Question #47559
The Question
Read the following statements regarding the establishment and classification of Spermatophytes (seed plants):
Statement I: In all Spermatophytes, the presence of a seed guarantees immediate nutritional independence and autotrophy following radicle emergence, relying solely on endosperm or cotyledonary reserves. Statement II: Pinus seeds cannot germinate and establish without an obligate mycorrhizal association, as the fungal hyphae are essential for phosphorus and water absorption.
Choose the correct option:
Options
- A.
Both Statement I and Statement II are correct.
- B.
Both Statement I and Statement II are incorrect.
- C.
Statement I is correct but Statement II is incorrect.
- D.
Statement I is incorrect but Statement II is correct.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often conflate the evolutionary advancement of the seed habit (Spermatophyte classification) with absolute post-germination autotrophy.
The trap assumes that because Gymnosperms have seeds (and a haploid endosperm), they are entirely self-sufficient.
However, Pinus demonstrates an obligate ecological dependency on mycorrhizae for mineral (phosphorus) uptake to successfully complete germination, bridging Plant Kingdom taxonomy with Plant Physiology.
