What is the gymnosperm?

There are two main classifications of plants carrying seeds: angiosperm and gymnosperm. The main difference between the two lies in the way the plants are reproduced. Angiosperm is a flowering plant and distracts its seeds of fruit. Gymnosperm is a plant that does not have a real flower and does not distract its seed in fruit. The absence of fruits and flowers is what makes a gymnosperm plant. Fruits are often motivations for animals to transfer seeds to other places. When the animal eats fruit, eats the seeds and stores them in another place when they relax. Not so with gymnosperm. Gymnosperms often, although not always, rely on the wind with the fertilization and distraction of its seeds. One of the most famous types of Gymnosperm IS coniferous, in which their seeds are located in cones. In order to reproduce the male structure of the plant, it produces male cones that produce pollen. The pollen is often scattered by the wind to the female part of the plant. The seeds normally develop inside the cone and when mature are dispersed when withE open scale of the cone.

However, the seeds of this type of plant usually do not drop directly to the ground. If they did, new plants would have to compete with their parents to survive. Rather, while the seeds ripen, they develop "wings". In this way, when the seeds are released, they can be transferred by the wind to a new location. Once the seeds cover, the new plant can grow in this place and continue the species.

Most conifers are evergreen and have needles similar to leaves. Some examples of conifers are spent and fir. These types of gymnosperms are also one of the oldest living things on Earth. One type of spruce growing in Sweden was dated for about 9550 years. She survived for so long by adapting to the bushes or tree, according to the climate where she lives.

Not all gymnosperms have needles, develop cones and are evergreen. The Ginkgo biloba (Ginkgo) is a gymnosperm but has a widerleaves and seeds that look like fruit. In addition, it is deciduous, which means that in the autumn it will drop their leaves. The plant is also unique because it is double - that is, it has separate plants of men and women. Many other plants have male and female structures on the same plant.
