[Campbell Biology P.701] What is a key characteristic of reduced gametophytes in seed plants... | Practice Question

What is a key characteristic of reduced gametophytes in seed plants, as described in the "Five Derived Traits of Seed Plants" table?

  • A: They are macroscopic and independent, performing photosynthesis.
  • B: They are microscopic and nourished by the sporophyte.
  • C: They are the dominant generation in the seed plant life cycle.
  • D: They only produce male gametes, requiring external water for fertilization.

Explanation

The "Five Derived Traits of Seed Plants" table explicitly states that 'Microscopic male and female gametophytes n are nourished and protected by the sporophyte 2n ', which directly aligns with option B.
