Spirogyra: Structure and Life Functions (1970, silent)

Still tracking down the soundtrack. Shows masses of spirogyra and close-ups of their filament and cellular structure. Observes the nucleus, cytoplasm, chloroplasts, and pyrenoids through a microscope, and measures the cell length and diameter. Examines a spirogyra culture to observe growth and reproduction.
