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.
Inaddition, seed plants produce much of the oxygen you breathe. Seed plants share two important characteristics. Theyhave vascular tissue, and they use pollen and seeds to repro-duce. In addition, all seed plants have body plans that includeroots, stems, and leaves.Like seedless plants, seed plants havecomplex life cycles that include the sporophyte and the game-tophyte stages.In seed plants, the plants that you see are thesporophytes.ketches should include the seed coat, the cotyledons, and the embryo.Extend Invite students to repeat the activity with other kinds of seeds. learning modality: kinesthetic How Seeds Become New Plants All seeds share important similarities. Inside a seed is a partiallydeveloped plant.
