Plant Biology 2

7. a filamentous structure that is the earliest stage of the gametophyte in mosses
8. phase in the life cycle of multicellular plants and algae that develops from the zygote; it is the diploid phase after the haploid gametophyte phase.
10. a plant that produces two different types of gametes (usually one large and the other small.)
11. the female reproductive structures typically in homosporous plants (like ferns and mosses)
13. spore case, within which asexual spores are produced.
14. cell with two copies of genetic material (2n)
15. an underground plant stem that grow horizontally and produces the shoot and roots in a plant (also called creeping rootstalk)

1. phase in the life cycle of certain plants and algae that starts with a haploid spore up to the time that gametes are produced.
2. a type of spore from a heterosporous plant that germinates into the male gametophyte (sperm)
3. the male reproductive structures typically in homosporous plants (like ferns and mosses)
4. the alternation of generations with haploid sexual and diploid asexual stages.
5. a type of spore from a heterosporous plant that germinates into the female gametophyte (egg).
6. non-vascular land plants that include mosses, hornworts and liverworts
9. a plant that produces only one kind of spore
12. cell with one copy of genetic material (1n)
