liverworts and mosses
You find a green organism in a pond near your house and believe it is a plant, not an alga. The organism is most likely a plant and not an alga if it _____.
contains chloroplasts
is surrounded by a cuticle
does not contain vascular tissue
has cell walls that are comprised largely of cellulose
Stomata _____.
occur in all land plants and define them as a monophyletic group
open to allow gas exchange and close to decrease water loss
occur in all land plants and are the same as pores
open to increase both water absorption and gas exchange
Liverworts, hornworts, and mosses are grouped together as the Bryophytes. Besides not having vascular tissue, what do they all have in common?
They are all wind pollinated
They are heterosporous
They can reproduce asexually by producing gemmae cup
They require water for reproduction
Which of these are spore-producing structures?
sporophyte (capsule) of a moss
antheridium of a moss or fern
gametophyte of a moss
archegonium of a moss or fern
How are the bryophytes and seedless vascular plants alike?
Plants in both groups have vascular tissue.
In both groups, sperm swim from antheridia to archegonia.
The dominant generation in both groups is the sporophyte.
Plants in both groups have true roots, stems, and leaves.
Archegonia _____.
are the sites where male gametes are produced
may contain sporophyte embryos
have the same function as sporangia
make asexual reproductive structures
Which of the following is true of the life cycle of mosses?
Spores are primarily distributed by water currents
The haploid generation grows on the sporophyte generation
Antheridia and archegonia are produced by gametophytes
The sporophyte generation is dominant
What is heterosporous?
Male and female reproductive structures are located on separate plants
Male and female reproductive structures are located on same plant
It has multiple sporangia
Its diploid sporophyte produces spores via meiosis
A botanist discovers a new species of plant in a tropical rain forest.
