Quizplus · Accepted Answer

Gymnosperms have secondary growth, which is the production of new tissues from a lateral meristem. This feature allows them to grow larger and taller than non-vascular plants and some early vascular plants. Choice A is incorrect because gymnosperms do not dominate all land masses today; they are found in many regions but are not the only dominant group. Choice B is incorrect because gymnosperms were dominant during the Mesozoic Era, though they are less diverse and abundant today. Choice D is incorrect because not all gymnosperms have vessel elements; some have tracheids instead. Choice E is incorrect because gymnosperms have sporangia, where they produce their spores.
