T/F? Nodes that are located near the top of a phylogenetic tree represent more recent common ancestors than nodes that are located near the bottom of the tree.
In the moss life cycle ? cells within a sporangium undergo ? to produce ? spores
The most recent common ancestor of all land plants was probably similar to modern-day members of which group
Some green algae exhibit alternation of generations. All land plants exhibit alternation of generations. No charophytes exhibit alternation of generations. Keeping in mind the recent evidence from molecular systematics, the correct interpretation of these observations is that
plants evolved alternation of generations independently of green algae
What is the sequence of structures that develop after germination
Protonema, Gametophore, Gametes, Embryo, Sporophyte
Two, small, poorly drained lakes lie close to each other in a northern forest. The basins of both lakes are composed of the same geologic substratum. One lake is surrounded by dense Sphagnum mat; the other is not. Compared to the pond with Sphagnum, the pond lacking the moss mat should have
What characteristic didn't help seedless plants become better adapted to land
a dominant gametophyte
Flagellated sperm, xylem with tracheids, separated gametophyte and sporophyte generations with the sporophyte dominant, and no seeds. This plant is most closely related to
Which of the following types of plants would not yet have been evolved in the forests that became coal deposits
Arrange structures from largest to smallest: spores, sporophylls, sporophytes, sporangia
Sporophytes, sporophylls, sporangia, spores
Trends in terrestrial vegetation
a trend from dominant gametophytes to dominant sporophytes; a trend from no true leaves, to microphylls, to megaphylls; a trend from soil-surface-hugging plants to 'overtopping' plants; a trend toward increased lignification of conducting systems
What is the sequence in which fossils should make their first appearance? Charophytes, single-celled green algae, hornworts, plants with a dominant sporophyte
single-celled green algae, charophytes, hornworts, plants with a dominant sporophyte
