I have been asked this question in examination.

This intriguing question originated from Plant Kingdom in chapter Plant Kingdom of Biology – Class 11

Answer 1

Right choice is (c) Gametophyte depends on the sporophyte

The explanation is: Sporophyte is the dominant phase. All spermatophytes exhibit diplontic life cycle. Gametophyte depends on the Sporophyte. Sporophyte has independent existence and can perform photosynthesis and hence can prepare their own food.
