NettetSTRUCTURE OF EUGLENA: Plasma membrane: It is a thin, semi-permeable membrane which surrounds the cytoplasm of the cell enclosing the contents. Cytoplasm: It is a jelly-like, watery substance inside the cell. Chloroplasts: These are the plastids that consist of chlorophyll that helps in absorbing light energy for photosynthesis. NettetNutrition in Euglena is of 2 types: Holophytic or Autotrophic Nutrition: Using Chloroplast they produce food from sunlight, water, carbon dioxide, or other chemicals. Saprophytic or Saprozoic Nutrition: Using Pellicle they derive their food from dead and decaying matter. 1. Holophytic or Autotrophic Nutrition.
