Gametophyte Essays

photosynthetic and is separated from the gametophyte. The haploid spores are produced in a sporangium. Each spore divides mitotically to produce a heart-shaped gametophyte. Male and female parts are developed on the same plant. Gametophyte is small in size and can photosynthesize. In order for the fertilization to take place, enough water should be available so that the sperm may swim to archegonia and fertilize the eggs. The sporophyte has vascular tissue and roots; the gametophyte does not. 9) Gymnosperms: a)

Rebecca Dwyer 215 033 159 “The Advantages of a Dominant Sporophyte over a Dominant Gametophyte” It is commonly known by most people that the planet that humans call home is inhabited by many other diverse forms of life. Further than this, it is evident that a large percentage of these life forms are plants. This could be seen as a slight paradox- plants can be considered more primitive than animals, because they are incapable of movement in order to escape from predation, or to reach close contact

Lacey Bassler 1. Functional groups are responsible for the specific characteristics of chemical reactions for the molecules they are attached to. Functional groups are linked to each other and the molecule by covalent bonds. A hydroxyl group is polar due to the high electronegativity of oxygen and it forms hydrogen bonds with water which helps dissolve compounds. A carboxyl group acts as an acid because of the high polarity between the covalent bond of oxygen and hydrogen. An amino group acts

Pg.284 What are examples of unicellular, filamentous, and colonial green algae? An example of filamentous green algae is the spirogyra. An example of unicellular green algae is the chlymodomonas and the colonial green algae example is volvox. How are green algae different from cyanobacteria? ` Cyanobacteria are photosynthetic bacteria while green algae are photosynthetic eukaryotes. Cyanobacteria do not have a nucleus or mitochondria while green algae do. They reproduce asexually while green

of a kelp. Life cycle of kelp can differ between perennial kelp and annual kelp. Yet both types of kelp live a two-stage life cycle. Their haploid phase begins when mature organisms release spores and then germinate to become male or female gametophytes. Their sexual reproduction then results in the diploid sporophyte stage, in which the male sperm and the female egg have fertilized. After the kelp has matures, it will then release spores and the life cycle begins again. 2.b. Why are otters
