Why does Algae and Chlorophyll matters?

Algae are organisms very similar to terrestrial plants in some aspects. They provide oxygen to aquatic ecosystems and serve as a food resource for zooplankton species.

Another important characteristic of algae is their ability to respond quickly to changing environmental conditions in the water. This is because different types and species of algae have different requirements for chemical and physical factors in their environment.

Therefore, depending on whether environmental factors are favorable, algae can rapidly increase their population or change the composition of the algal community—an occurrence known as ecological succession.

There is still systematic debate about whether algae belong to Cyanophyta or Protozoa. Some algae are considered protozoa because of certain reproductive and morphological characteristics.

Despite these characteristics, their most important feature is the presence of photosynthetic pigments—chlorophylls, carotenoids, and others. Thanks to these pigments, they carry out autotrophic nutrition known as photosynthesis. During photosynthesis, algae accumulate organic matter. The most abundant type of chlorophyll is chlorophyll a, which is present in all algae.
