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.
-a hollow unicellular or multicellular structure in which spores are produced. characteristics seen in Bryophytes and vascular plants that are NOT seen in charocytes (green algae) -presence of male and female gametangia (antheridia and archegonia) with a protective layer called a sterile jacket layer. -retention of both the zygote and the developing multicellular embryo, or young sporophyte within the archegonium or the female gametophyte. -presence of multicellular, diploid sporophytes.
