| Phylum Bryophyta These are multicellular, eurkaryotes. They have a vascular system. Gametophyte is the dominate generation. They live in moiste enviroments. They lack roots, stems, and leaves. These are the simplest vascular plants and tend to be short. There are 10,000 different speices of this phylum. These are the moses (Sphagnum). Phylum Hepatophyta These are multicellular, eukaryotes. They are avascular. Gametophyte is the dominate generation. They are found in well light, moiste places. They lack vascular tissues, roots, stems, and leaves. They have a flat "leafy" body. There are 6,000 different species of this organism. An example would be liverworts (Marchantia). Phlyum Anthocerophyta These are multicellular, eukaryotes. They are a vascular. Gametophyta is the dominate generation. They are found in well light, moiste places. They are small and flat with no roots, stems, or leaves. There are 100 different speices of this organism, which include hornworts. (Anthocerons). Phylum Psilotophyta These are multicellular, eukaryotes. They have a vascular system. Sporophyte is the dominate generation. They are found in places that get light, and somewhere where they can get water. They are seedless, rootless, and stemless. These plants look are though they are branched. The sporophyta generation does have leaves though. There are 21 different species of this organism. Ex: whisk fern (Psilotum) Phylum Lycophyta These are multicellular, eukaryotes. They have a vascular system. Sporophyte is the dominate generation. These are foud in places where they can get water and have some water. Sporophytes have roots, stems, and leaves. While gametophyte are small and independent. There are 1,000 different speicies of this organism. Ex: club mosses (Lycopodium & Selaginella) Phylum Spenophyta These are multicellular, eukaryotes. They have a vascular system. The sporophyte is the dominate generation. They are found where they have a way to get water and where they get some water. The gametophyta are small and independent. Sporophytes have roots and are seedless. There are 15 different species of this phylum. Ex: Horse tails (Equisetum) Phylum Pterophyta These are multicellular, eukaryotes. They are vascular. Sporophyta is the dominate generation. They are found near some source of water and in well light places. These have roots, stems, leaves, and are seedless. Gametophyta are small and independent. There are 12,000 different speices of this organism. Ex: Salvinia Phylum Cycadophyta These are multicellular, eukaryotes. They are vascular plants. Sporophyta is the dominate generation. They are found in the tropics and subtropics. They look like palm trees. There are 100 different speicies of this organism. Ex: Cycads (Cycas) Phylum Coniferophyta These are multicellular, eukaryotes. They are vascular organisms. Sporophyte is the dominate generation. These have adapted well for cool aired places. They have needles and cones. They are the pines and typical evergreens. There are 550 different species of this organism. Ex: Pinus & Taxus Phylum Gnetophyta These are multicellular, eukaryotes. They are vascular. Sporophyte is the dominate generation. They are found where they get light and water. These grow as a bush, many slender peices of the plant form a bushy apperance. There are 70 different speicies of this phylum. Ex: Ephedra & Wewitschia Phylum Ginkgophyta These are multicellular, eukaryotes. They are vascular. Sporophyta is the dominate generation. They are found where they can get some water and a have a source of light. They are deciduos, with fani like leaves. There is only one speices of the phylum. Ex: Ginkgo biloba Phylum Anthophyta These are multicellular, eukaryotes. They are vascular. Sporophyte is the dominate generation. They are found where they can get water and sunlight. These are a type of flowering plant. There are 25,000 different speices of this organism. Ex: Aster, Prunus, Quercus, & Zea. |
| Nearly all plants reproduce sexually, execpt for those who can do self pollination and ferns that are seedless. |
| Plants started to evolve are 750 million years ago. However some of the more advanced and bigger plants did not evolve until 100 million years ago. |
