|
Definition
| coniferophyta, gnetophyta, ginkgophyta, and cycadophyta |
|
|
Term
| which plants have secondary growth? |
|
Definition
| gymnosperms and angiosperms |
|
|
Term
| which plants have gametophyte dependent on sporophyte? |
|
Definition
| gymnosperms and angiosperms |
|
|
Term
| which plant has sporophyte dependent on gametophyte |
|
Definition
| moss and charophytes(green algae) |
|
|
Term
| which species have archegonium |
|
Definition
| charophyte, moss, fern, some gymnosperms |
|
|
Term
|
Definition
| the equivalent to a leaf in ferns and mosses that bears the sporangia(produces spores) |
|
|
Term
| what species are heterosporous |
|
Definition
|
|
Term
| what is double fertilization and what groups undergo this process? |
|
Definition
| angiosperms do this. 2 sperm cells fertilize the egg forming 1 diploid zygote and 1 triploid endosperm which serves as food source for zygote. |

Term
|
Definition
| agiosperms and gymnosperms |
|
|
Term
| dominant sporophyte stage |
|
Definition
| ferns, gymnosperms, and angiosperms |
|
|
Term
| which groups contain sporophylls? |
|
Definition
|
|
Term
| seed plants with flagellated sperm |
|
Definition
| cycads and ginkgo.. reprsents a transition from water dependent perm transfer of non seed plants and the nonmotile sperm of the rest of the seed plants |
|
|
Term
|
Definition
| strobilus (mega or micro depending on sex) |
|
|
Term
| special characteristic of reproductive ginkgophyta |
|
Definition
| ginkgo lacks female cones but has paired ovules on the tip of the branch |
|
|
Term
|
Definition
| male cone in conifers.. produces microsporphylls which created winged microspores which divide by mitosis into pollen grains (these look like mickey mouse) |
|
|
Term
|
Definition
| female cone in pinus species (conifers) produces megaspores that will form female gametophytes were eggs develop.. depend on sporophyte for nutrition and support |
|
