Plant classification

Bryophyta Roots that anchor the gametophyte and lacks vascular tissue Haploid gametophyte that is composed of roots, stem and leaves; it lacks vascular tissue and therefore requires moist environment to survive; it bears male and female reproductive organs Haploid gametophyte that is composed of roots, stem and leaves; it lacks vascular tissue and therefore requires moist environment to survive; it bears male and female reproductive organs Diploid sporophyte that is dependent on the gametohyte and bears haploid spores; spores germinate to form new gametophyte Diploid sporophyte that is dependent on the gametohyte and bears haploid spores; spores germinate to form new gametophyte

Pterophyta Sori on the undersurface of the leaflets - contains sporangia with haploid spores Fiddlehead - uncurling of the frond Diploid sporophyte is composed of horizontal stem with roots and large leaves (fronds); the leaflets bear sori on the undersurface that has sporangia with haploid spores; spores germinate to form haploid gametophyte that is microscopic and bears male and female gametes

Coniferophyta The plants are diploid sporophytes that bear cones with seeds Cones that bear haploid gametes and eventually diploid seeds are formed

Anthophyta Sepals Seeds Seeds Fruit - encloses seeds Fruit - encloses seeds Anther - bears pollen grains Anther - bears pollen grains Filament Filament Style Style Ovary Ovary Petals Petals The plants are diploid sporophytes that bear flowers, fruits and covered seeds

Anthophyta flowers Petal Filament Style Anther - bears pollen Ovary Ovule Style Stigma Filament Anther - bears pollen Petal Sepal
