Question

How fertilizer occur in flowering plant​

Answer 1

Explanation:

In flowering plants, pollination occurs when pollen grains are transferred from the stamens to the ovules. From the anther the pollen grains are first deposited on the pistil's surface, the stigma. There they germinate and form pollen tubes, which grow downward through the style toward the ovules. Fertilization occurs as a sperm cell in a pollen tube fuses with the egg cell of an ovule, resulting in a plant embryo

Answer 2

• Pollen grains are transmitted from the stamens to the ovules, resulting in pollination in flowering plants.
• Pollen grains are first deposited on the stigma of the pistil, which is made up of pollen grains that come from the anther.
• Pollen tubes grow downward through the style toward the ovules once they germinate.
• When a sperm cell in a pollen tube unites with an ovule's egg cell, a plant embryo is formed.
• We can observe these pollen grains working with a time-lapse camera linked to a microscope.
• Pollen tubes emerge from the grains and go through the pistil to the flower's ovules, getting longer and longer as they do so.
• The sperm cells that will fertilize the egg cells and trigger them to grow into seeds are contained inside the tubes.
