Chloroplast movement in Elodea 11/11/2018

Elodea is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. Elodea is native to North and South America and is also widely used as aquarium vegetation. It lives in fresh water (Wikipedia). Chloroplasts can move in all plants but are particularly visible in Elodea.

I used my Leitz Laborlux 11 microscope today to view a thin slice of Elodea leaf  with a bright light from the side to stimulate movement.

In the next photo, look carefully – there are many tiny organelles visible apart from the more obvious chloroplasts:
