Questions with solutions
Q1 — Classification of Plants · medium · theory
Simple plants like algae, which lack true roots, stems and leaves, belong to:
A. Pteridophyta
B. Angiosperms
C. Thallophyta ✓ Correct
D. Bryophyta
Solution: Thallophytes (e.g. algae) have an undifferentiated plant body called a thallus.
Q2 — Classification of Plants · hard · theory
Mosses and liverworts, called the "amphibians of the plant kingdom", belong to:
A. Thallophyta
B. Gymnosperms
C. Bryophyta ✓ Correct
D. Angiosperms
Solution: Bryophytes live in moist places and need water for reproduction, so they are called amphibians of the plant kingdom.
Q3 — Classification of Plants · medium · theory
Ferns, which are the first plants to have vascular (conducting) tissue, belong to:
A. Pteridophyta ✓ Correct
B. Thallophyta
C. Bryophyta
D. Angiosperms
Solution: Pteridophytes (ferns) have specialised vascular tissue (xylem and phloem).
Q4 — Classification of Plants · hard · theory
Plants that bear naked seeds (not enclosed in a fruit), such as pine and cycas, are:
A. bryophytes
B. angiosperms
C. algae
D. gymnosperms ✓ Correct
Solution: Gymnosperms produce naked seeds that are not enclosed within a fruit.
Q5 — Classification of Plants · medium · theory
Flowering plants whose seeds are enclosed inside a fruit are called:
A. pteridophytes
B. gymnosperms
C. angiosperms ✓ Correct
D. thallophytes
Solution: Angiosperms are flowering plants with seeds enclosed in fruits.
Q6 — Classification of Plants · hard · theory
Angiosperms are further divided into monocotyledons and dicotyledons based on the number of:
A. cotyledons in the seed ✓ Correct
B. roots
C. leaves
D. petals only
Solution: Monocots have one cotyledon and dicots have two cotyledons in their seeds.
Q7 — Classification of Plants · medium · theory
A plant with seeds having two cotyledons is a:
A. dicotyledon ✓ Correct
B. fern
C. gymnosperm
D. monocotyledon
Solution: Dicotyledons (dicots) have two cotyledons; monocots have one.
Q8 — Classification of Plants · hard · theory
Non-flowering plants that do not produce seeds are collectively called:
A. angiosperms
B. gymnosperms
C. phanerogams
D. cryptogams ✓ Correct
Solution: Cryptogams (thallophytes, bryophytes, pteridophytes) are seedless, non-flowering plants.
Q9 — Classification of Plants · medium · theory
Seed-bearing plants (gymnosperms and angiosperms) are together known as:
A. phanerogams ✓ Correct
B. fungi
C. cryptogams
D. algae
Solution: Phanerogams are seed plants, comprising gymnosperms and angiosperms.
Q10 — Classification of Plants · hard · theory
A parallel-veined leaf and fibrous roots are typical features of a:
A. moss
B. fern
C. monocotyledon (e.g. grass) ✓ Correct
D. dicotyledon (e.g. mango)
Solution: Monocots such as grasses have parallel venation and fibrous roots, unlike dicots.
Q11 — Classification of Plants · easy · theory
The plant kingdom is first divided into two broad groups, cryptogams and phanerogams, mainly on the basis of whether the plants:
A. Live in water or on land
B. Are tall or short
C. Are green in colour or not
D. Produce seeds or not ✓ Correct
Solution: Cryptogams (thallophytes, bryophytes and pteridophytes) are seedless, while phanerogams (gymnosperms and angiosperms) bear seeds. Presence or absence of seeds is the primary basis of this division.
Q12 — Classification of Plants · easy · theory
A plant has a body that is not divided into true roots, stems and leaves, and it lives in water. It most likely belongs to:
A. Pteridophyta
B. Gymnosperms
C. Angiosperms
D. Thallophyta ✓ Correct
Solution: A simple, undifferentiated (thallus-like) body with no true root, stem or leaf, often aquatic (for example algae such as Spirogyra), is characteristic of Thallophyta.
Q13 — Classification of Plants · easy · theory
A gardener finds a plant with parallel-veined leaves and fibrous roots. To which group does it most likely belong, and which is a correct example?
A. Dicotyledons, for example pea
B. Monocotyledons, for example maize ✓ Correct
C. Gymnosperms, for example pine
D. Bryophytes, for example moss
Solution: Parallel venation and fibrous roots are monocot features; maize is a monocotyledon. Dicots instead show net-like (reticulate) venation and tap roots.
Q14 — Classification of Plants · medium · theory
Bryophytes are often called the "amphibians of the plant kingdom". The BEST reason for this name is that they:
A. Possess both gills and lungs
B. Can swim freely in water like fish
C. Grow only deep in the sea
D. Can live on land but still need external water to complete reproduction ✓ Correct
Solution: Like amphibians, bryophytes (mosses and liverworts) live in moist terrestrial habitats but depend on external water to complete their reproduction, hence the name.
Q15 — Classification of Plants · medium · theory
Which of the following arranges the plant groups in order of INCREASING structural complexity?
A. Gymnosperms, Pteridophyta, Bryophyta, Thallophyta
B. Thallophyta, Bryophyta, Pteridophyta, Gymnosperms ✓ Correct
C. Pteridophyta, Gymnosperms, Thallophyta, Bryophyta
D. Bryophyta, Thallophyta, Gymnosperms, Pteridophyta
Solution: Complexity increases from simple thallus algae, to bryophytes (no vascular tissue), to pteridophytes (first true vascular tissue), to gymnosperms (vascular tissue plus seeds).
Q16 — Classification of Plants · hard · theory
Both a pine tree and a mango tree produce seeds, yet they are placed in different groups. The single feature that places the pine in gymnosperms and the mango in angiosperms is that:
A. Pine seeds are naked (not enclosed in a fruit) while mango seeds are enclosed within a fruit ✓ Correct
B. The mango is non-flowering while the pine is flowering
C. The pine is a cryptogam while the mango is a phanerogam
D. Pine has seeds but mango does not
Solution: Gymnosperms bear naked seeds that are not enclosed in a fruit, whereas angiosperms enclose their seeds inside a fruit that develops from the flower. Both, however, are seed plants (phanerogams).
Q17 — Classification of Plants · hard · theory
An unknown plant shows the following features: well-developed vascular (conducting) tissue, reproduces by spores, and bears NO seeds or flowers. The plant belongs to:
A. Pteridophyta ✓ Correct
B. Bryophyta
C. Gymnosperms
D. Angiosperms
Solution: Having vascular tissue rules out bryophytes and thallophytes, while the absence of seeds and flowers rules out gymnosperms and angiosperms. A spore-bearing vascular plant is a pteridophyte, for example a fern.
