AThe root tip
BThe scutellum
CThe endosperm
DThe shoot tip
Answer & Solution
Correct answer: D. The shoot tip
1. A germinating monocot seed puts out two protected structures in turn.
2. The primary root emerges first, protected by the coleorhiza, the covering of the root tip.
3. The primary shoot follows, protected by the coleoptile, the covering of the shoot tip.
4. On exposure to light the coleoptile stops elongating and the leaves expand and unfold.
5. Swapping coleoptile and coleorhiza is the standard slip, since the two names differ only in their endings.
