Euglenoids exhibit a fascinating mixotrophic nutrition. When deprived of sunlight, how do they obtain energy?

According to NCERT Biology, Euglenoids are remarkably unique because they are photosynthetic autotrophs when sunlight is available. However, they exhibit 'mixotrophic' behavior. When deprived of sunlight, they seamlessly switch their mode of nutrition and behave completely like heterotrophs by actively predating on other smaller microscopic organisms present in their aquatic environment, demonstrating a fascinating evolutionary link.

Instead of a rigid cell wall, Euglenoids possess a protein-rich layer that makes their body highly flexible. What is thi

Euglenoids, a fascinating group of protists found mainly in fresh stagnant water, distinctly lack a rigid cellulosic cell wall. NCERT text states that instead, they are covered by a specialized, tough yet flexible protein-rich layer known as a 'pellicle'. This structural adaptation provides them with substantial physical protection while keeping their body incredibly flexible for varied movements.
