General Characteristic of Pteridophyta
• Pteridophyta is include multicelluler and eucariotic organisms
• Has true root, leaf, and stem (kormophyta/cormus)
• Seed less / have no seed• Sporophyte phase more dominant• Has vascular bundle• Having a vascular bundle (xylem and phloem) • Sexual reproduction in the form of spores • Have a cell protective layer contained around in
the reproductive organs• Have a multicellular embryo contained in
archegonium

Root structure
• Its roots shaped fibers and in the end there is kaliptra (root cap).
• Ferns root tissue is composed of epidermal tissue, cortex and central cylinder
![Page 5: Pteridophyta Wulan Fix](https://reader033.fdocuments.in/reader033/viewer/2022061503/55cf8f33550346703b99e81b/html5/thumbnails/5.jpg)
Stem structure
• Ferns stem tissue composed of epidermis, cortex and central cylinder. At the center of the cylinder there is a network carrier (vascullar bundle), so the ferns already have a transport vessel (tracheophyta).
![Page 6: Pteridophyta Wulan Fix](https://reader033.fdocuments.in/reader033/viewer/2022061503/55cf8f33550346703b99e81b/html5/thumbnails/6.jpg)
Leaf structure
• The leaves of ferns are also composed of epidermal tissues,
mesophyll, and transport vessels (vascular bundle)
![Page 7: Pteridophyta Wulan Fix](https://reader033.fdocuments.in/reader033/viewer/2022061503/55cf8f33550346703b99e81b/html5/thumbnails/7.jpg)
Type Leaf based on size
• Mikrofil leaves, ie leaves ang small size. Mikrofil shaped hair or scales, not stemmed, and invertebrates except the wire nails and horsetail.
• Makrofil leaves, which leaves a large size. makrofil been stemmed, leaves boned, and have the meat leaves (mesophyll) contained stomata, pole network, and sponges.
![Page 8: Pteridophyta Wulan Fix](https://reader033.fdocuments.in/reader033/viewer/2022061503/55cf8f33550346703b99e81b/html5/thumbnails/8.jpg)
Leaf based on function
• Tropofil leaf, ie leaf that does not produce spores, but has a green substance (chlorophyll), thereby functioning in the process of photosynthesis or produce nutrients (glucose). The leaves are often referred to as a sterile leaves.
• Sporofil leaves, ie leaves that produce spores as a means of reproduction (reproduction), so it is also called leaf leaves fertile (fertile).

Sporofil
• Sporofil on ferns exist in the form of strands and some are forming Strobilus. Strobilus is a collection of some sporofil that resembles the shape of a cone.
• At the bottom there sporofil sorus, a collection of small spheres brown box containing many spores (sporangium). At sporangium contained cells resembling cover ring called the annulus.

Sorus is saving by membrane structure that called indusium

Kinds of Pterydophyta based on spores kinds that has resulted
a. Homospora spikes (Isospora)
• Homospora ferns produce spores of the same size that can not
distinguish between male and female spores
• Example: Lycopodium sp. (nail wire)
b. Heterospora spikes (an-Isospora)
• Heterospora ferns produce spores of different sizes. Small spores called
microspores male and female spores are called makrospora
• Example: Selaginella sp. (Nail rane), Marsilea crenata (clover)
c. switching spikes
• Switching spikes produce spores with the same shape and size, but the
male or female sex
• Example: Horsetail (Equisetum debile)

1. Usually used for ornamental plants.2. Some there are who can eat.3. On Azolla pinnata, capable of symbiosis with cyanobacteria, so can be
used as nitrogenous fertilizer.
