The current representatives are very small.

The group is characterized by the sporophyte differentiated into root, stem and leaves.

Depending on the genre may occur hemosperm or heterospory.

Is distributed abundantly in wet tropical regions but are also found in dry air in exposed rocks.

Are commonly known as the fern.

The fern gametophyte is flattened mass.

Commonly stem is represented by a single branched rhizome.

The sporophyte is typically divided into roots, stem and leaves.

In certain regions of some species are used for medicinal, ornamental, fodder and food purposes.

Ferns thrive mostly (80%) and intertropical gloomy wet areas, while the remainder is found in temperate regions.

The life cycle is characterized by an alternation of generations.

REPRODUCTION OF A FERN

Fern leaf spore reproduction zooms.

𝑭𝒆𝒎𝒂𝒍𝒆 𝒄𝒐𝒏𝒆𝒔 𝑴𝒂𝒍𝒆 𝒄𝒐𝒏𝒆𝒔

Be vascular plants because they have inside their stems, woody glasses driving up or carrying crude sap (water and minerals) from the roots to the leaves and falling vessels that carry elaborated sap (food) from leaves to the rest of the plant.

Are tracheophytes plants, as a conduit vessels also are called tracheae, hence its name.

Are spermatophy te plants, as they result from a seed.

Are flowering plants because they have flowers like sexual reproduction organs.

Are cormophytes a plant because they have roots, stems and leaves forming the stem or corm.

Produced fertilization, the eggs processed seeds are fully covered by the ovary become fruit.

In angiosperms, eggs are enclosed within the cavity of the ovary.

Seed provided with a single cotyledon called scutellum.

Hypogeal germination, cotyledons and not emerge from the soil.

Root fibrous and adventitious origin.

Herbaceous or semi-woody stem, usually little branched.

Sessile leaves and usually elongated, with parallel ribs.

Flowers with cycles of 3-6 pieces.

Protective cycles (Calyx and Corolla) are not differentiated and are a perigony.

EXAMPLE

Corn Tulip

Seed having two cotyledons.

Epigeous germination, cotyledons and emerge from the soil surface.

Root or pivotal typical appearance and root or normal origin.

Herbaceous, woody or semi-woody stem, always branched.

Simple or composite leaves, petioles and almost always shaped branched ribbing or retinervadas network.

Flowers with cycles of 4 or 5 pieces.

Protective cycles (Calyx and Corolla) are distinct and form a perianth.

EXAMPLE Bean

 How autotrophic photosynthetic organisms are the base of the food chain, making them a source of food for humans and other animals.

Including flower nectar for bees as an example.

 To be a source of food for humans and other animals have developed many food industries.  Vascular plants supplied materials for the construction industry.  Industries such as textiles (cotton); pharmaceutical and horticulture (gardening, ornamental plants, flowers, botanical gardens).  We also supply most of the wood, cellulosic pulp, paper and materials for shipbuilding industry.  Food Industries as honey production.  Ferns like other vascular plants have ornamental importance.
