Red algae

Red algae (Rhodophyta, red algae) are one of the most interesting and mysterious groups of algae. They have red pigments that give them their characteristic hue, which is why they are often called red algae. However, these algae are not always red. Some species may have green, blue or yellow pigments.

Red algae belong to the phylum Rhodophyta and are one of the most common members of algae. Red algae are complex organisms that consist of one or more cells covered with a kind of membrane - cellulose (sometimes they are also called simple plants, since they do not have roots, stems and leaves). Their cells contain red, yellow or orange chromogen pigments. When algae cells die, they fall to the bottom of lakes, seas and rivers, where they form special thalli (“twig-like”, perennial), sometimes forming huge thickets. Red algae is a food source for many marine animals such as fish and seabirds. In addition, they are used as additives in food and medicine. For example, the red pigment astaxanthin, which is found in red algae, is used in cosmetics to produce anti-wrinkle creams and lotions. Algae are an important part of the ecological system of seas and oceans. They help regulate the amount of oxygen and carbon dioxide, and also purify water from contaminants and harmful substances. Red algae also plays an important role in human life. They are used in food, cosmetic products and medicines.
