1. What are Algae? Describe their general
characteristics.
Algae are predominantly aquatic, photosynthetic organisms that may be unicellular,
colonial, or multicellular.
• Mostly photoautotrophic and contain chlorophyll and other pigments.
• Found in freshwater, marine water, ponds, streams, and damp soil.
• Range from microscopic unicellular forms to large seaweeds.
• Eukaryotic cell organization with nucleus and chloroplast.
• Reproduce by vegetative, asexual, and sexual methods.
• Important in ecology, oxygen production, and food chains.
, 2. Describe the structure and organization of algal
cell.
• Cell wall provides protection and shape.
• Plasma membrane and cytoplasm with mitochondria and ER.
• Chloroplast contains pigments and stores starch.
• Nucleus is membrane-bound and well organized.
• Vacuoles help in storage and osmoregulation.
• Some algae possess flagella for motility.
