Which of the following is not a characteristic feature of Bryophytes?

  1. They are non-vascular plants.

  2. They have a gametophyte-dominant life cycle.

  3. They produce spores for reproduction.

  4. They have true roots, stems, and leaves.


Correct Option: D
Explanation:

Bryophytes lack true roots, stems, and leaves. Instead, they have rhizoids, caulidum, and phyllids, respectively.

Which group of Bryophytes is commonly known as liverworts?

  1. Anthocerotae

  2. Bryidae

  3. Hepaticae

  4. Sphagnaceae


Correct Option: C
Explanation:

Hepaticae, also known as liverworts, is one of the three main groups of Bryophytes, along with Anthocerotae and Bryidae.

Which of the following is an example of a thallose liverwort?

  1. Marchantia polymorpha

  2. Riccia fluitans

  3. Anthoceros punctatus

  4. Polytrichum commune


Correct Option: A
Explanation:

Marchantia polymorpha is a well-known thallose liverwort, characterized by its flat, liver-shaped thallus.

What is the dominant phase in the life cycle of Bryophytes?

  1. Sporophyte

  2. Gametophyte

  3. Protonema

  4. Archegonium


Correct Option: B
Explanation:

In Bryophytes, the gametophyte is the dominant phase, meaning it is the longer-lived and more conspicuous phase in their life cycle.

Which structure in Bryophytes produces spores?

  1. Antheridium

  2. Archegonium

  3. Sporangium

  4. Peristome


Correct Option: C
Explanation:

The sporangium is the structure in Bryophytes that produces and releases spores.

What is the function of the peristome in Bryophytes?

  1. It regulates the release of spores.

  2. It provides structural support to the sporangium.

  3. It attracts pollinators.

  4. It absorbs water and nutrients.


Correct Option: A
Explanation:

The peristome is a specialized structure found in the sporangium of Bryophytes. It helps regulate the release of spores by opening and closing in response to changes in humidity.

Which group of Bryophytes is commonly known as mosses?

  1. Anthocerotae

  2. Bryidae

  3. Hepaticae

  4. Sphagnaceae


Correct Option: B
Explanation:

Bryidae, also known as mosses, is one of the three main groups of Bryophytes, along with Anthocerotae and Hepaticae.

Which of the following is an example of a true moss?

  1. Marchantia polymorpha

  2. Riccia fluitans

  3. Anthoceros punctatus

  4. Polytrichum commune


Correct Option: D
Explanation:

Polytrichum commune is a common example of a true moss, belonging to the Bryidae group.

What is the main habitat of Sphagnum mosses?

  1. Temperate forests

  2. Tropical rainforests

  3. Alpine regions

  4. Wetlands


Correct Option: D
Explanation:

Sphagnum mosses are typically found in wetlands, such as bogs, fens, and marshes, where they form peat.

Which of the following is an example of an epiphytic Bryophyte?

  1. Marchantia polymorpha

  2. Riccia fluitans

  3. Anthoceros punctatus

  4. Tillandsia usneoides


Correct Option: D
Explanation:

Tillandsia usneoides, commonly known as Spanish moss, is an epiphytic Bryophyte that grows on trees and other plants.

What is the ecological significance of Bryophytes?

  1. They provide habitat for small animals.

  2. They help in soil formation and erosion control.

  3. They contribute to nutrient cycling.

  4. All of the above


Correct Option: D
Explanation:

Bryophytes play various ecological roles, including providing habitat for small animals, aiding in soil formation and erosion control, and contributing to nutrient cycling.

Which of the following is a conservation concern for Bryophytes?

  1. Habitat loss and fragmentation

  2. Pollution

  3. Climate change

  4. All of the above


Correct Option: D
Explanation:

Bryophytes are facing conservation challenges due to habitat loss and fragmentation, pollution, climate change, and other factors.

What can be done to conserve Bryophytes?
