Where $a,\ b$ and $c$ are values and $a \neq 0$. Discriminant is given by formula. If $b^{2} - 4ac > 0$ we get two solutions of real numbers. If $b^{2} - 4ac$ = $0$ we get one solution which is a real number. If $b^{2} - 4ac < 0$ we get two solutions of rots of imaginary numbers.
Seed Plants. The sporophyte is also the dominant generation in seed plants. Seed plants are vascular plants that produce seeds and include some nonflowering plants (like pine trees) and flowering plants (like oak trees and roses). So when you see any of these plants, you are looking at the sporophyte. sporophyte is a multicellular diploid generation found in plants and algae that undergo alternation of generations. It produces haploid spores that develop into a gametophyte.
Perhaps you answered green algae to question 1, which would be correct, or charophytes, which are a lineage of green algae and a more precise answer that is also correct. Whatever your response was, modify your answer above to include the other term. We are most interested in those adaptations that are unique to plants and enabled life on land. One trait that is shared with the charophytes is sporopollenin. What is it, and why is it important? Study the four key traits that appear in nearly all land plants but not in the charophytes. You are about to encounter a large new vocabulary.
