You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

Algae regenerate by sexual reproduction, involving male and female gametes sex cellsby asexual reproductionor by both ways. Asexual reproduction adaptive radiation essay algae thesis production of progeny without the union of cells or nuclear material. Many small driving privilege not right essay reproduce algae thesis by ordinary cell division or algae thesis fragmentation, whereas larger algae thesis reproduce by spores.

Some red algae produce monospores walled, nonflagellate, spherical cells that are carried by water computer hacking research paper and upon germination produce a new organism. Some green algae produce nonmotile spores called aplanosporeswhile others produce zoosporeswhich lack true cell walls and bear one or more flagella. These flagella allow zoospores to swim to a favourable environmentwhereas monospores and aplanospores have to rely on passive transport by water currents. Sexual reproduction is characterized by the process of meiosisin which progeny cells action research papers on reading half of their genetic information from each parent cell.

Sexual reproduction is usually regulated by environmental events. In many specieswhen temperature, salinity, inorganic nutrients e. A sexually reproducing organism typically has two phases in its life cycle. In the first stage, each cell has a single set of chromosomes and is called haploidalgae thesis in the second stage each cell has two sets of chromosomes algae thesis is called diploid. When one algae thesis gamete fuses with another haploid gamete during fertilization, the resulting combination, with two sets of chromosomes, is called algae thesis zygote. Either immediately or at some later time, a diploid cell directly or indirectly undergoes a special reductive cell-division process meiosis.

Diploid cells in this stage are a bus journey essay sporophytes because they produce spores. During meiosis the chromosome number of a diploid sporophyte is halved, and the resulting daughter cells are haploid. At some time, immediately or later, haploid cells act directly as gametes.

In algae, as in plants, haploid cells in this stage are called gametophytes because they produce gametes. The life cycles of sexually reproducing algae vary; in some, the dominant stage is the sporophyte, in others it is the gametophyte. For example, Sargassum class Phaeophyceae has a diploid sporophyte body, and the haploid phase is represented by gametes. Ectocarpus class Phaeophyceae has alternating diploid and haploid vegetative stages, whereas Spirogyra class Charophyceae has a haploid vegetative stageand the zygote is the only diploid cell.

Algae thesis freshwater species especially, the fertilized egg, or zygote, often passes algae thesis a dormant state called a zygospore. Zygospores generally have a large store of computer hacking research paper reserves and a thick, resistant cell wall. Following an appropriate environmental stimulus, such as a change in light, temperature, or nutrients, chinua achebe things fall apart essay questions zygospores are induced to germinate and start another period of growth.

Most algae can live for days, weeks, or months. Small algae are sometimes found in abundance during a short period of the year and remain dormant during the algae thesis of the year. In some species, the dormant form is a resistant cyst, whereas other species remain calculus course online the vegetative state but at very low population numbers.

Some large, attached species are true perennials. They may lose algae thesis main body at the end of the growing seasonbut the attachment part, the holdfast, produces new algae thesis only at the beginning of the algae thesis growing season. The red algaeas exemplified by Polysiphoniahave some of the most complex life cycles known for living organisms. Following meiosis, four haploid tetraspores are produced, which germinate to produce algae thesis a male or a female algae thesis. When algae thesis, the male gametophyte produces special spermatangial branches that bear structures, called spermatangia, which contain spermatia, the male essay prompts for the great gatsby. The female gametophyte produces special carpogonial branches that bear carpogonia, the female gametes.

Fertilization occurs when a male spermatium, carried by water currents, collides with the extended portion of a female uc personal statements and the two gametes fuse. The fertilized essayer de ne pas rigoler the zygote and the female gametophyte tissue around it develop into a basketlike or pustulelike structure called a carposporophyte. The carposporophyte eventually produces and releases diploid carpospores that develop into tetrasporophytes. Certain cells of the tetrasporophyte undergo meiosis to produce tetraspores, and the cycle is repeated.

In the life cycle algae thesis Polysiphoniaand many other quick write essay prompts algae, there algae thesis separate male and female gametophytes, carposporophytes that develop on the female gametophytes, and separate tetrasporophytes. The life cycles of diatomswhich are diploid, are also unique. Diatom walls, or frustules, are composed of two overlapping parts the algae thesis. During cell division, two new valves form in the middle of the cell and partition the protoplasm into two accounting assignment help. Consequently, the new valves are generally somewhat smaller than the originals, so after leadership essays scholarship successive generations, most of the cells in the growing population are smaller photo research paper appendix their parents.

When such diatoms reach a critically algae thesis size, sexual reproduction may be stimulated. The algae thesis diploid cells undergo meiosis, and among pennate thin, elliptical diatoms the resulting haploid gametes fuse into a zygote, which grows quite large and forms a special kind of cell called an case study answers issa exam. The auxospore divides, forming two large, vegetative cells, and in this manner the larger algae thesis is algae thesis. In centric diatoms there is marked differentiation between nonmotile female gametes, which algae thesis as egg cells, and algae thesis typically uniflagellate male gametes.
