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.
Comments. Submit. Seed plants---or spermatophytes, as they are technically termed---are plants that reproduce via seeds from either flowers or ovules. Seed plants can be subdivided into five major plant types, including flowering plants and conifers.While there are millions of types of seed plants throughout the world, all seed plants share three main characteristics---vascular tissue, seed reproduction and common plant body parts---across all subgroups.eed plants---or spermatophytes, as they are technically termed---are plants that reproduce via seeds from either flowers or ovules.
