Questions with solutions
Q1 — Kingdom Plantae · easy · theory
Kingdom Plantae includes all eukaryotic organisms that are chiefly:
A. Autotrophic and have cellulose cell walls ✓ Correct
B. Wall-less
C. Prokaryotic
D. Heterotrophic
Solution: Plantae are multicellular eukaryotic autotrophs with chloroplasts and cellulose cell walls (a few, like insectivorous plants, are partly heterotrophic).
Q2 — Kingdom Plantae · easy · theory
Insectivorous plants such as Venus flytrap and parasites like Cuscuta show that some plants are:
A. Partially heterotrophic ✓ Correct
B. Non-photosynthetic always
C. Completely prokaryotic
D. Fungal
Solution: Bladderwort/Venus flytrap are insectivorous and Cuscuta is a parasite — exceptions to pure autotrophy in Plantae.
Q3 — Kingdom Plantae · easy · theory
The life cycle of plants shows an alternation between two phases:
A. Two diploid phases
B. A diploid sporophyte and a haploid gametophyte ✓ Correct
C. Only a diploid phase
D. Two haploid phases
Solution: Plants exhibit alternation of generations between the diploid (2n) sporophyte and haploid (n) gametophyte.
Q4 — Kingdom Plantae · medium · theory
Which storage product and wall material are characteristic of Kingdom Plantae?
A. Starch and chitin
B. Glycogen and chitin
C. Glycogen and cellulose
D. Starch and cellulose ✓ Correct
Solution: Plants store starch and have cellulosic walls, distinguishing them from fungi (glycogen, chitin).
Q5 — Kingdom Plantae · medium · theory
The green algae are now generally grouped with plants (or as ancestral to plants) because they share:
A. Chitin walls
B. Chlorophyll a and b, starch storage and cellulose walls ✓ Correct
C. Prokaryotic organisation
D. Absence of chloroplasts
Solution: Green algae share pigments (chl a, b), starch and cellulose with land plants, indicating a common ancestry.
Q6 — Kingdom Plantae · medium · theory
Which of the following is NOT included in Kingdom Plantae under Whittaker's scheme?
A. Angiosperms
B. Blue-green algae (cyanobacteria) ✓ Correct
C. Gymnosperms
D. Bryophytes
Solution: Cyanobacteria are prokaryotic and belong to Monera, not Plantae, despite being photosynthetic.
Q7 — Kingdom Plantae · hard · theory
In most plants the sporophyte generation is dominant. The exception among the following, where the gametophyte is dominant, is:
A. Ferns
B. Angiosperms
C. Bryophytes (mosses/liverworts) ✓ Correct
D. Gymnosperms
Solution: In bryophytes the haploid gametophyte is the dominant, photosynthetic phase; in higher plants the sporophyte dominates.
Q8 — Kingdom Plantae · hard · theory
The presence of "chloroplasts with chlorophyll a and b" is a defining feature that separates Plantae (and green algae) from:
A. All other autotrophs
B. Fungi only
C. Cyanobacteria only
D. Brown and red algae, which have different accessory pigments ✓ Correct
Solution: Green plants have chl a and b; brown algae have fucoxanthin and red algae have phycoerythrin — different pigment complements.
Q9 — Kingdom Plantae · hard · theory
Which sequence correctly reflects increasing complexity within Kingdom Plantae?
A. Pteridophytes → Bryophytes → Algae → Gymnosperms
B. Bryophytes → Algae → Angiosperms → Gymnosperms
C. Algae → Bryophytes → Pteridophytes → Gymnosperms → Angiosperms ✓ Correct
D. Angiosperms → Gymnosperms → Pteridophytes → Bryophytes → Algae
Solution: This is the standard evolutionary sequence of increasing complexity and adaptation to land.
