Answer:

• Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. Algae are usually green, but they can be found in a variety of different colours. For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue.
• Characters of Algae are as follows
• Algae are photosynthetic organisms
• Algae can be either unicellular or multicellular organisms
• Algae lack a well-defined body, so, structures like roots, stems or leaves are absent
• Algaes are found where there is adequate moisture.

• Algae are free-living, although some can form a symbiotic relationship with other organisms.
