The most recent common ancestor of all land plants was probably similar to modern-day members of which group?
A number of characteristics are very similar between charophytes and members of the kingdom Plantae. Of the following, which characteristic does not provide evidence for a close evolutionary relationship between these two groups?
Cell walls of cellulose, and chloroplasts with chlorophyll. Which of the following characteristics would definitely identify this organism as a land plant?
Which of the following characteristics, if observed in an unidentified green organism, would make it unlikely to be a charophyte?
The zygotes of charophytes may remain within maternal tissues during their initial development. One of the following will not be present, because they are only found in plants.
If you are looking for structures that transfer water and nutrients from a bryophyte gametophyte to a bryophyte sporophyte, then on which part of the sporophyte should you focus your attention?
Flagellated sperm, xylem with tracheids, separate gametophyte and sporophyte generations with dominant sporophyte, and no seeds. This plant is probably most closely related to
Working from deep geologic strata toward shallow geologic strata, what is the sequence in which fossils of these groups should make their first appearance?
This organism has megaphylls, horizontal stem, no seeds, and large leaves with many leaflets. In what Phyla would you place this plant?
Liver-shaped leaf known as thallus, flagellated sperm, and non-vascular. In what Phyla would you place this plant?
