I've noticed that not all plant cells are the same. Some plant cells, such as onion cells, have that rigid shape that you see in text books; but some other plant cells such as duckweed cells have a more rounded shape.
Here are a couple of views of onion cells:
For contrast, here are cells from a duckweed leaf:
The duckweed cell walls are thick, but they aren't rectangles, like the cell walls of the onion cells.
I got a Celestron 44302 digital miscroscope for Christmas. It works pretty well, too, although we've only got it connected to Apple Photo Booth so far, and so the pictures are only 640 X 480 pixels until we get that fixed. Photo Booth has lots of special effects which I worked with on some of the pictures.
I am looking forward to taking more pictures once we figure out how to get the 1.3 megapixel pictures we are supposed to be able to get with this microscope.
One megapixel is 1,000,000 pixels. And 640 X 480 pixels = 307,200. 1.3 megapixels is 1,300,000 pixels. And so, to find out hom much bigger the pictures are that we are supposed to be able to get, we divide 1,300,000 by 307,200, and we get about 4 1/4. And so the pictures we should be able to get are 4 1/4 times bigger than what we are getting now!
The reason we are having a problem is that the computer isn't recognizing the microscope except when we use Photo Booth to get at it. It comes with software for Windows, but is suppsed to work right out of the box with Macintosh, which it doesn't.
This is a picture of a dime, but the letters are backwards because of the lenses in the microscope.
This is one of the traps on a Venus Fly Trap without any special effects. (Also, no special effects were applied to the dime.)
The Warhol effect used on the stem end of the Venus Fly Trap.
This is a picture of a flea stuck to a piece of tape using Photo Booth's x-ray effect.
Here are George Washington's eyes on the dollar bill, using Photo booth's x-ray effect.
