ô mắt

Một con ruồi có hàng trăm ô mắt trong mắt kép của nó.

Definition

1. Noun:
   • Ommatidium: A single, small optical unit that makes up the compound eye of an arthropod (e.g., an insect or crustacean). Each ommatidium functions as a separate photoreceptor, contributing a small part of the overall image.
   • Facet: In common, non-technical language, "ô mắt" can refer to one of the many small, hexagonal surface units that form the compound eye, resembling a tiny window or compartment.

Usage Examples

• Noun:
  • Mỗi ô mắt trong mắt kép của con ong nhận một phần hình ảnh. (Each ommatidium in the bee's compound eye receives a part of the image.)
  • Dưới kính hiển vi, chúng ta có thể thấy rõ từng ô mắt. (Under the microscope, we can see each facet clearly.)

Advanced Usage

• This term is primarily used in biological and zoological contexts. In everyday conversation, it is not commonly used unless discussing insect anatomy.

Variants and Related Words

• Mắt kép (n): Compound eye. The entire visual organ composed of many ommatidia.
  • Côn trùng có mắt kép. (Insects have compound eyes.)

Synonyms

• Ommatidium: The precise scientific term.
• Facet: A more general term for one of the small surfaces on a compound eye.

Notes

• "Ô mắt" is a technical term. The word "ô" here means a compartment or a cell (like in a grid), and "mắt" means eye. It literally translates to "eye compartment" or "eye cell."
