| Question | Answer |
|---|---|
| bryophytes | non-vascular plants, require water for reproduction, includes moss, liverworts and hornworts |
| gymnosperm | seed producing plants. We looked at conifers, cycads, and ginkgoes |
| angiosperms | flowering plants |
| cellulose | a substance found in the cell wall |
| embryo | a developing organism |
| autotroph | produce their own food. Plants are autotrophs because they undergo photosynthesis |
| chlorophyll | pigment produced in chloroplasts |
| seed | the embryo in a plant that is surrounded by a food supply |
| flower | structure containing the seeds in angiosperms |
| fruit | tissue walls surrounding the seed |
| cotyledon | first leaf or leaf pair of a plant |
| annual | life span occurs during one growing season |
| biennial | completes life span in two years |
| perennial | lives for more than two years |
| alternation of generation | type of reproduction plants use. The life cycle alternates from the sporophyte generation to the gametophyte generation |
| sporophyte | spore producing plant (2N) |
| gametophyte | gamete producing plant (N) |
| vascular tissue | contains xylem and phloem |
| xylem | tissue that carries water up from the roots to the rest of the plant |
| phloem | tissue that carries nutrients and minerals from the leaves, to the place in the plant where they will be stored |
| rhizoid | root like structures found in moss |
| rhizome | underground stem |
| frond | the leaves of ferns |
| lignin | substance that makes the cell walls rigid, and allows plants to grow upright |
| tracheids | specialized cells in xylem |
| sporangia | spores found on the back of ferns |
| sori | clusters of sporangia |
| male cone | small compared to the female cone, produces pollen |
| female cone | large compared to the male cone, produces the egg to be fertilized |
| seed coat | protective covering of the seed, prevents the seed from drying out |
| pistil | comprised of the stigma, stile, and ovary (female parts of the plant) |
| stamen | comprised of the anther and filament (male parts of the plant) |
| petals | aesthetic part of the flower, used to attract pollinators |
| needles | the leaves of conifers |
| gemmae | reproductive structures in liverworts |
