| A | B |
| gymnosperm | first seed producing tracheophytes with seeds on scales or under leaves of plant |
| angiosperm | flowering plants with seeds |
| bryophyte | plants without a vascular system |
| tracheophyte | plants with a vascular system |
| eukaryotic | a cell that has a nucleus |
| seed dispersal | happens through wind, insects, or animals |
| an organism that can make its own food uses this | photosynthesis |
| the waxy, waterproof covering of a plant leaf | cuticle |
| stomata | pours on leaves that allow for the exchange of gases |
| phloem | transports products of photosynthesis throughout plant |
| dicot | seeds have two cotyledons |
| monocot | seeds have one cotyledon |
| parallel veins on leaves | monocot |
| fanned out or net-like veins on leaves | dicot |
| gymnosperm | exposed seeds ("naked" seeds) |
| angiosperm | seeds develop inside fruit |
| cellulose | found in the cell walls of plants |
| reproduction of plants | most sexual, a few asexual |
| sexual reproduction in plants | pollination |
| plants that flower | angiosperms |
| flowers have multiples of 3 petals | monocots |
| flowers have multiples of 4 or 5 petals | dicots |
| transpiration | the loss of water through leaves |
| the needs of plants | sunlight, water & minerals, gas exchange, movement of water & nutrients |
| mosses, liverworts, and hornworts; non-vascular plants; depend on water for reproduction | bryophytes |
| vascular tissue | a system in plants that is specialized to move water and nutrients |
| a structure that holds the entire male gametophyte | pollen grain |
| an embryo of a plant that is encased in a protective covering and surrounded by a food supply | seed |
| surrounds and protects the embryo; keeps the contents of the seeds from drying out | seed coat |
| lacks vascular tissue, plant that absorbs water and other substances directly through its cell walls | nonvascular |
| essential plant nutrients | N, P, K, Mg, Ca |
