Questions with solutions
Q1 — Pteridophytes · easy · theory
Pteridophytes are the first plants to possess:
A. Flowers
B. Seeds
C. True vascular tissues (xylem and phloem) ✓ Correct
D. Fruits
Solution: Pteridophytes (ferns and allies) are the first terrestrial plants with well-differentiated vascular tissue.
Q2 — Pteridophytes · easy · theory
In the life cycle of a fern, the dominant phase is the:
A. Gametophyte
B. Sporophyte ✓ Correct
C. Zygote
D. Prothallus
Solution: Unlike bryophytes, in pteridophytes the diploid sporophyte is the main, dominant plant.
Q3 — Pteridophytes · medium · theory
The small, multicellular, free-living, mostly photosynthetic gametophyte of a fern is the:
A. Protonema
B. Rhizome
C. Prothallus ✓ Correct
D. Sorus
Solution: Fern spores germinate into an inconspicuous, independent prothallus that bears the sex organs.
Q4 — Pteridophytes · medium · theory
Heterospory — production of two kinds of spores — is seen in:
A. All ferns
B. Dryopteris and Pteris
C. Selaginella and Salvinia ✓ Correct
D. Equisetum only
Solution: Selaginella and Salvinia produce microspores and megaspores (heterospory), a step toward the seed habit.
Q5 — Pteridophytes · hard · theory
The four classes of pteridophytes — Psilopsida, Lycopsida, Sphenopsida, Pteropsida — are represented respectively by:
A. Cycas, Pinus, Ginkgo, Ephedra
B. Psilotum, Selaginella/Lycopodium, Equisetum, Dryopteris/Pteris ✓ Correct
C. Chara, Volvox, Fucus, Ulva
D. Riccia, Funaria, Pinus, Cycas
Solution: These are the standard NCERT type genera of the four pteridophyte classes.
Q6 — Pteridophytes · hard · theory
The significance of heterospory in pteridophytes lies in that the megaspore:
A. Is identical to the microspore
B. Is dispersed by wind only
C. Develops into the sporophyte directly without fertilisation
D. Retains and germinates within it, foreshadowing the seed habit of higher plants ✓ Correct
Solution: In heterosporous forms the female gametophyte is retained on the parent — a precursor to the seed habit of gymnosperms/angiosperms.
