Textbook Question
Chapter 30, Problem 4TYK
Gymnosperms rose to dominance during the
- a. Devonian period, when they successfully competed with the short-statured
bryophytes. - b. Carboniferous period, when they formed important components of the great “coal forests.”
- c. Permian period, when they replaced the seedless vascular plants as the climate became drier.
- d. Mesozoic era, when they replaced
angiosperms as the largest and most widespread group of plants.
