Biology Practice: Classification of Plants (Mock Test 4 - Expert)
1. A scientist discovers a plant that has vascular tissues and produces spores but never produces seeds. In which division should it be placed?
2. Observation of a leaf shows a prominent midrib with a network of smaller veins. If you examine the seed of this plant, how many cotyledons would you expect?

7. In a classification hierarchy, which group contains the largest number of organisms with the fewest shared characteristics?
8. Gymnosperms are called "Xerophytic" in nature because they have:
