Q: Answer the following question given this paragraph: One of the two generations of a plant's life cycle is typically dominant to the other generation. Whether it's the sporophyte or gametophyte generation, individuals in the dominant generation live longer and grow larger. They are the green, photosynthetic structures that you would recognize as a fern, tree, or other plant (see Figure below ). Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. Q: Which generation of a plant is generally larger and longer-lived? Choices: - main generation - effective generation - alpha generation - dominant generation A:
A: dominant generation
