Plant
Identification -- Algae |
| The algae are primitive
plants closely related to the fungi. They exhibit no true
leaves, stems or root systems and reproduce by means of
spores, cell division or fragmentation. Some 17,400
species of algae have been identified and thousands more
probably exist. |
|
|
| These organisms have adapted
to many different habitats and exhibit a wide range of
characteristics. They can be found in many places from
hot springs to glaciers, fresh water to salt water and
sandy beaches to rice paddies. |
| On the following pages
nuisance algal growths are classified into 3 general
categories: planktonic, filamentous, and attached-erect
forms. The use of copper sulfate has not been
recommended as research and field usage have shown a
high potential for detrimental environmental effects. In
certain waters copper sulfate is quite toxic to fish and
other organisms. Overuse of this product is common due
to its short-term effectiveness. This can result in
copper build-up in the sediments leading to a sterile
bottom. |
