aer·en·chy·ma

 (âr-ĕng′kə-mə)
n.
A spongy tissue with large intercellular air spaces that is found in aquatic plants. It provides buoyancy and allows the circulation of gases.

[New Latin : aer(o)- + Greek enkhuma, filling (from enkhein, to pour in : en-, in; see en-2 + khein, to pour; see chyme).]

aerenchyma

(ɛəˈrɛŋkɪmə)
