Kingdom Plante • Multicellular, Eukaryotic, Cell wall made of cellulose, Autotrophs, not capable of movement, reproduce sexually some produce spores and others seeds. • Most have vascular tissues which include roots, stems, and leaves, and specialized tissues called xylem and phloem.
Spore Producing Divisions of Plant 9 Divisions of Plants: Spore producers • Bryophytaonly nonvascular plants, ex moss and liverwort (gametophyte dominant stage of life cycle know as alternation of generations) • Lycopodophytaex. 1,000 species of Club and Spike moss • Sphenophytaex. 10 species of Horsetails • Filicinophytaex 11,000 species of Ferns (sporophyte dominant stage)
Seed producers • Gymnosperms: reproductive structure is the cone , “naked seed” • Cycadophyta200 species of these tropical plants • Ginkgophyta 1 species remains the Gingko tree • Coniferophyta 600 species of conifers, pine, spruce, cypress, juniper, fir • Gnetophyta 70 species of these arid/semi-desert dwelling plants
Seed producers Angiosprems- reproductive structure is the flower, seeds are surrounded by fleshy or dry fruit that ripen to encourage animals to disperse the seeds. 30,000 or more identified species maple, hickory, oak, aloe, roses, tulips, dogwood, magnolia, corn, beans, tobacco, apple tree, pecan tree 2 classes: Monocots – with one seed leaf or cotyledon and parallel veins on the leaf, orchids, lilies, grass, corn, grains Dicots- with two seed leafs and branched veins on the leaf, roses, peas, beans, and oaks
Seed producers- gymnosperms “Cone Bearers”
Flowering Plant images • Produce flowers and fruits (fleshy or dry)
Dry and Fleshy fruits • Fruit is the mature ovary of the flower. • It surrounds the seed and is often used to promote seed dispersal. • Animals eat the fruit and seed and poop it somewhere else, this reduces competition with the parent plant.
Parts of a Flower • Pollination- fertilization of the female gamete by the male gamete • Flowers are designed to attract a pollinator, either by color, smell, or offer of food. • Birds, insects, and mammals act as pollinator
Other Plant Info. Symbiotic relations ships: • Plants and Nitrogen fixing Bacteria • Flower patterns and scent attract pollinators • Fruits promote seed dispersal by offering a sweet reward to animals.
Plant Adaptations: • Tropism- plant activities controled by hormones • phototropism (light), geotropism (gravity), and thigmotropism (touch) • specialized leaves (needles, spines, fuzzy, waxy) help reduce water loss (transpiration) in arid environments
