Classifications of Plants Flashcards
These belong to the phylum Pteridophyta, consist of 12,000 species, and can reproduce from spores rather than seeds
Ferns
These are not monophyletic, reproduce by means of exposed cells or ovules, have cones as their reproductive structure, have needle-like leaves, and its seeds are not borne on flower or in fruit
Gymnosperms
This type of gymnosperms have cones as their reproductive structure, have needle like leaves, have 50 genera and 550 species, some are deciduous, and have meristematic tissues that help them grow quickly. An example is pine trees.
Coniferophyta (conifers)
This type of gymnosperms are the second largest group of gymnosperms, have 11 genera and 140 species, have palm-like or fernlike leaves, have a symbiotic relationship with bacteria, and are usually found in subtropical forests and can grow in some desert environments
Cycadophyta (cycads)
This type of gymnosperms have valves to prevent water loss, have been around for 300 million years to 1,000 years, grow in chichi or from a damaged stem or from shoots
Ginkgophyta (ginkgo)
This type of gymnosperms are a small group of vascular seed plants with 70 species divided into three
Gnetophyta/Gnetopsida (ephedra)
This type of Gnetopsida are mostly vines or shrubs, have 30 species, and have broad leaves
Gnetum
This type of Gnetopsida are also called the “Mormon tea”, have 30 species, and undergo double fertilization
Ephedra
This type of Gnetopsida has only one species, the Welwitschia mirabilis, have the largest leaves in the plant kingdom, and can survive in extreme drought
Welwitschia
These are the largest group of plants, have 270,000 species 80% of which are all living plants, pollination as its process of reproduction, and grouped into two Anthophyta
Angiosperms
This type of angiosperm has one embryonic leaf or cotyledon, have 60,000 species, and are herbaceous
Monocot
Orchidaceae, Poaceae, Cyperaceae, Araceae
This type of angiosperm have two embryonic leaves or cotyledons, have 200,000 species, and has a vascular bundle arranged in a ring
