- Mosses have
-
swimming sperm, sessile egg, and a vegetative gametophyte
- The filamentous stage of mosses which looks like filamentous algae is called
- protonema
- In mosses meiosis occurs in the
- sporangium
- The first plants to appear in the fossil record were

- The life cycle of a bryophyte is
- gametophyte dominant, sporic, and sexual
- "Whisk ferns" belong to the group called
- Psilophytes
- The "lower tracheophytes" consist of plants which have
-
vascular tissue and horizontal stems called rhizomes
- Ferns (pterophytes) have a liverwort-like gametophyte called a
- prothallium

-
the microspore of a pine is produced in
-
microsporangium, staminate cone, sporophyte
-
the megaspore of a pine is produced in
- sporophyte
- female gametophyte of the pine is found
-
in the ovulate cone
-
flowering plants are
- angiosperm
- the microsporangium of a flowering plant known as
- anther
-
Male gametophyte of a typical flowering plant
- only has two nuclei, becomes airborne, forms a pollen tube
