Characteristics of Cyanobacteria
Cyanobacteria are a group of photosynthetic bacteria that are found in diverse habitats. They have the following characteristics:
Formation of Colonies
Cyanobacteria can form colonies that can range in size from a few cells to massive structures that can be seen from space. These colonies can take various shapes, including filaments, sheets, and spheres.
Nitrogen Fixation
Cyanobacteria are capable of fixing atmospheric nitrogen, making it available to other organisms. This is important because nitrogen is an essential nutrient for plant growth, and is often a limiting factor in many ecosystems.
Blooms in Polluted Water
Cyanobacteria can form blooms in polluted water. These blooms are often toxic and can cause harm to humans and animals that come into contact with them. They can also cause problems for aquatic ecosystems by reducing oxygen levels and blocking sunlight.
Explanation
The correct answer is option 'C' - Cyanobacteria are not multicellular. Although some cyanobacteria can form colonies, they are not truly multicellular organisms. Unlike multicellular organisms, which have specialized cells that perform different functions, individual cyanobacteria cells are capable of carrying out all necessary functions on their own. Therefore, cyanobacteria are considered to be unicellular organisms, even when they form colonies.
