Alternation of generations means that plants produce:
- only haploid multicellular organisms
- only diploid multicellular organisms
- only diploid multicellular organisms with single-celled haploid gametes
- both haploid and diploid multicellular organisms
Which of the following traits of land plants allows them to grow in height?
- alternation of generations
- waxy cuticle
- tracheids
- sporopollenin
How does a haplontic plant population maintain genetic diversity?
- Zygotes are produced by random fusion.
- Gametes are created through meiosis.
- Diploid spores undergo independent assortment during mitosis.
- The zygote undergoes meiosis to generate a haploid sporophyte.
What characteristic of Charales would enable them to survive a dry spell?
- sperm with flagella
- phragmoplasts
- sporopollenin
- chlorophyll a
Which one of these characteristics is present in land plants and not in Charales?
- alternation of generations
- flagellated sperm
- phragmoplasts
- plasmodesmata
A scientist sequences the genome of Chara, red algae, and a tomato plant. What result would support the conclusion that Charophytes should be included in the Plantae kingdom?
- The Chara genome is more similar to the red algae than the tomato plant.
- All three genomes are distinctly different.
- The Chara genome is more similar to the tomato plant genome than the red algae genome.
- The tomato plant genome is distinct from the red algae genome.
Which of the following features does not support the inclusion of Charophytes in the Plantae kingdom?
- Charophyte chloroplasts contain chlorophyll a and b.
- Charophyte plant cell walls contain plasmodesmata to allow transfer between cells within multicellular organisms.
- Charophytes do not exhibit growth throughout the entire plant body.
- Charophytes are multicellular organisms that lack vascular tissue.
Which of the following structures is not found in bryophytes?
- a cellulose cell wall
- chloroplast
- sporangium
- root
Stomata appear in which group of plants?
- Charales
- liverworts
- hornworts
- mosses
The chromosome complement in a moss protonema is:
- 1n
- 2n
- 3n
- varies with the size of the protonema
Why do mosses grow well in the Arctic tundra?
- They grow better at cold temperatures.
- They do not require moisture.
- They do not have true roots and can grow on hard surfaces.
- There are no herbivores in the tundra.
A botanist travels to an area that has experienced a long, severe drought. While examining the bryophytes in the area, they notice that many are in the same life-cycle stage. Which life-cycle stage should be the most common?
