IPA: /ˌhɛtəˈrɒfɪli/
KK: /hɛtəˈrɒfɪli/
The occurrence of different leaf shapes on the same plant, often due to changes in the environment.
Heterophylly allows a single plant to adapt its leaves to varying conditions, such as light and water availability.
Heterophylly is formed from "hetero-" (from Greek "heteros", meaning different) and "phyllon" (from Greek, meaning leaf). The term describes the condition of having different types of leaves on the same plant.
Think of 'different' ('hetero-') leaves ('phyllon') on a plant — that's what heterophylly means.
