Fossil Plants and Plant Kingdom Evolution · NCERT Biology

Which evolutionary trend is evident from fossil records of plants?

  1. Reduction in plant complexity
  2. Shift from land back to water
  3. Progressive increase in complexity
  4. Loss of all reproductive organs
Show answer and explanation

Correct answer: Progressive increase in complexity

Fossil records document a clear progression from simple non-vascular plants to increasingly complex forms with vascular tissues, seeds, and ultimately flowers. This sequential appearance of plant groups supports a pattern of progressive structural and reproductive complexity over geological time.
