|---|
| vacuole | cell structure where water is stored |
| xylem | transports water & nutrients from root to leaf; woody stem forms rings that indicate the age of a tree |
| stomata | gases pass in and out of plant here |
| phloem | food moves down from leaves |
| cambium | produces new vascular tissue |
| leaf cuticle | reduces evaporation |
| gametophyte stage | when spores that plants produce develop |
| sporophyte and gametophyte | stages of plant life cycle |
| nonvascular plant | thin cell wall; moss, hornworts, liverworts |
| gametophyte | produces egg & sperm during life cycle of a plant |
| vascular plants | have specialized tissue to conduct photosynthesis |
| transpiration | how plants lose water from the leaves |
| amount of darkness | determines time of flowering in many plants |
| root hairs | absorb water and nutrients |
| monocot | angiosperm with oone seed leaf; vascular bundles are scattered; veins are parallel; petals in groups of 3 |
| dormancy | when plant's growth stops |
| cellulose | rigid material in plant cell walls |
| dicot | has two seed leaves; leaves are branched; vascular bundles in rings; petals in groups of 4 or 5 |
