Definition

1. Noun:
   • Euglena: A microscopic, single-celled organism belonging to the genus Euglena, commonly found in freshwater. It is a protist that typically possesses chlorophyll and can photosynthesize like a plant, but is also capable of moving and feeding like an animal.

  • Nhãn trùng là một sinh vật đơn bào thú vị. (The euglena is an interesting single-celled organism.)
  • Dưới kính hiển vi, chúng tôi quan sát thấy nhiều nhãn trùng trong mẫu nước. (Under the microscope, we observed many euglena in the water sample.)

Advanced Usage

• The term "nhãn trùng" is a specialized biological term. In less scientific contexts, it may be referred to more generally as a type of microscopic pond life or algae.

Variants and Related Words

• Trùng roi (n): Flagellate. A broader category of single-celled organisms that move using a whip-like structure called a flagellum, which includes euglena.

Notes on Meaning

• The word "nhãn trùng" is a compound noun from "nhãn" (eye) and "trùng" (bug, worm), likely referring to the organism's light-sensitive eyespot. It refers specifically to the euglena and is not a general term for all microscopic organisms.
