Elodea densa (AKA Egeria densa) is an aquatic flowering monocot plant from South America that is used in biology classes to show the structure of plant cells. Inside the plant cell, the rigid cell wall is visible along with the chloroplast that move with the cytoplasmic stream of the cell. Placing an Elodea leaf in a 10% Sodium Chloride solution (100 g/L) will cause the cell to lose water through osmosis (plasmolysis), but the cell wall will keep the rectangular cell shape even as the plasma membrane shrinks. The last frames include what the Elodea leaf looks like with Methylene blue stain. • It is interesting to note how similar the chloroplasts look like to unicellular algae, which supports the endosymbiotic theory of eukaryotic cells. https://en.wikipedia.org/wiki/Symbiog... • • The Magnification of each shot is included in the bottom right corner. • Music: / cytoplasmic-stream-elodea-densa-egeria-densa
