seeds and vascular tissue, woody plants that produce seeds, but their seeds are not enclosed in fruits
flowering plants that produce seeds in fruit
a group of biological taxa or species that share features inherited from a common ancestor
monocots 4 traits
1 cotyledon, parallel veins, scattered vascular tissue, fivrous roots
2 cotyledons, net-like veins, circular arragnement of vascular tissue, tap root,
first leaf or first pair of leaves produced by the embryo of a seed plant
what do both eudicots and monocots have in common?
presence of flowers and fruits
Seed bearing structure of an angiosperm.
a leaflike structure that encloses the bud of a flower.
modified leaves which are usually bright in color to attract pollinators.
the male reproductive organ of a flower
end of stamen that contians sporangium of male
innermost part of a flower that produces the female gametophytes
leads to ovary
develop into seeds
the organ that bears the ovules of a flower
mature ovary of a flower
deveolp from ovules
protects seeds and aids dispersal
major trends in plant evoultion (5)
1. decrase dominance of gametophyte, incerase dominance of sporophyte
2. devleopment of vascular tissue
3. decrease dependence on water for fertilization
4. seed as a resistant dispersible stage of life cycle
5. pollen as a resisstant structure for dispering sperm gametes
Impact of seed plants (4)
1. major food crops
2. production of wood
3. natural products
4. made air habitible for life
