Their leafy members have tiny appendages in two rows.
Liverworts possess vascular tissues for water transport.
All liverworts grow in dry, sunny habitats.

Which type of spores are produced by the sporophyte of Funaria (a moss) during meiosis?

Haploid
Diploid
Triploid
Polyploid
1

In Funaria, the sporophyte undergoes meiosis to produce haploid spores.

Which classification system first used evolutionary relationships among organisms?

Artificial classification
Natural classification
Phylogenetic classification
Numerical taxonomy
3

Phylogenetic classification considers evolutionary relationships to group organisms.

Which of the following statements about Chlorophyceae is correct?

Chlorophyceae have unequal, lateral flagella like Phaeophyceae.
Vegetative reproduction in Chlorophyceae can occur by spore formation.
Chlorophyceae store food as mannitol and laminarin.
Their dominant pigment is fucoxanthin.
2

Vegetative reproduction in Chlorophyceae can occur by fragmentation or spore formation.

Which class of algae stores food in the form of laminarin?

Chlorophyceae
Phaeophyceae
Rhodophyceae
Xanthophyceae
2

Members of Phaeophyceae (brown algae) store food in the form of laminarin and mannitol.

Which of the following statements about mosses is correct?

The sporophyte in mosses is haploid and produces gametes.
Mosses have rhizoids that are multicellular and branched.
The protonema in mosses develops into a sporophyte directly.
Mosses lack a capsule in their sporophyte.
2

Mosses are attached to the soil by multicellular and branched rhizoids in the leafy stage.

Which of the following statements about Phaeophyceae is incorrect?

Phaeophyceae include simple branched forms like Ectocarpus.
Their gametes are pyriform with two laterally attached flagella.
Phaeophyceae are found primarily in freshwater habitats.
Vegetative reproduction in Phaeophyceae occurs by fragmentation.
3

Phaeophyceae are primarily marine algae, with rare occurrences in freshwater, not primarily freshwater.

Who proposed the natural classification system for flowering plants?

Linnaeus
George Bentham and Joseph Dalton Hooker
Whittaker
Theophrastus
2

George Bentham and Joseph Dalton Hooker proposed the natural classification system for flowering plants, considering both external and internal features.

Which of the following statements about Rhodophyceae is correct?

Rhodophyceae have flagellated spores for reproduction.
Some red algae produce carrageen, a hydrocolloid.
Rhodophyceae store food as oil droplets in pyrenoids.
Their dominant pigment is chlorophyll b.
2

Certain red algae (Rhodophyceae) produce hydrocolloids like carrageen, used commercially.

Which of the following statements about Rhodophyceae is incorrect?

Rhodophyceae reproduce vegetatively by fragmentation.
Their sexual reproduction is oogamous with non-motile gametes.
Rhodophyceae are found in well-lighted surface waters and deep oceans.
The red pigment in Rhodophyceae is chlorophyll d.
4

The red pigment in Rhodophyceae is r-phycoerythrin, not chlorophyll d; they also contain chlorophyll a and d.
