Biology QUESTION #11129
Question 1
The number of cotyledons in Zea mays (maize), Cycas, and Pinus individually are:
  • 1, 2, 4
  • 1, 2, many✔️
  • 2, 2, many
  • 2, 1, 4
Correct Answer Explanation
  • Zea mays (maize): 1 cotyledon — it is a monocot (class Monocotyledonae)
  • Cycas (cycad, gymnosperm): 2 cotyledons — cycads are considered dicotyledonous gymnosperms
  • Pinus (pine, gymnosperm): many cotyledons (polycotyledonous, typically 3–18, depending on species and conditions) — gymnosperms often have multiple cotyledons
Therefore the correct sequence is 1, 2, many.
