Bruce Rogers asked:
Do bacteria sleep or have a pattern to their activity?
We put this question to Dr Harriet McWatters:
Ordinary bacteria such as you would find in your gut probably not. There is a class of blue-green algae which are often called cyanobacteria which have very strong circadian rhythms.
therodgers21 asked the Naked Scientists: Hi, Iím a new fan of your show. I live in Silicon Valley (it sounds far more noble than Milpitas, no?). I find your show to be the best way to demystify science. You offer a simple enough introduction to make the subjectís specifics understandable. Listening to a bright lady with a sexy voice doesnít hurt either. My question: do all living things require rest? Case in point: do bacteria sleep or have a pattern to their activity? Thanks, Bruce Rodgers --------------------------------- What do you think? therodgers21 , Wed, 4th Jun 2008
Photosynthetic bacteria are governed by sunlight exposure, so would behave differently in the day and in the night.
