  cells_-_the_units_of_life Use My Studiyo to create your own quiz to revise one of the following concepts: Types of cells (prokaryotic, eukaryotic, plant, animal, bacterial) Mitosis Structure and function of cells Biomacromolecules Photosynthesis and respiration Transport across membranes Make sure you have at least ten questions.

Image Source  No, it’s not a stawberry cocktail! Did you know that you can extract DNA using simple kitchen equipment and readily available materials? The CSIRO has some great biology experiments, including this one to extract DNA from onions. You could also use kiwi fruit, dried peas, banana, liver or strawberries. You can see the [...]

Photo Source This week we are starting Chapter 4: Cell Division. On Friday we watched a Clickview video showing the process of cytokinesis and mitosis, which included a discussion with a cancer surgeon about the types of treatments (chemotherapy and radiation) used to prevent cells dividing and multiplying, as they do in tumours. All living organisms [...]

They are both made with yeast (Saccharomyces cerevisiae) - a living organism that produces ethyl alcohol and carbon dioxide when allowed to grow in suitable conditions. This is an example of anaerobic respiration, or fermentation, which produces a small amount of energy (ATP) compared to aerobic respiration. An animation of the process of ATP production during fermentation is [...]

Photo Source If you choose to study microbiology at University, you may be involved with experiments such as this, working in an anaerobic chamber. When you exclude oxygen from the environment, respiration takes place anaerobically – without oxygen. Read more here. Anaerobic respiration is used both in the brewing and baking industries, as alcohol and [...]

Photo Source What’s beetroot got to do with cell biology? Well, today we did a practical experiment to investigate the effect of temperature on the plasma membrane of beetroot tissue. Why beetroot? Because it is relatively easy to identify the amount of damage to cell membranes by observing the pigment leakage from the tissue. We [...]
