Which of these statements corresponds to the features of Euglenoids?

Correct answer: D. Some photosynthetic euglenoids lose their chlorophyll

  • A. Euglenoids have no special evolutionary significance
  • B. Classified in plant kingdom
  • C. Classified in animal kingdom
  • D. Some photosynthetic euglenoids lose their chlorophyll

Explanation

Some characteristic features of Euglenoids are as follows. • Euglenoids (such as Euglena) are unicellular protists commonly found in freshwater. • Instead of the cell wall, a protein-rich cell membrane known as a pellicle is present. • They bear two flagella on the anterior end of the body. • A small light-sensitive eye spot is present. • They contain photosynthetic pigments such as chlorophyll and can thus prepare their own food. However, in the absence of light, they behave similarly to heterotrophs by capturing other small aquatic organisms. • They have both plant and animal-like features, which makes them difficult to classify and hence they are called connecting links between plants and animals.

About Kingdom Protista

Kingdom Protista contains mainly unicellular eukaryotes, although some forms are colonial or multicellular, with varied nutritional and reproductive methods. Questions examine protozoans, algae and examples such as Amoeba, Paramecium and Euglena, while distinguishing protists from prokaryotes, fungi and true plants.
