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.
The nonvascular plants -- bryophytes -- require a constantly moist environment. They include: seedless vascular plants such as-club mosses horsetails ferns (pterophyta) which are the most numerous of this type of plant seed-bearing forms.lants-Adaptations to Land. Some of the adaptations of plants to a terrestrial existence include a waxy cuticle, surface pores (stomata) that enable gas exchange, protected reproductive structures, and the retention of the embryonic sporophyte within the female gametophyte.
