ALGAE Prepared by: Mellprie B. Marin, PhD DESCRIPTION Plant-likeorganisms that are usually photosynthetic and aquatic Have chlorophyll: can manufacture own food Eukaryotes DESCRIPTION Donot have true roots, stems, leaves, vascular tissue, and have simple reproductive structures Distributed worldwide: in the sea, in freshwater and in moist land Mostare microscopic, but some are large (ex. marine seaweeds that can exceed 50m in length) SIGNIFICANCE OF ALGAE Important in aquatic food chain Indicator for water pollution Indicator/ source of petroleum deposit Source of energy and food for man Causal agent of plant disease has the misleading common name “red rust” appear as fuzzy, bright orange spots on leaves and stems and look like rust fungi ALGAL SPOT DESCRIPTION Cephaleuros virescens – occasionally mistaken as fungi MANAGEMENT Proper plant spacing and pruning to increase air circulation and light Sanitation Appropriate fertilization and irrigation
