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.
1 Multicellular plant embryos develop from zygotes that are retained within tissues of the female parent. 2  The multicellular, dependent embryo of land plants is such a significant derived trait that land plants are also known as embryophytes. 3  The parent provides nutrients, such as sugars and amino acids, to the embryo.oncept 29.1 Land plants evolved from green algae. 1  Researchers have identified a lineage of green algae called charophyceans as the closest relatives of land plants. 2  Many key characteristics of land plants also appear in a variety of algal clades.
