Practice for Bio Exam 1

which feature is believed to have been the first step in the evolution of land plants from the green algae?

• protection of the embryo

• evolution of vascular tissue

• evolution of microphylls

• evolution of seeds

• evolution of flowers in order to attract pollinators

which structures are found in both ferns and gymnosperms?

• seeds and flowers

• megaphylls and seeds

• microphylls and megaphylls

• flowers and vascular tissue

• megaphylls and vascular tissue

the closest living relatives of land plants are

• charophytes

• chytrids

• sporozoans

• cyanobacteria

• lichens

you discover a green, filamentous multicellular eukaryote growing at the edge of a pond. how could you determine if the organism is a green alga or a plant?

• test for the presence of chlorophylls a and b

• examine the cell walls to see if they are composed of cellulose

• determine if the organism protects and nourishes its embryos.

• see if the organism stores its excess carbohydrates in the form of starch

• determine if the organism protects its zygotes

what structure is a characteristic found only in angiosperms?

• vascular tissue

• seed

• leaf

• flower

• megaphyll

if a plant has vascular tissue, megaphylls, and seeds, but not flowers, then it is a/an

• angiosperm

• gymnosperm

• lycophyte

• fern

• bryophyte

which of the following groups provides protection and nourishment to the embryo?

• angiosperms only

• gymnosperms only

• bryophytes only

• lycophytes only

• all plants

while walking in the woods, you come across some low-growing plants clustered at the base of a tree. you collect one as a specimen for biology class. upon examination in the lab, you find that the leaf-, stem-, and root-like structures contain no vascular tissue. the plant is

• a lycophyte

• an angiosperm

• a gymnosperm

• a bryophyte

• not a plant but a charophyte

which of these is mismatched

• bryophytes - flagellated sperm

• gymnosperm - fruits

• ferns - megaphylls

• lycophytes - microphylls

• angiosperms - seeds

the body of a typical fungus is termed a/an

• antheridium

• mycorrhiza

• mycelium

• hypha

• sporangium
