The scientific study of algae is known as:

Phycology is the branch of botany that deals with the scientific study of algae. Algae are simple, photosynthetic organisms that can range from microscopic single-celled forms to large multicellular seaweeds, such as kelp. They are primarily found in aquatic environments, both freshwater and marine, and play a crucial role in ecosystems as primary producers, generating oxygen and forming the base of the food chain.

The study of algae includes understanding their classification, structure, reproduction, ecology, and economic importance. Phycologists examine algae for various purposes: studying their role in oxygen production, biofuel research, water purification, and as food sources in human diets (for example, edible seaweeds). Algae are also important indicators of water quality and are used in research on environmental changes.

Other options are unrelated to algae:

• 
  

  Pomology is the study of fruits and fruit-bearing plants.

  
  


• 
  

  Oneriology is the scientific study of dreams.

  
  


• 
  

  Trichology is the study of hair and scalp.

  
  

Algae exhibit a variety of life cycles, including haploid-dominant, diploid-dominant, and alternation of generations, which makes them an important group for studying evolution and plant biology. Economically, algae are used in pharmaceuticals, cosmetics, fertilizers, and as sources of agar, alginates, and carrageenan.

Understanding phycology is essential in biology, environmental science, and everyday science education, as it helps students appreciate the ecological importance of algae, their industrial applications, and their role in maintaining life on Earth.

In summary, the scientific study of algae is called phycology, a branch of botany that explores their structure, function, reproduction, ecological significance, and practical uses.
