Word of the Week Wednesday

Hello my raviolis.  Today is word of the week Wednesday and today's word comes from Owen's spelling bee.  This is one of the words he had to spell (and he spelled it correctly) and it is a favorite word of grandma-ma's.  That word is

"paramecium"

What is a paramecium you ask.  Well, a paramecium is a small, one celled (unicellular) living organism that can move, digest food, and reproduce. They belong to the kingdom of Protista, which is a group (family) of similar living micro-organisms.  Micro-organism means they are a very small living cell. I like them because they look like little footprints in sand.  A paramecium is an oval, slipper shaped micro-organism, rounded at the front/top and pointed at the back/bottom.  Covering the outside of the organism are many tiny hairs, called cilia.



Here is a video of a paramecium eating yeast (the yeast has been dyed red so you can see how this little once celled animal stuffs itself with the food).  Look how quickly it moves.

This may be a difficult word to use in three sentences, but let's give it a go anyway.  Here is grandma-ma's first sentence:

The paramecium moves very quickly with the aid of the tiny hairs around the animal.

Have a wonderful day my loves.  Grandma-ma
