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.
How does the sticky tip of the pistil help a plant reproduce?
The sticky tip of the pistil, known as the stigma, plays a crucial role in plant reproduction by capturing pollen grains from the air or from pollinators. This sticky surface ensures that pollen adheres effectively, allowing for successful fertilization. Once pollen lands on the stigma, it germinates and grows down the style to reach the ovary, where fertilization occurs, leading to seed development. Thus, the stigma facilitates the transfer of genetic material necessary for the production of new plants.
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.
Makes seeds when combined whit a flower's eggs?
The process of making seeds when combined with a flower's eggs refers to fertilization in plants. During fertilization, pollen from the male part of a flower (anther) transfers to the female part (stigma) and travels down to the ovary, where it merges with the ovules (flower's eggs). This fusion produces seeds, which contain the genetic material necessary for the development of a new plant. Thus, seeds are formed as a result of this reproductive process.
Does the carpel contain the eggs in a flower?
Yes, the carpel, which is the female reproductive part of a flower, contains the ovules, which develop into eggs. The carpel consists of three main parts: the stigma, style, and ovary. The ovary holds the ovules, and when fertilization occurs, the ovules develop into seeds. Thus, the carpel plays a crucial role in reproduction in flowering plants.
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.
