Questions with solutions
Q1 — Angiosperms · easy · theory
Angiosperms are distinguished by having their seeds enclosed within a:
A. Naked ovule
B. Cone
C. Sporangium
D. Fruit (developed from the ovary) ✓ Correct
Solution: In angiosperms (flowering plants) ovules are enclosed in an ovary that ripens into a fruit.
Q2 — Angiosperms · easy · theory
The two classes of angiosperms are:
A. Cycadopsida and Coniferopsida
B. Dicotyledons and Monocotyledons ✓ Correct
C. Bryopsida and Anthocerotopsida
D. Chlorophyceae and Rhodophyceae
Solution: Angiosperms are divided into dicots (two cotyledons) and monocots (one cotyledon).
Q3 — Angiosperms · medium · theory
Double fertilisation, unique to angiosperms, results in the formation of a diploid zygote AND a:
A. Second zygote
B. Diploid endosperm
C. Haploid endosperm
D. Triploid primary endosperm nucleus (PEN) ✓ Correct
Solution: One male gamete fuses with the egg (2n zygote); the other fuses with two polar nuclei forming the triploid PEN — double fertilisation.
Q4 — Angiosperms · medium · theory
The male gametophyte of an angiosperm is the:
A. Pollen grain (germinated pollen tube with two male gametes) ✓ Correct
B. Embryo sac
C. Nucellus
D. Prothallus
Solution: The pollen grain is the highly reduced male gametophyte; the embryo sac is the female gametophyte.
Q5 — Angiosperms · hard · theory
The typical angiosperm female gametophyte (embryo sac) is 7-celled and 8-nucleate, comprising:
A. Four megaspores
B. Only an egg and two synergids
C. Egg apparatus (3), central cell (2 polar nuclei), antipodals (3) ✓ Correct
D. Egg apparatus (5), antipodals (3)
Solution: A mature embryo sac has 3 cells of the egg apparatus, 3 antipodal cells and one central cell with two polar nuclei — 7 cells, 8 nuclei.
Q6 — Angiosperms · hard · theory
Which set of features distinguishes MONOCOTS from DICOTS?
A. Parallel venation, fibrous roots, trimerous flowers, scattered vascular bundles ✓ Correct
B. Reticulate venation, fibrous root
C. Parallel venation, tap root
D. Reticulate venation, tap root, pentamerous flowers
Solution: Monocots: one cotyledon, parallel venation, fibrous roots, trimerous flowers, scattered (closed) vascular bundles.
