Algae are small aquatic plants with simple bodies, but some attain large proportions. All algae are characterized by lacking tissues and organs of organ systems, and have few specialized cells. Half of the world’s oxygen supply comes from these simple plants. These plants do not have true roots, stems, or leaves like the higher plants in phyla, nor do any of them have water-carrying vascular tissue.
I have been observing two algae specimens beginning 2-10- 2010. One algae specimen source is from a cement bird bath and the other specimens source is from a swamp
The below photos where taken 3-20-2010.
