Pollen from the same species is required for successful fertilization because the pollen grains need to contain matching genetic information to that of the female reproductive structures in the flower. This ensures compatibility and proper development of the embryo. Pollen from different species would not have the necessary genetic instructions for successful fertilization to occur.
What else can I help you with?
Can any pollen fertilize any flower?
No, not all pollen can fertilize any flower. For successful fertilization to occur, the pollen must be compatible with the flower's stigma in terms of species and genetic makeup. Pollen from the same species or a closely related species is more likely to be successful in fertilizing a flower.
Pollen must reach an egg in order to?
Pollen must reach an egg in order to fertilize it, allowing the plant to produce seeds for reproduction. This process is essential for genetic diversity and continuation of the plant species.
Why doesva flower have so many pollen grains than ovules?
flowers produce more pollen grains because the anther makes the pollen it then the stigma collects pollen and the petals of flowers atract insects or birds.
Were does pollen comes from?
The stamens which are the male parts produce pollen. It creates in the anther. For an even better answer if the pollen from a stamen travels to the stigma in the same flower it will be know a self pollination. For cross pollination the anther must produce pollen and travel to a different flower's stigma. It is basically self pollination with two flowers.
Why can't flowers pollinate themselves?
1. Many flowers have both male and female parts. So some flowers can indeed pollinate themselves, and the pollen moves from the stamens to the pistil on the same plant. This is called self pollination. Most flowers, however, are cross pollinating. This means the pollen must be carried from the stamens of one plants to the pistil of another plant of the same kind.
Can any pollen fertilize any flower?
No, not all pollen can fertilize any flower. For successful fertilization to occur, the pollen must be compatible with the flower's stigma in terms of species and genetic makeup. Pollen from the same species or a closely related species is more likely to be successful in fertilizing a flower.
What must happen before the fertilization process can happen in pea plants?
The flowers must be open and contain ripe pollen.
what is needed for a flower to make eggs?
In most cases, pollen of a different flower of the same species. Pollen must enter the stigma, where it falls down the style to meet the ovary, which it fertilizes. However, some plants (such as ferns and moss) use spores instead.Flowers make the ovary before blooming on there own, similar to how women are born with eggs in their ovaries.
How do plants with two kinds of flowers make seeds?
Plants with two kinds of flowers, like some species of holly, have male and female reproductive structures on different flowers. Cross-pollination between the two types of flowers is needed for seed production. Pollen from male flowers must be transferred to female flowers to fertilize the ovules and initiate seed development.
Can pollination in pea plants happen in three ways?
Pea flowers are self-pollinating. About two days before the flower even opens, the anthers at the top of the stamen, which are the male part, burst and release the pollen. This sticks onto the stigma and fertilizes the ovary - these are the female parts. In many flowering plants, the stigma will not accept pollen from the same plant and fertilization must occur through other means, such as insect pollination after the flower opens. For gardeners, self-pollination is an advantage as it means more than one type of pea can be grown close together, as cross-pollination will not occur.
What are flowers and how do they work?
Flowers are reproductive organs - they contain stamens (male parts of the flower, loaded with pollen) and stigmas (female parts of the flower, receptive to pollen from another plant of the same species). Plants cannot move, and so they rely on other creatures - normally insects - to move their pollen for them. The insects must be attracted to the flowers so that they will pollinate them. Most of the time, the flowers produce nectar to attract the insects. The bright petals are an advertisement, telling the insects that there is nectar or edible pollen available. Yellow flowers tend to attract insects, while red catches the eyes of most birds. The petals are coloured so brightly because of pigments that are relatively easy for the plant to produce. These pigments can be all colours and combinations of them make the flowers colourful.
Why do bees pollenate the earth?
Bees don't wake up in the morning and think 'I must go and pollinate some flowers today.' They visit the flowers for one purpose only: to get food. They live on nectar and pollen, both of which they get from flowers. In going from flower to flower to collect food they just happen to transfer some pollen from one flower to the next. The flowers give the nectar in order to encourage the bees to visit.

Do all plants need pollinators?
They can't. This is because their pollen cells have different numbers of chromosomes, and therefore reproduction cannot occur. In order for flowers to breed, the pollinator must have the same number of chromosomes in its pollen cells as the flower receiving the pollen.
