12 Characteristics of Seed Plants (Spermatophyta), Classification, Examples, and ReproductionDilihat: kali
Characteristic feature of seed plants. There are many types and examples of species of plants that are around buddy. In contrast to the moss and nails that may be rare. Therefore, man will be more to know and easy to learn this material.
If you frequently eat any fruit, the seeds are emm..pastinya know where. Inside the fruit is not it? Well, that’s an example of plants that have seeds enclosed. Have also noticed beans buddy, how many pieces? Well, that’s one example of the seed plants into pieces two. Then, what gymnosperm, for example, what?
Well, so my friend does not curious continues, please refer to review material on seed plants that will analyze information about examples of seed plants, classification, reproduction, as well as information about other seed plants.
Seed plants (Spermatophyta)
Seed plants called Spermatophyta, derived from Greek, sperm means the beans and phyta means the plants. This is what makes the seed plants are plants with higher reproductive system. Unlike plants that previously learned that my friend and spike moss, where both species are still breeding with spores.
In my opinion, it is more perfect seed plants, why?
Try to understand more about the explanation pal characteristics of plants mosses and seeds. After the process of reproduction, male and female spores met, whether that will be formed? Yes, of course the forerunner of a new plant in the form of Prototype and there is also protalium. The drawback is that if the environment does not support the new individual candidates could have been dead.
Unlike the seed plants. After the reproduction process, will form the name of the seed. This is the forerunner of a new individual. However, the seeds will not grow until the environmental conditions favor. It means that the seeds can survive for a long time even years, and will grow if it find a safe environment to germinate and grow.
But if all seed plants seeds can grow to form buds? Well, try searching the reference pal. Okay, back to the material.
Seed plants include all plants which produce seeds. Most of the seed plants has significance for humans. Get pal mentioned plants that produce seeds that are consumed by humans? Even most of the seed plants are also covered by fruit tasty meat consumed by humans.
Characteristics of seed plants
Basically seed plants have roots, stems, leaves, flowers also. In general, the characteristics of seed plants is as follows.
- Multicellular organisms
- The cells are eukaryotic (having a nucleus)
- The cell walls are composed of cellulose
- Have chlorophyll
- Autotrof organism, able to produce their own food by photosynthesis
- Already have roots, ty, and true leaves.
- Already have a transporter beam in the form of xylem and phloem
- In general, also has a flower as a reproductive organ
- Do not undergo rotation descent (metagenesis)
- Multiply by seed
- There is a seed that has an open (not wrapped in leaves of fruit), there were seeded closed
- Habitat is mostly on land, but some live in water
Classification of seed plants
Seed plants (Spermatophyta) is currently around 250,000 species of its kind that has the type most widely than mosses and nails.
Seed plants are grouped into two kinds, namely gymnosperm and seed plants closed.
Gymnosperm (gymnosperms) are divided into three classes, melinjo (Gnetinae), class pine (Coniferinae), a class of cycads (Cycadinae), and class Ginkonae.
Closed seed plants (Angiospermae) are divided into two classes, namely dashed one (Monocotyledonae) and dashed two (Dicotyledonae) based on the old classification system. But for a new classification of plants into pieces because no more than two, then there Liliopsida (dashed one) and Magnoliopsida (dashed more than one).

Examples of seed plants
Based on the distribution of seed plants above classification, it can be seen several examples of seed plants that we encountered in the environment around us, including the following.
Gymnosperm (gymnosperms), among others melinjo, pine, cycads.
Closed seed plants (Angiospermae) into pieces one such as corn, rice, coconut, and others. Whereas seed plants closed into pieces two inter alia, mango, guava, rambutan, beans, and others.

Reproduction seed plants
Seeds produced by seed plants produced from the process of pollination (pollen fall on white). After that there will be a process of fertilization (conception), this process will evolve so that the resulting embryos will eventually be formed drupe.
