| 9111903687 | Charophytes | a type of green algae, are the closest relatives of the land plants(they share a common ancestor) | 0 | |
| 9111918018 | Alteration of generation | multicellular haploid gametophyte alternates with a multicellular diploid sporophyte | 1 | |
| 9111935973 | Multicellular, Dependent embryos | retained within the tissue of the female gametophyte | 2 | |
| 9111945787 | Walled Spores Produced in Sporangia | sporophyte produces spores in organs | 3 | |
| 9111955672 | Multicellular gametangia | Female: archegonia Male: antheridia | 4 | |
| 9111961517 | Apical Meristems | plants sustain continual growth in length by repeated cell division | 5 | |
| 9111969799 | cuticle | waxy covering of epidermis | 6 | |
| 9111975641 | stomata | allow for gas exchange between the outside air and the plant | 7 | |
| 9111993811 | Origin of Plants | about 470 million years ago | 8 | |
| 9111999260 | Origin of vasculature plants | about 425 million years ago | 9 | |
| 9112004917 | Origin of seed plants | about 360 million years ago | 10 | |
| 9112022336 | Why are the bryophytes limited to a small body size? | because they're nonvascular; lack vasculature | 11 | |
| 9112086140 | Which is dominant in bryophytes? | gametophyte | 12 | |
| 9112096296 | What is dominant in the seedless vascular plants, such as ferns? | sporophyte | 13 | |
| 9112104127 | What is the function of the peristome in mosses? | hole that spores are released from | 14 | |
| 9112125433 | Microphylls | small, often spine-shaped leaves with a single vein | 15 | |
| 9112249174 | Megaphylls | larger leaves with a highly branched vascular system | 16 | |
| 9112249175 | Sori | clusters of sporangia on the undersides of sporophylls | 17 | |
| 9112252239 | Homosporous | producing 1 type of spore that develops into bisexual gametophyte | 18 | |
| 9112259454 | Heterosporous | producing 2 different kinds of spores | 19 | |
| 9112266488 | Megaspores | give rise to female gametophytes | 20 | |
| 9112270790 | Microspores | give rise to Male gametophytes | 21 | |
| 9112286576 | Both bryophytes and seedless vascular plants are: | Homosporous | 22 | |
