Dinoflagellate

A dinoflagellate is a single-celled eukaryotic organism, classified as protists, that are a major component of marine and freshwater plankton. Many species possess two flagella used for movement and exhibit a characteristic shape often reinforced by cellulose plates. They play a crucial role in aquatic ecosystems as primary producers, forming the base of food webs. Some dinoflagellates are bioluminescent, while others are responsible for harmful algal blooms, commonly known as red tides, producing toxins that can harm marine life and humans. Their diverse nutritional strategies include photosynthesis, heterotrophy, and mixotrophy.

Dinoflagellate meaning with examples

• During the summer months, a massive bloom of dinoflagellates turned the coastal waters a vibrant red, leading to concerns about shellfish contamination and potential respiratory issues for beachgoers.
• The research team used advanced microscopy techniques to study the intricate structure of the dinoflagellate's cell wall and flagella, hoping to understand their unique adaptations.
• As primary producers, dinoflagellates form the foundation of the marine food web, providing nourishment for a vast array of zooplankton and larger organisms.
• The sudden increase in dinoflagellate populations in the estuary was linked to agricultural runoff, highlighting the impact of human activities on marine ecosystems.
