Which of the following statements about bryophytes is correct?

Bryophytes have true stems and leaves like gymnosperms.
Mosses and lichens are the first to colonize bare rocks.
Bryophytes possess vascular tissues for nutrient transport.
All bryophytes grow in dry, arid regions.
2

Mosses, along with lichens, are pioneer species that colonize rocks, aiding ecological succession.

Which of the following statements about mosses is correct?

The protonema in mosses is the sporophyte stage.
Mosses lack rhizoids for attachment to the substrate.
The sex organs in mosses are borne on the leafy shoots.
The sporophyte in mosses is haploid and free-living.
3

Antheridia and archegonia (sex organs) in mosses are produced at the apex of the leafy shoots.

Which class of algae has a cell wall with algin and cellulose?

Chlorophyceae
Phaeophyceae
Rhodophyceae
Xanthophyceae
2

Phaeophyceae (brown algae) have cell walls made of cellulose and algin, a hydrocolloid.

Which type of cell division occurs in the microspore mother cell to form pollen grains in gymnosperms?

Mitosis
Meiosis
Binary fission
Budding
2

In gymnosperms, the microspore mother cell undergoes meiosis to produce haploid pollen grains.

Which of the following statements about pteridophytes is correct?

Pteridophytes lack sporophylls and produce seeds directly.
The prothallus in pteridophytes is a small, multicellular gametophyte.
Pteridophytes have a dominant haploid sporophyte phase.
All pteridophytes are heterosporous like gymnosperms.
2

The prothallus is the inconspicuous, multicellular gametophyte in pteridophytes that bears sex organs.

Which part of the ovule encloses the nucellus and forms the seed coat after fertilization?

Integuments
Funicle
Micropyle
Chalaza
1

The integuments of the ovule develop into the seed coat after fertilization.

Which of the following statements about algae is incorrect?

Algae are simple, thalloid, and autotrophic organisms.
All algae are exclusively marine organisms.
Asexual reproduction in algae occurs via zoospores.
Algae include forms like Volvox and Spirogyra.
2

Algae are not exclusively marine; they occur in freshwater, moist stones, soils, and other habitats too.

Which type of vascular tissue is unique to gymnosperms and absent in angiosperms?

Tracheids
Vessels
Sieve tubes
Companion cells
1

Gymnosperms primarily use tracheids for water conduction, whereas angiosperms mainly use vessels.

Which type of vascular tissue arrangement is found in gymnosperms?

Closed vascular bundles
Scattered vascular bundles
Open vascular bundles arranged in a ring
Vascular bundles with cambium
4

Gymnosperms have vascular bundles with cambium, enabling secondary growth.

Which of the following statements about liverworts is correct?

Liverworts have a sporophyte with vascular tissues.
The sex organs in liverworts are produced on the same or different thalli.
Liverworts reproduce asexually only by spores.
The gametophyte in liverworts is diploid and photosynthetic.
2

Male and female sex organs in liverworts can be on the same thallus or different thalli.
