Euglenoids: Structure & Nutrition — NEET Biology
📚 Practice ConceptMajority of them are fresh water organisms found in stagnant water. Instead of a cell wall, they have a protein rich layer called pellicle which makes their body flexible. They have two flagella, a short and a long one. Though they are photosynthetic in the presence of sunlight, when deprived of sunlight they behave like heterotrophs by predating on other smaller organisms. Interestingly, the pigments of euglenoids are identical to those present in higher plants. Example: Euglena.
Which of the following statements correctly highlight the key differences between Euglenoids or Protists in general, and true plants (Kingdom Plantae)? S1: Euglenoids possess a flexible protein-rich pellicle instead of a rigid cell wall, whereas plant cells have a cell wall primarily made of cellulose. S2: While both Euglenoids and true plants are capable of photosynthesis, Euglenoids distinctively exhibit heterotrophic nutrition when deprived of sunlight, a feature generally absent in most plants. S3: The photosynthetic pigments in Euglenoids are structurally distinct from those found in higher plants, allowing for different light absorption capabilities. S4: All organisms under Kingdom Plantae are exclusively autotrophic, contrasting sharply with the diverse nutritional modes observed across Protista. S5: Kingdom Protista is characterized by unicellular eukaryotic organisms, fundamentally differing from Kingdom Plantae, which comprises multicellular eukaryotes.
