Flowering plants are a type of vascular plant that produces flowers for reproduction, and flowering plants produce seeds in the fruit. The scientific name for flowering plants is seed cassettes. Flowering plants and seed animals consist of two groups of seed plants, flowering plants being the most distinctive feature that distinguishes them from other seed plants and flowers began in the differences between animals. seed-free and developing the evolutionary relationships and open spaces of flowering plants, which ultimately allowed them to control terrestrial ecosystems, Wu The number of flowering plant species in the range of 250,000 to 400,000.

Life cycle of floral plants

The seeds look like children's plants. Their strong outer shell protects the embryo from the inside. Seed germination ends on the ground. Air, water and soil must develop. When the seeds start to grow, we talk about germination. The first growth consists of small roots, then stems grow, then shoots or young plants. When the first sign of life appears above ground, we speak of germination or young plants. The mature plant continues its growth process to become a mature plant with mature leaves, roots and stems. And vinegar The pollination of the flowers produces seeds, and when the seeds finish on the ground, the cycle begins again.

What is Venus?

Flowers are the genitals of floral plants. The main structures of the flower include:

1 – Sibal, Sibal is the support structure of the petal, usually green in color, which helps protect the petal and maintain it. All cups are called together.

2. The petals are colorful leaves of floral flowers, often bright petals and colorful to attract insects that contribute to pollination. All petals are called corolla.

3 – The stamens, which are part of the flower that produces the pollen, and there are two main parts of the chain, namely, barley and charcoal.

4. Al-Shara, is the kasbah that carries the penis.

5 – Anther, the other limb consists of lobes attached to barley and lobes carrying bags containing pollen.

6. The pustule, which is the female part of the flower, contains a carpel.

7. Stigma, an area where pollen is received, may be present at the end of a leg, called a pattern.

8- Carbill, which is the ovary of the flower and contains the oocytes that are potential seeds.

Fruit plants

The fruits are the means by which many plants spread their seeds, and the fruits are formed after the pollination of the flower with the vaccine, the eggs become the seeded seeds and the flower turns into fruit.The seed is the seed. embryo of the plant, a kind of baby plant. The seeds are of all sizes, shapes and colors depending on the type The seeds can be dispersed in different ways, especially in the air, in the water and in animals. Some seeds are light and have hairs or wings that help them float in the air, while others can float on the water and diverge by overlapping. Rivers and streams, no other seeds still have a delicious fruit eaten by animals, and then scattered in animal waste.

Vaccination of plants

In order for the ovary to become a seed, it must receive pollen. Insects and birds can play an important role in pollinating plants. When an insect or bird is attracted to Venus in its bright color, it is subjected to a vaccine. When transferred from one plant to another, to another, it helps the plants to reproduce by creating seeds.

How flora has blossomed the world

Scientists have found an explanation for the very rapid dominance of floral plants in ecosystems around the world, a problem that Charles Darwin called a "mysterious mystery". In a study published Jan. 11 in the open access journal PLOS Biology, Kevin Simonin and Adam Roddy of the University of San Francisco and Yale, respectively, floral plants have small cells for other groups of major plants, and that the volume of this small cell was obtained by significantly reducing the size of the genome. More than 200 years ago, scientists speculated on the diversity and success of spectacular flowering plants. Researchers have shown over the last 30 years that flowering plants have an unparalleled rate of photosynthesis and that they have been allowed to grow faster and overcome the ferns and conifers that dominate ecosystems. hundreds of millions of years.

The secret to the success of floral plant metabolism lies in their specialized leaves that facilitate water transfer rates and faster uptake of carbon dioxide, but the ability of floral plants to create papers capable of withstanding these high levels. perspiration and photosynthesis. The authors argue that these anatomical innovations are directly related to the size of their genome. Since each cell must contain a copy of the genome of the plant, the smaller genome allows the cells to be smaller. If the cells are smaller, more cells can be filled. Specialized in light metabolism, water transfer and diet) in a certain volume, a reduction in the size of each cell can also improve the Efficiency of the distribution of water and nutrients.
