How do Roses go through pollination?
Insects spread their pollen when they are collecting nectar around and gets pollinated .
How do flowers make seeds and fruits?
By the Wind and the pollen. Because the wind carries the pollen over plants flower and all other things that grow!
Describe how Mendel cross pollinated pea plants?
Gregor Mendel cross-pollinated pea plants by manually transferring pollen from the stamen of one pea plant to the pistil of another pea plant. He carefully removed the anthers from the first plant to prevent self-pollination and then applied the pollen to the stigma of the second plant. This process allowed Mendel to control the genetic makeup of the offspring and study the inheritance patterns of specific traits in pea plants.
What happens to a flower after it is pollinated?
After a plant is pollinated, the pollen grains land on a receptive stigma and germinates, much like how a sperm cell fertilizes an egg cell. This then gives the plant enough chromosomes to produce a seed that can properly grow into a plant as its parents have. Let me modify the above answer a little. The pollen grain carries a little packet of chromosomes, one half of the number in any cell of the parent plant. When the pollen grain lands on the stigma, it does indeed germinate and a long tube grows down the pistil to the ovary--that is what will become the fruit. Many, many pollen grains do this, in fact, at least one pollen grain for each seed. In the ovary are ovules that eventually become seeds. As the pollen tube grows down the pistil, one tube goes to each ovule and one little packet of chromosomes is deposited in each ovule. The ovule has its own little pack of chromosomes, again one half of the number in any cell in the parent plant. These two halves get together and form one new cell that is now a combination of both parents. This cell divides and becomes the embryo in the seed. (If you open a peanut, between the two halves you see a little peanut plant--that is the embryo.) Once the seed begins to grow and develop, phytohormones (plant hormones) are produced which cause the ovary to grow into a fruit which contains the seeds.
How does the location of nectaries help to pollinate the flower?
Pollinators are attracted to the nectar. When they are feeding on the nectar, they pick up pollen and/or deposit pollen. The location of the nectaries is such as to make the pollinators touch the pollen to pick it up or to deposit it.
What flowers that produce much pollen are pollinated?
Flowers that produce much pollen are typically pollinated by insects such as bees, butterflies, and flies. These insects visit the flowers to collect pollen as a food source and inadvertently transfer pollen from one flower to another, aiding in the pollination process.
Why do plants produce more pollen when pollinated by wind?
Plants that are wind-pollinated typically produce a larger quantity of pollen in order to increase the chances of successful pollination by wind, which is less precise than pollination by animals. Wind-pollinated plants rely on producing large amounts of pollen to increase the likelihood of pollen grains reaching another plant of the same species for fertilization.
What is needed to be pollinated and fertilized before they produce seeds?
Ovule needs to be fertilised with sperms from pollen grains to produce seeds
What do cones do?
Male pine cones produce pollen that contains sperm cells. Female cones produce 2 seeds per scale after they are pollinated and then fertilized by the pollen grains.
Why do wind-pollinated plant species generally produce more pollen than animal pollinated species?
They will most likely have less because they are not the kind of flower that really sticks out because of certain coloring, so that's also why they can depend on wing more than animals to pollinate.
Why do flowers pollinated by wind produce lots of dry pollen?
It is because they they are light so they can be blown easily by the wind
Which type of plant causes more hay fever insect pollinated or wind pollinated?
Wind-pollinated plants are primarily responsible for causing more hay fever than insect-pollinated plants. This is because wind-pollinated species, such as grasses, trees, and some weeds, release large quantities of lightweight pollen into the air, which can easily be inhaled by people. In contrast, insect-pollinated plants tend to produce heavier, stickier pollen that is less likely to become airborne and cause allergic reactions. Therefore, individuals with hay fever are more affected by pollen from wind-pollinated plants.
Is a flower pollinated by animals or wind?
Wind-pollinated flowers have many key differences from insect-pollinated ones. Since they don't need to attract insects, wind-pollinated flowers tend to have smaller petals, are odorless, are less colorful, and don't have nectar. Examples are ragweed, corn and wheat.
What do pollinated plants produce?
Pollinated plants produce seeds, which are necessary for the plant to reproduce. Pollination is the process of transferring pollen from the male part of the flower to the female part, leading to fertilization and seed development.
How are sycamores pollinated?
Sycamores are pollinated through the wind. Their flowers produce pollen that is lightweight and easily carried by the wind to fertilize other sycamore trees. Bees and other insects are not typically involved in the pollination of sycamores.
When a flower is pollinated a grain of pollen falls on a what?
When a flower is pollinated, a grain of pollen falls on the stigma, which is the tip of the female reproductive structure called the pistil.
Why do conifers produce more pollen than grains used to fertilize conifer eggs?
Because conifers are pollinated by wind hence to ensure fertilization of each egg clouds of pollen grains are formed.
