Angiospermas plants: what are, characteristics and examples

Angiospermas plants, commonly known as Flower plantsThey are the Vascular plants with seed (spermatophytes) that constitute a really diverse group full of surprising characteristics in terms of the shape and coloration of their flowers.

This fact is mainly due to the close relationship that plants with flowers keep with their pollinators. Whether they are insects, small mammals or natural phenomena such as wind, angiosperms have had to develop a whole series of strategies so that The pollinators They are attracted to their flowers, reach the pollen and subsequently take care of transporting it to the reproductive organs found in other flowers of the same kind of plants, thus achieving the process of plant reproduction.

Angiosperms plants evolved and diversified in a amazing way. The fossil record collects data on the appearance of angiosperms during the Cretaceous period, makes 130 million years approximately.

Among the main characteristics of angiospermas plants stand out:

• They live practically in all regions of the world (although with less presence in polar regions), surviving both in terrestrial ecosystems and in aquatic.
• We can find angiosperm plants of different sizes and structures (shrubs or herbaceous).
• They are constituted by well -differentiated vegetative organs: root, stem and leaves.
• Its flowers are very colorful. They present sepals, tepalos, carpels, and female reproductive organs (ovary with ovules located within the pistil, which has the structure with the style and stigma), as well as male reproductive organs (stamens with pollen grains).

Now that we know its main characteristics, let’s discover some examples of angiosperms plants in the following section.

As we know, all the plants with flowers that inhabit in any corner of the planet belong to the angiosperms group. If we focus, to put some Examples of angiosperms plantsin those that constitute important sources of food for the human being globally, some highlight some fruit cereals and trees as:

• Wheat (genus triticum)
• Corn (Zea mays)
• The rice (ORYZA SATIVA)
• Sugar (gender Saccharum)
• Coffee (Genre Coffea)
• Los Naranjos (genus citrus)
• The apple trees (genre Malus)
• Bananas (genre muse)
• The avocados (American Persea)

The group of angiosperms exceeds that of gymnosperms both in number and diversity, appearing as the group of plants whose evolution has been more successful in nature. Others of the main differences between angiospermas and gymnosperms plants are:

• The formation of Flowers and fruits that surround the seeds in angiosperms, in front of the bare seeds of gymnosperms.
• Gymnosperms have cones, limited growth ramifications that are frequently considered flowers, while angiosperms have colorful flowers that different shapes and colors.
• In gym plants The gametes that intervene in the plant reproduction process, that is, the ovules (female sex) and the pollen grains (male sex), are always separated in different cones (female and male cones, respectively). On the other hand, in the angiosperms plants we can find flowers with ovules in the pistil and pollen in the stamens of the same flower, or exclusively masculine and/or female flowers in the same plant.
• A characteristic common to almost all gymnosperms is that The leaves They are aciculated, pointed or needle -shaped; while angiosperms leaves tend to be flat and more rounded (although with a wide variety of forms).
• Seasonality It is different between these two large groups. Angiosperms plants are usually seasonal plants, expired in autumn and winter, while gymnosperms plants tend to be perennial and do not lose their leaves during cold months.
