Choose the right variant for the multiple-choice statements.
The following is thought to be the group that is the direct common ancestor of most modern plants:
Pyrrophyta (dinoflagellates) b. Chlorophyta (green algae)
c. Phaeophyta (brown algae) d. Rhodophyta (red algae)
e. Euglenophyta (euglenoids).
2. Multicellular algae have
true roots b. true stems c. true leaves
d. considerable tissue differentiation e. none of the above.
3. The simple body form of multicellular algae is called a
thallus b . sporangium c. micropyle
d. cone e. angiosperm.
Because the simple body form of multicellular algae is called a thallus, as a group these organisms are sometimes called
sporantiophytes b. conifers c. angiosperms.
d. algophytes e. thallophytes.
Algal reproductive structures lack
a protective wall of nondividing cells
zygotes that develop into embryos after having been released from the female reproductive organs
a protective wall of sterile cells
all of the above e. none of the above.
Bryophytes include
mosses b. liverworts c. hornworts
d. all of the above e. none of the above.
The vascular plants include
club mosses b. horsetails c. ferns
d. seed plants e. all of the above.
The following are mechanisms that help embryophytes inhabit terrestrial habitats:
embryophytes have multicellular sex organs covered with a layer of protective, sterile cells.
embryophyte sporangia produce spores that are covered with protective sterile cells.
embryophytes have a waxy cuticle that usually covers the aerial parts of the plants.
all of the above e. none of the above.
