Plant traits

The plants are self-sufficient living organisms belonging to the vegetable world that can live on land or in water.
There are over 300,000 species of plants, which produce more than 250,000 flowers. Unlike animals, which need to digest food already prepared, the plants can produce their own food through a chemical process called photosynthesis.

Photosynthesis is basically sugar productionfrom C02 (carbon dioxide) minerals and water with the help of sunlight.
Características de las plantas
Las plantas son organismos vivientes autosuficientes pertenecientes al mundo vegetal que pueden habitar en la tierra o en el agua.
Existen mas de 300.000 especies de plantas, de las cuales más de 250.000 producen flores. A diferencia de los animales, que necesitan digerir alimentos yaelaborados, las plantas son capaces de producir sus propios alimentos a través de un proceso químico llamado fotosíntesis.
La fotosíntesis consiste básicamente en la elaboración de azúcar a partir del C02 ( dióxido de carbono) minerales y agua con la ayuda de la luz solar.

Resulting from this process is oxygen., a waste product that comes from the decomposition of water. Oxygen, which is formed by thereaction between CO2 and water is expelled from the plant through the stomata of the leaves. Photosynthesis to need the energy it takes the plant from the sun. (More information on photosynthesis)
The plants have many different forms, some call them trees, others know them as weeds, others have a bushy, some are known as lianas or just like flowers. According to its height, to softer or harder,as we use them, etc, were called by different names.
Resultante de este proceso, es el oxígeno., un producto de deshecho, que proviene de la descomposición del agua. El oxígeno, que se forma por la reacción entre el CO2 y el agua, es expulsado de la planta a través de los estomas de las hojas. Para hacer la fotosíntesis se necesita la energía que toma la planta del sol. ( Más información sobre lafotosíntesis)

Las plantas presentan formas muy diversas, algunas las llamamos árboles; otras las conocemos como hierbas; otras presentan una forma arbustiva; algunas se conocen como lianas o simplemente como flores. De acuerdo a su altura, a que sean más blandas o más duras , al uso que hacemos de las mismas, etc, las llamamos con nombres diferentes.
Plant evolution
The plants continued toevolve as adding oxygen to the atmosphere. Were able to develop seeds. Seed Plants Spermatophytae call them. The most primitive seed still locked in a fruit and are known as gymnosperms or plants without flowers. "The most advanced plants are angiosperms or flowering plants "which are those that produce seeds.

All these organizations have contributed and continue to contribute to creating theright conditions for life on Earth possible. Thanks to the living things that produce oxygen, not only possible for us to breathe. Also, in an indirect way, these same things have contributed to the formation of ozone, a gas produced by the action of sunlight on oxygen. This layer protects us from harmful ultraviolet rays.
Another consequence of photosynthesis is the reduction of carbon dioxide, agas that, when accumulated raises the temperature of the atmosphere it traps heat from sunlight to produce the famous and fatal "greenhouse effect. "
Plants have protected us for many thousands of "global warming" to absorb excess carbon dioxide. Unfortunately, the combustion of fossil fuels increased levels of this gas so that the plants themselves expectacularmente increasingly less importantin number and variety, are no longer able to solve the problem of an increasingly hot planet.
Evolución de las plantas
Las plantas siguieron evolucionando a medida que añadían oxígeno a la atmósfera. Fueron capaces de desarrollar las semillas. Las plantas con semillas las llamamos espermatofitos. Las más primitivas todavía no encerraban las semillas dentro de un fruto y se conocen como...
