Biological classification

Correct option is C.

Euglena is a eukaryotic, unicellular organism, it contains major organelles found in a more complex life. Cytostome or cell mouth is a part of cell specialized for phagocytosis, usually in the form of a groove. Food is directed into the cytostome. Stigma is the light-sensitive part of euglena which appears as a fine spot and helps the euglena to move towards the light. Paramylum is stored in rod-like bodies throughout the cytoplasm called paramylum bodies which are often visible as colorless particles in light microscopy. Their shape is often characteristic of euglena species that produce them. The euglena is unique because it is both heterotrophic and autotrophic. Chloroplasts within euglena trap sunlight which is used for photosynthesis and can be seen as several rod-like structures throughout the cell. So, the correct answer is 'A- Cytostome, B- Stigma, C- Paramylum bodies, D- Chloroplast
