpose of a pollen grain on a flower?
The purpose of pollen is to transfer the male reproductive cells (sperm) to the female reproductive cells (ovules) and thus to allow sexual reproduction. Pollen can be so transferred by many methods - wind, gravity, insects, etc. The pollen receptive part of the flower (the stigma) is often sticky, or textured so the pollen will stick. Once attached the pollen grain grows a tube into the stigma and down the style into the ovule. This tube allows the male gametes to fertilise the ovule, creating a seed.
How do bees pollinate flowers?
Bees are attracted to flowers by their bright colours and their desire to collect nectar. Nectar tends to be found close to the base of the petals and as the bee attempts to reach it the bee brushes against the male stamens of the flower, which deposit pollen on to its fur. When the bee flies to another flower the same process occurs and some of the pollen which was already present on its fur may brush against the female parts of this flower and then serve to fertilise it.
What is put on the violin bow to make the bow sticky?
Sticky glue
Why don't mushrooms flower?
Mushrooms don't flower because they do not rely on insects for fertilization, and thus have no need to attract them.
Do all flowers have stigmas?
yes all flowers have stigmas. they all need stigmas to live and grow. Stigma is a part of female reproductive organ i.e. Gynoecium in plants. Gynoecium consists of three components namely - Ovary, style and stigma. In plants all the flowers do not have both male and female reproductive parts. Thus exclusively male flowers do not have stigma.
What is the probable relationship between the giant Rafflesia flower and the carrion flies that buzz around it?
***Possible Answer:***The fly is attracted by the "carrion " smell of the Rafflessia flowers, it carries the pollen on its body as it flies from flower to flower, thus helping to pollinate them.
Who was the Catholic saint who wore a glove?
Padre PioRoman Catholic AnswerSt. Pio (commonly know as Padre Pio) had the stigma of Christ, thus he had bleeding wounds in his hands for most of his adult life and thus wore fingerless mittens over the bandages.
