Questions and Answers
- 1.
What is the scientific name for Liverworts?
- A.
Cycadophyta
- B.
Psilophyta
- C.
Bryophyta
- D.
Hepatophyta
Correct Answer
D. HepatopHytaExplanation
Hepatophyta is the correct answer because it is the scientific name for Liverworts. Liverworts are a group of non-vascular plants that belong to the division Hepatophyta. They are named so because their lobed shape resembles that of a human liver. This group of plants is characterized by their simple structure and lack of specialized tissues for transporting water and nutrients. Therefore, Hepatophyta is the correct scientific name for Liverworts.Rate this question:

In all seedless non-vascular plants, is dominant.
Correct Answer
gametophyteExplanation
In all seedless non-vascular plants, the gametophyte is dominant. This means that the gametophyte generation is the dominant and most visible stage in the life cycle of these plants. The gametophyte is the haploid stage that produces gametes (reproductive cells) through mitosis. In contrast, the sporophyte generation, which is diploid and produces spores through meiosis, is usually smaller and less visible in these plants. The dominance of the gametophyte in seedless non-vascular plants is a characteristic that distinguishes them from seed plants, where the sporophyte is dominant.Rate this question:

Sphagum belongs to which division?
- A.
Bryophyta
- B.
Sphagnopsida
- C.
Anthocerophyta
- D.
Hepatophyta
Correct Answer
B. SpHagnopsidaExplanation
Sphagnopsida is the correct answer because Sphagnum belongs to this division. Sphagnopsida is a class of mosses commonly known as peat mosses, and Sphagnum is a genus within this class. Peat mosses are found in wetland habitats and are known for their ability to retain water. They play an important role in the formation of peat, which is used as a fuel source and in horticulture.Rate this question:

Anthocerophyta has which of the following?
- A.
Stomata
- B.
Roots
- C.
Leaves
- D.
Stems
Correct Answer
A. StomataExplanation
Anthocerophyta is a division of non-vascular plants called hornworts. These plants are small and have simple structures. One of the characteristic features of Anthocerophyta is the presence of stomata. Stomata are small openings on the surface of leaves and stems that allow for gas exchange, including the exchange of carbon dioxide and oxygen. Therefore, the correct answer is stomata, as this is a characteristic feature of Anthocerophyta.Rate this question:

What is the common name for Bryophyta?
Correct Answer
MossesExplanation
Bryophyta is a division of non-vascular plants that includes mosses. Mosses are small, simple plants that lack true roots, stems, and leaves. They typically grow in damp environments and have a low, mat-like appearance. Therefore, the common name for Bryophyta is mosses.Rate this question:
- 6.
Bryophyta are found in .
Correct Answer
moist habitatsExplanation
Bryophyta, which are a group of non-vascular plants including mosses and liverworts, are commonly found in moist habitats. This is because they lack specialized tissues for water conduction and rely on direct absorption of water from their surroundings. Moist habitats provide the necessary moisture for these plants to survive and carry out their life processes.Rate this question:

Marchantia belongs to which division?
Correct Answer
HepatophytaExplanation
Marchantia belongs to the division Hepatophyta. This division includes the liverworts, which are small, non-vascular plants that typically grow in moist environments. Marchantia is a genus of liverwort that is commonly found in damp areas such as gardens, lawns, and forests. It is characterized by its flat, lobed thallus and reproductive structures called gemmae cups. Hepatophyta is one of the divisions of Bryophyta, which also includes the mosses and hornworts. Liverworts like Marchantia play an important role in ecological systems by helping to stabilize soil and providing habitats for small organisms.Rate this question:

What is the common name for Anthocerophyta?
- A.
Liverworts
- B.
Ferns
- C.
Horsetails
- D.
Hornworts
Correct Answer
D. HornwortsExplanation
Hornworts is the common name for Anthocerophyta. Anthocerophyta is a division of non-vascular plants that includes hornworts. Hornworts are small, non-flowering plants that are characterized by their horn-shaped sporophytes. They are found in damp environments and are often found growing on soil or rocks. Hornworts are distinct from liverworts, ferns, and horsetails, which are different types of plants.Rate this question:

Instead of having roots moss has .
Correct Answer
rhizomesExplanation
Mosses do not have roots like other plants. Instead, they have rhizomes, which are horizontal stems that grow along the surface of the ground. Rhizomes help mosses anchor themselves to the substrate and absorb water and nutrients from the environment. Unlike roots, rhizomes do not penetrate deep into the soil. Instead, they spread out horizontally, allowing the moss to grow and colonize new areas. This adaptation helps mosses thrive in moist and shady environments where they can easily attach themselves to rocks, trees, or soil surfaces.Rate this question:

Which divison lacks cuticles, stomata, and leaves?
- A.
Bryophyta
- B.
Pterophyta
- C.
Hepatophyta
- D.
Sphagnosida
Correct Answer
A. BryopHytaExplanation
Bryophyta lacks cuticles, stomata, and leaves. Cuticles are waxy layers that help prevent water loss, stomata are small openings that allow for gas exchange, and leaves are the primary photosynthetic organs in plants. Bryophyta, which includes mosses, liverworts, and hornworts, are non-vascular plants that have simple structures and do not possess these specialized features. They rely on other means for gas exchange and water absorption.Rate this question:

is a subdivision of Bryophyta.
Correct Answer
SphagnopsidaExplanation
Sphagnopsida is a subdivision of Bryophyta. This means that Sphagnopsida is a specific group or category within the larger group of Bryophyta. Bryophyta is a division of non-vascular plants that includes mosses, liverworts, and hornworts. Sphagnopsida specifically refers to the group of mosses known as peat mosses. These mosses are characterized by their ability to retain water and form extensive peatlands. Therefore, Sphagnopsida is a subdivision of Bryophyta that specifically includes peat mosses.Rate this question:

Antheridium is male or female?
- A.
Male
- B.
Female
Correct Answer
A. MaleExplanation
Antheridium is the male reproductive structure in plants. It produces and releases sperm cells, which are necessary for fertilization. This is in contrast to the female reproductive structure, called the archegonium, which produces and contains the egg cells. Therefore, the correct answer is male.Rate this question:
-
- 13.
Archegonium is male or female?
- A.
Male
- B.
Female
Correct Answer
B. FemaleExplanation
Archegonium is the female reproductive organ found in certain plants, including mosses, ferns, and some gymnosperms. It is responsible for producing and housing the female gametes, or eggs, which are necessary for sexual reproduction. The archegonium is typically flask-shaped and consists of a neck and a venter. The neck contains the canal cells and the egg, while the venter contains the neck canal cells and the ventral canal cell. Therefore, the correct answer is female.Rate this question:

is the stalk and the capsule together.
Correct Answer
SporogoniumExplanation
The given correct answer, Sporogonium, refers to the stalk and the capsule together. Sporogonium is a structure found in certain plants, such as mosses and liverworts, where it is responsible for the production and release of spores. It consists of a stalk, known as a seta, and a capsule, which contains the spores. The sporogonium plays a crucial role in the reproductive cycle of these plants, as it allows for the dispersal of spores and the continuation of their life cycle.Rate this question:
