Exchange, Transport & Reproduction Explored

Exchange, Transport and Reproduction Defined

You'll encounter these topics early on in AS Level Biology / Biology A Level year one. Reproduction and growth occur due to cell division, and cells are transported through the blood system. Exchange processes include movement of blood, water and bodily fluids.

Why Study Exchange, Transport and Reproduction?

These processes are core elements of biology; cell division is central to biological growth and repair. Appreciating the interaction of cells, organs and tissues, including transport and reproduction, is critical to understanding how whole organisms function.

What Will I Study?

In this part of Biology AS or A Level, your coursework will include writing essays on how multicellular organisms require specialised exchange surfaces in order to function. Your practical projects will cover topics including calculating diffusion rates and making serial dilutions.

Further Study after Exchange, Transport and Reproduction

The essays, projects and coursework you undertake will enhance your knowledge of heart, circulatory and respiratory systems. This understanding will enable you to study multicellular systems in further depth during your Biology A Level, and to continue to Degree-level study of Biology.

Recent Reviews of Exchange, Transport & Reproduction Essays

What our users think of the Exchange, Transport & Reproduction essays in this section:

"Well written with extremely good scientific reasoning."
adrian-polglase
"very precise and to the point."
Noradin
"Quite weak. From the start the author fails to demonstrate a a full understanding of why osmosis occurs - for example, using the word 'jump' to describe molecular movement is very imprecise and does not reflect the true explanation. The method then seems fine and the results are clearly tabulated, but a graph would be a useful further illustration of these. Finally, the conclusion and analysis are notably brief, and I would expect to see at least some assessment of how well the experiment went and the quality of the recorded data. TSR User: Illusionary"
