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.
Lesson Summary. 1  All plants have a life cycle with alternation of generations. 2  In nonvascular plants, the gametophyte generation is dominant. 3  In vascular plants, the sporophyte generation is dominant. 4  In seed plants, the gametophyte generation takes place in a cone or flower, which forms on the mature sporophyte plant.he flower in Figure above is obviously an innovation in the angiosperm life cycle. Flowers form on the dominant sporophyte plant. They consist of highly specialized male and female reproductive organs. Flowers produce spores that develop into gametophytes.
