28 Questions
Which of the following is a characteristic of bryophytes?
Their gametophyte phase is larger and longer living than the sporophyte.
Which of the following is a characteristic of seedless vascular plants?
They have flagellated sperm.
What is the function of the foot in the sporophyte of bryophytes?
It absorbs nutrients from the gametophyte.
What is the function of xylem in vascular plants?
It conducts water and minerals.
Which of the following is true about the gametophyte phase of seedless vascular plants?
It is shorter-lived and independent of the sporophyte phase.
What is the function of rhizoids in seedless vascular plants?
To anchor the gametophyte to a substrate.
What is the ecological relevance of ferns?
They are used as air filters.
Which type of plants have specialized pores on leaves called stomata?
Angiosperms
Which phase of the plant life cycle produces spores through meiosis?
Sporophyte stage
Which type of plants have flagellated sperm that swim to the archegonia for fertilization?
Bryophytes
Where are apical meristems found in plants?
Roots and shoots
Which of the following traits are specialized and unique to plants that did not exist in previous ancestors?
Alternation of generations and walled spores
Which of the following is a structure involved in cell plate formation and subsequent division of daughter cells, found in certain Charophytes and plants only?
Phragmoplast
Which of the following is a trait shared by Charophyte green algae and plants?
Cellulose synthesizing proteins
True or false: Phloem transports sugars, amino acids, and other organic products.
True
True or false: The gametophyte phase of seedless vascular plants is longer-lived and independent.
False
True or false: Rhizoids in seedless vascular plants are used to anchor the gametophyte to a substrate.
True
True or false: Charophyte green algae and plants share the same structure of flagellated sperm.
True
True or false: Cuticle is a specialized trait unique to plants that did not exist in previous ancestors.
True
True or false: Sporopollenin prevents the zygote from drying out in charophytes and plants.
True
Non-vascular plants (bryophytes) have true roots for water and mineral absorption.
False
The sporophyte stage is dominant in the life cycle of seedless vascular plants.
True
Bryophytes produce both sperm and egg in separate gametangia.
False
Vascular plants have specialized pores on leaves called stomata.
True
True or false: Stomata are specialized pores on leaves that support photosynthesis by allowing gas exchange of O2 taken in the outside air and release of CO2 (CO2 is a bi-product of photosynthesis).
False
True or false: The gametophyte stage is a diploid, multicellular stage of the plant life cycle that produces spores by meiosis.
False
True or false: Sporangia are organs found in the sporophyte stage that produce spores through asexual reproduction.
False
True or false: Bryophytes, lycophytes, and monilophytes are examples of nonvascular plants.
False
Test your knowledge of non-vascular plants (bryophytes) and their different phylums, including liverworts, hornworts, and mosses. Explore the characteristics of bryophytes, with a focus on the dominant gametophyte phase. Challenge yourself with questions about protonema and other key aspects of these fascinating plants.
