Last weekend I found some Euglene spirogyra in a puddle. One specimen was so kind to lay still and flat for a photoshooting. On the left image you can see the nucleus a little to the left of the middle of the cell, two big and many small paramylon grains, many chloroplast, the red eyespot, and on top, a little out of focus, the flagella. The right image is focused on the warts on the pellicula.
