what actually is spirogyra: a fungi or algea or what?
also what is the effect of acid rain on the cell structure of spirogyra?
Spirogyra is a type of algae.
and here are two experiments on acid rain effects on Spirogyra:
ALGAE, ALGAE, EVERYWHERE!
Sophomores, Harlingen High School, Harlingen
The purpose of the experiment was to determine the affects of acid rain on
the cell structure of Spirogyra. The
Spirogyra was gathered from a local pond. The water was filtered and
equally divided into three fish bowls,
which contained equal amounts of Spirogyra. One fish bowl served as a
control. The second fish bowl
contained 3 cc of sulfuric acid, while the third bowl contained 12 cc of
sulfuric acid. Throughout the three days
of observing the Spirogyra, the control remained healthy. Bowl two showed
signs of deterioration which
progressed over the three days. In bowl three the Spirogyra was completely
destroyed. Since little research has
been conducted on the affects of acid rain in the Valley, this experiment
hopes o create awareness for further

The Effects of Acid Rain on Spirogyra
The effects of acid-rain on Spirogyra were tested. Three separate
one-gallon fishbowls, each containing an an equal amount of Spirogyra, were
set up. Each day, two drops of 10%
sulfuric acid solution were added to one boal, and one drop to
another. The third boal served as a control. Samples were taken from each
to determine the percentage of the
Spirogyra that survived the acid exposure. The data were analyzed by
