NeetVictoryQuestion 1: Algae and Bryophytes
The brown algae (Phaeophyceae) owe their colour to the pigment:
- A carotene only
- B fucoxanthin
- C chlorophyll b
- D phycoerythrin
Answer: B. fucoxanthin
Why: The cell wall has the cellulose and algin.

Question 2: Angiosperms and Plant Life Cycles
In the alternation of generations seen in plants, the diploid, spore-producing generation is called the:
- A gametophyte
- B sporophyte
- C protonema
- D thallus
Answer: B. sporophyte
Why: The sporophyte is the diploid phase that produces haploid spores by meiosis; these spores germinate into the haploid gametophyte, completing the alternation of generations.
Question 3: Classification of Plants (Algae, Bryophytes, Pteridophytes)
Algae are primarily classified based on the type of:
- A root system
- B pigments, stored food, and cell wall composition
- C flower structure
- D seed type
Answer: B. pigments, stored food, and cell wall composition
Why: Algae are classified into groups (e.g., green, brown, red algae) mainly based on the type of photosynthetic pigments, the form of stored food, and the composition of the cell wall.
Question 4: Gymnosperms and Angiosperms
Pollen grains in gymnosperms such as Pinus are transferred mainly by:
- A insects
- B wind
- C water
- D birds
Answer: B. wind
Why: Large amounts of winged pollen are released, and wind pollination is the rule in conifers.
Question 5: Pteridophytes and Gymnosperms
The roots of Pinus have a symbiotic association with fungi called:
- A a lichen
- B Anabaena
- C Rhizobium
- D mycorrhiza
Answer: D. mycorrhiza
Why: The roots of Cycas have the coralloid roots associated with the N₂-fixing cyanobacteria.
Question 6: Algae and Bryophytes
The reserve food material in the green algae is:
- A starch
- B laminarin
- C mannitol
- D floridean starch
Answer: A. starch
Why: The members of the Phaeophyceae store the laminarin and mannitol.
Question 7: Classification of Plants (Algae, Bryophytes, Pteridophytes)
The artificial system of classification of plants is based on:
- A the DNA sequence
- B the evolutionary relationships
- C the chromosome number
- D a few morphological characters, such as the vegetative and the androecium characters
Answer: D. a few morphological characters, such as the vegetative and the androecium characters
Why: Linnaeus's system was an artificial one.
Question 8: Gymnosperms and Angiosperms
Gymnosperms differ from angiosperms mainly in that gymnosperm seeds are:
- A enclosed within a fruit
- B naked, not enclosed within an ovary
- C absent altogether
- D always found underground
Answer: B. naked, not enclosed within an ovary
Why: The word "gymnosperm" means "naked seed" — their seeds are not enclosed within an ovary/fruit, unlike angiosperm seeds.
