2. Bryophytes Do not have true vascular tissues, steam , leaves, nor roots. Produce enclosed reproductive structures (gametangia and sporangia). They don´t produce flower nor seeds, but reproduce via spores. Don´t contain lignin. Are confined to damp shaded areas with high humidity, and frequent rainfall.

3. Bryophytes USE: Pharmaceutical products, in horticulture, as fuel, for household purposes, and are also ecologically important. INTERACTIONS: A taxonomicallydiverse suite of fungiinteractswithbryophytes as pathogens, parasites, saprobes, and commensals.

4. PTERIDOPHYTES Are vascular plants They reproduce only via spores They form two groups: lycopodiophyta and ferns Produce neither flower nor seeds There are 36 species of pteridophytes

5. PTERIDOPHYTES USE: The fronds of the species Drypterisfragransdried and made into tea INTERACTIONS: The azolla contain bleu green alga, which can fix nitrogen from the atmosphere. The fern use this nitrogen to grow and the alga use the excess of carbohydrates.

6. angiosperms They do have showy flower that assure the reproduction of the plant. They have fruits that cover and protect the seeds. Their seeds are developed inside an ovary after pollination. They count with an improved conductive system that makes easy the pass of water and nutrients. The flower has masculine and feminine organ

7. Angiosperms USE: In angyosperms group we’re able to use the "Calendula” which has a yellowish color to gain healthy benefits, this will be helpful for infections and ulcers, also burns and as an anti-inflamatory. INTERACTIONS: The cactus, an angiosperm, use to have a symbiosis interaction of mutualism with insects, it uses to keep water inside it, which will be useful to transfer nutrients and help it’s flowers growth.

8. GYMNOSPERMS USE: Gymnosperms have major economic uses. Pine, fir, spruce and cedar are all examples of conifers which we use for lumber. Some other common uses for them are as soap, varnish, paint, food and perfumes.

9. GYMNOSPERMS Gametophytes became even more reduced in size, often staying within the parent sporophyte plant. Seeds came into being. In general, a seed consists of an embryo sporophyte which has grown from the one-celled zygote, specially packaged “food” to aid in the embryo’s early growth and development, and a seed coat (often derived from structures of the parent sporophyte plant) which is modified for protection and/or dispersal of the seed.
