Explain the difference between self-pollination and cross-pollination?
Self-pollination is the inbreeding process occurring in between two flowers of the same plants, in this pollens are transferred from the anthers to the stigma. Cross-pollination is the outbreeding process between the two plants of the same species and of different flowers, in this also the pollens are transfers from the anthers to the stigma.
What is self pollination?
Self pollination is the dropping of pollen on the stigma of the same flower that produced the pollen, thereby pollinating the flower.
What does the ovule develop into when it is fertilized by nectar from another plant?
When an ovule is fertilized by nectar from another plant, it develops into a seed. The nectar acts as a source of pollination, transferring pollen to the ovule, which then goes through fertilization to form a seed.
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.
What is the process of self-pollination?
the pollen goes down to the stamen and the reproduces
How do bees pollenate?
they pollinate flowers by going to a flower and getting the nectar the bee wants and there foot falls into a sac that holds the pollen and the and then when the bee leaves the flower and goes to another flower the pollen falls off the bees foot and starts the pollination process
Is the stamen in the male organ or the female organ in the plant?
The Stamen is the male organ in a plant. It gives off pollen. The pistil is the female organ. The pollen lands in the flower. The pollen then produces a tube that goes to the ovary and fertilizes the seed.
How does pollination take place in flowering plants?
Pollination is the process of transferring male pollen grains to the stigma of the plant (either the same plant = self-pollination, or another related plant close by = cross-pollination). The pollen grains germinate and grow down the style of the plant where the fuse with the female ovules, this results in an embryo being formed, which then becomes the seed of the plant. Pollination is aided by various (so called) "agents" or "vectors", these are things that assist in moving the pollen grains from the anther to the stigma. Vectors/ agents include: wind, insects (bees, butterflies, ants, moths etc.) water in some cases, animals (cats, dogs, sheep, cows, humans etc.)
Why plants produce nectar?
plants have nectar to reproduce. When the insect or bird lands on the plant nectar gets stuck to it. The animal then goes to another plant and spreads the nectar. Then a new plant ts produced. actually, nectar is a sweet liquid produced to attract pollinators (for this example lets say bees, though there are many). The pollen (flower sperm) gets attached to the bees and when they land on another flower, the pollen goes into the stigma (female part of a flower) to produce a seed.
During sexual reproduction in a flowering plant a pollen tube goes down through the?
Style.
What are on the honey bees diet?
they love to collect fluids from flowering plants, pollen, and cross-pollenate by gathering fluid from one plant then it goes to another plant lands and causes some of the fluid to intermingle with the other plant. Ultimately, without bees there will be NO fruit.
