Cellular Reproduction

Cellular Reproduction is the process by which all living things produce new organisms similar or identical to themselves. This is essential in that if a species were not able to reproduce, that species would quickly become extinct. Always, reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. (Encarta, 2) In almost all animal organisms, reproduction occurs during or after the period of maximum growth. (Fichter, 16). But in Plants, which continue to grow through out their lifetime, therefore making the process more complex. Plants' reproduction is usually caused by a stimulant, mostly environmental or growth factors. The reproductive process, whether asexual or sexual always involves an exchange in hereditary material from the parent(s) so that the new organism may also be able to reproduce. Reproductive processes can be categorized in many diffrent ways although the most common is to put them into either asexual reproduction or sexual reproduction. Asexual reproduction is the process by which a single organism gives rise to two or more daughter cells. Most single celled organisms reproduce by the asexual process known as fission, which is

Response to the question

Response to the question is very in depth, but the response to the question could be set out in a much clearer way. The conclusion could be expanded a lot more to provide a more rounded view of the main text. The introduction is adequate and sets out the main concepts of basic cellular reproduction well.

Level of analysis

Introduction is good and to a basic level, setting out the concepts of cellular reproduction well. The main body of the text goes into very in depth analysis to a level I would expect from an A level candidate rather than a GCSE one, with scientific concepts explained well. Rather than explaining all the different parts of meiosis, the candidate could analyse the different uses, and relate use to function. Conclusion is adequate but does not bring all the concepts explained into an strong conclusion. Could include diagrams and split up the text a lot more. Use of external sources is good.

Quality of writing

No paragraphs makes the essay very hard to read. Punctuation, grammar and spelling are all accurate and terms used are to a very high scientific level beyond what I would expect for GCSE level.
