Anthophyta • consists of flowering plants - the pistil - the stamen - petals

• importance - attract pollinators - ovules are protected inside ovary. - ovary develops into fruit which foster the dispersal of seeds by: wind, insects, birds, mammals, and other animals.

Coniferophyta• include pines, firs, spruces, junipers, redwoods, cedars, etc.• borne in pollen bearing male cones and ovule bearing female cones.• conifers make up a group called the gymnosperms.

Bryophytes

Mosses

Liverworts

Hornworts

Consist of 3 groups of unspecified plants:Mosses- its a flowerless, leafy stemmed plant that reproduces by spores & growing on turfs or mats on moist ground or rocks.Liverworts- any moss-like plant that grows on rock or tree trunks in order to decay them. Hornworts- aquatic plants living in ponds and slow streams

Bryophytes

The gametes are produced in protective structures called gametangia. It's the dominant stage of the Bryophytes' life cycle.Male gametangium (antheridium) produce flagellated sperm that swim to the water to the fertilized eggs of the archegonium (female). Zygote grows while attached to the gametophyte.A capsule contains haploid spores produced by meiosis. Spores are dispersed by wind, germinated,& grow into Haploid gametophytes. They don't have true: roots, stems or leaves, because of not having specialized vascular tissue xylem or phloem.They must remain small and water must be available for absorption through the surface tissues and for reproduction.

Lycophyta

● Small common group of plants that include:○ Club Mosses○ Spike Mosses○ Quillworts

● Microphylls:○ Type of leaf that has evolved from leaves of

other vascular plants○ Has a single strand of vascular tissue (An unbranched

vein)● Strobili:

○ Leaf-like structure on a plant and produces spores○ Commonly called cones because it has a central axis

(middle core) with leaf and stem like forms that surround core that makes it look like a cone

Seed Travel & Pterophyta

(left) an example of a type of seed that travels by wind.

(right) shows that seeds can land and grow on trees. The tree is being a host to several other plants.

Pterophyta: ferns are in the background of the image to the left. Ferns produce clusters of sporangia called sori, that develope on the undersurface of fern fronds. The sporangia undergo meiosis and produce the spores.
