IPA: /pəˈrɛŋkɪˌmætəs/
KK: /pəˈrɛŋkɪˌmætəs/
Relating to the functional tissue of an organ, especially in plants and animals, that is responsible for carrying out specific functions.
The parenchymatous cells in the plant are essential for photosynthesis and storage.
Parenchymatous → It is formed from "parenchyma" (from Greek "parenchyma", meaning something poured in beside) and the suffix "-tous" (meaning characterized by). The word describes tissue that is characterized by the functional parts of an organ, as opposed to the supportive or connective tissues.
Think of 'parenchyma' as the 'functional tissue' of an organ, and '-tous' means characterized by, so parenchymatous refers to tissue characterized by its functional role.
