- A Seeds germinate almost immediately upon release from the parent plant with very little delay as frequently described in most textbook accounts
- B Seeds are stored in cones or fruits and released only after a specific trigger such as fire (e.g., lodgepole pine, Banksia)
- C Fruits develop and reach full maturity without any prior fertilization event ever taking place during normal conditions
- D Pollen is released from the anther mainly during the late nighttime hours specifically as generally observed in typical laboratory settings
Correct answer: B. Seeds are stored in cones or fruits and released only after a specific trigger such as fire (e.g., lodgepole pine, Banksia)
Explanation: Serotiny: seeds sealed in fire-adapted cones or fruits (by resin). Fire melts resin, releasing seeds onto ash-enriched, competitor-free soil. Adaptation to fire-prone environments.
