•how are the organs of plants adapted to perform essential functions?<br>​
lions [1.4K]
Every plant organ is adapted to its function. For example, leaves that are big and flat absorb plenty of sunlight for photosynthesis. Long roots keep a tree stable and take water from deep in the soil. Some plants have unusual adaptations.
