Biodiversity, plants & animals Hard

Consider the following pairs:

PlantDescription
I.CassavaWoody shrub
II.GingerHerb with pseudostem
III.Malabar spinachHerbaceous climber
IV.MintAnnual shrub
V.PapayaWoody shrub

How many of the above pairs are correctly matched?

Answer & explanation

Answer: (b) Only three

Cassava (woody shrub), ginger (herb with a pseudostem) and Malabar spinach (climber) are matched correctly. Mint is a herbaceous perennial, not an annual shrub, and papaya is a tree-like herb, not a woody shrub. That makes three correct pairs.

  • ✓ I FAO describes cassava as a woody perennial shrub that grows 1 m to 5 m tall.
  • ✓ II Ginger is a slender perennial herb; its leafy shoot is a pseudostem formed by the leaf sheaths, not a true stem.
  • ✓ III Malabar spinach (Basella) has soft, succulent, branched climbing stems, so it is a herbaceous climber.
  • ✗ IV Mint is a herbaceous perennial that spreads by stolons; it is a herb, not a shrub.
  • ✗ V FAO calls papaya a fast-growing tree-like herb, so it is not a woody shrub.

Remember · Cassava = woody shrub; ginger = herb with a pseudostem; Malabar spinach = climber; mint = herbaceous perennial; papaya = tree-like herb (not woody).
