Friday Whatsit for November 12, 2010
This week’s image is of something we don’t usually see, but encounter quite often in daily life. They are present in foods and drinks, and we even harbor them on our own bodies.
These little avocado-shaped things (and yes, they are living things) are magnified 1000 x times and still seem small to most biologists. That’s because they are smaller than a plant or animal cell, but bigger than a bacterium or virus.
So if they are not animals, plants, bacteria or viruses, what are they? Whip out ye olde knowledge of the five kingdoms of life and take a guess in the comments section. The answer will be posted on Monday!
