The plants They are living organisms with complex and extravagant reproduction cycles that can occur without fertilization or vegetatively. These abundant and essential beings in the life of man provide oxygen and allow multiple uses to be created from them.
They have reproductive organs and a fascinating life cycle for all nature lovers. Do you like plant life? Do you know anything about pollination? In OneHowTo we will explain How do plants reproduce and some interesting facts about these organisms on earth.
Plant development
Plants have a complex developmental pattern, containing thousands of microscopic cells, each with a function as well as stems, roots, and reproductive organs.
There are more than 300,000 species of plants, of which the majority are floral, these being the ones that produce the seeds. The flower produces two types of gametophytes, male and female, the female gametophyte arises from a cell within the ovule, a small structure within the ovary of the flower.
The ovary is a larger structure within the flower that usually contains and protects many ovules. Flowering plants are the only ones in which their ovules are totally enclosed in the ovary.
Its reproduction begins with pollination, which can occur through insects or traveling by the wind carrying pollen from one flower to another, causing that when the pollen of a male flower meets a female one, the seeds are produced.
Some flowers are pollinated at night, especially by butterflies, bats, or flies.
Pollinating animals
Each flower can have pollinators, from the small hummingbird, one of the most common pollinators in plants in America, created with a long beak to reach the nectar of flowers. There are also other animals such as bumblebees or bees that pollinate colored flowers, especially those of yellow, purple, blue or white, being attracted by the smell of them, an odor that could be repulsive to the smell of man. Some flowers are also pollinated at night, especially by butterflies, bats, or flies.
Plant reproduction
Plants have various mechanisms to guarantee their offspring: sexual reproduction, which occurs by the fusion of gametes (sex cells) and asexual reproduction, without the fusion of gametes.
The results of sexual reproduction result in plants that are genetically different than their parents. Asexual offspring, on the other hand, obtain genetically identical plants except for the mutation.
For sexual fusion to take place, the pollen grain must be transported to the stigma, which is a receptive platform at the top of the style, an elongated extension at the top of the carpel where the pollen grain germinates.
