Paramecium bursaria with music by @andrewkeoghan. . P. bursaria is a single cellular organism, a ciliate with a resident population of green algae called Chlorella. All those little green dots are living algae cells. The algae and the ciliate live together and share resources. The ciliate provides a nice mobile home for the algae, and in return the algae make sugars that they share with the ciliate. . The ciliate still eats, you can see it trap and swallow a small colony of a different algae it the first part of this clip. This is one of the ways that the Chlorella algae can get inside the ciliate, by getting eaten! The Chlorella don’t get digested, though. It’s thought that the Chlorella interfere with the ciliate’s digestion, altering the digestive vacuoles that they are contained in so that they sustain the algae, rather than devour them.
These are desmids, single cellular green algae with pleasing symmetry. The sparkling is the movement of tiny molecules and particles and vesicles inside each cell. This movement is known as Brownian motion, a phenomenon that causes small things to move constantly and randomly when in liquid. This is because the molecules that form the liquid, like water molecules, are constantly moving and bumping into the small, visible particles, causing them to move too. Music by @andrewkeoghan 🎼💛
Next Saturday April 28th I’m running a workshop as part of @under_story, in collaboration with the New York Microscopical Society. If you buy a ticket to my workshop it includes entry to the whole @under_story event! More details and links to where you can buy a ticket in my highlights. . We will have microscopes and microorganisms from all over the city for participants to look at. We’ll learn about microorganisms and microscopy! . I’m really excited to be there with a ton of other great people and organizations from all over the city including @newtowncreek, @Publiclab, @girlsclubny, @tulahouse and many more! . More details and links to where you can buy a ticket in my highlights.
A photomontage of green algal colonies from at least three species growing on agar. Photographed at 100 x magnification. Swipe for detailed images. 💚
Wee gonium at higher magnification. Most of the colonies here are four cell units. But, nature is not perfect and you can see many colonies here that are only two celled, and many more that are simply individual cells. It doesn’t matter to gonium. Each cell is perfectly capable of living and reproducing alone or in a group.
