Question
Heterosporous plants produce ________ (one/two) type of spores: Homosporous plants produce ________ (one/two) type of spores. A. One and One B. One and Two C. Two and One D. Two and Two Which definition of evolution is correct and complete A. Evolution is the survival of the fittest over generations. B. Evolution is the change in fitness of a species. C. Evolution is the change allele frequencies of a population over generations. D. Evolution is natural selection within a species. What evolutionary advantage would be recognized by separating the gametes as heterosporous plants do? A Greater chance of cross fertilization. B. Higher percentage of reproduction. C. More gametes being produced. D. Less chance of mixing allele frequency within a population. POLYPODIUM-FERN Ferns are homosporous, How does this increase the survival advantage? A. Homosporous species do not have much genetic variation in the population. This can be advantageous in unchanging environments. B. Homosporous species evolve slowly and therefore have no survival advantage. C. Homosporous species can adapt best to radically changing environments. D. If the parent plant thrives in a location its offspring may be at a disadvantage with a very similar genotype. If the environment changes which species has more of an advantage A. homosporous species B. heterosporous species SEED PLANTS The pollen grain is a male gametophyte. In Gymnosperms it travels to the female by A. Wind B. Water C. Insects D. Birds What is not a morphological adaptation gymnosperms have undergone to reduce water loss. A. Developed a thick cuticle.
