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.
Most ferns are small plants that lack woody tissue. In this lab you will investigate the diversity of pterophytes, including whisk fens, horsetails and a variety of ferns. The plants on display are sporophytes, the dominant generation in seedless vascular plants.Procedure: 1. Examine a living whisk fern on display. This is one of only two extant genera of Psilophytes. Observe the spherical structures on the stem.n this lab you will investigate the diversity of pterophytes, including whisk fens, horsetails and a variety of ferns.
