Question

Quizplus · Accepted Answer

The presence of stoma on the lower surface of the leaf suggests that this leaf is adapted to a wet and humid environment where there is a lot of moisture available. The dark green color may indicate that it is adapted to low light levels, which are commonly found in the understory of tropical rainforests. Additionally, the large surface area of the leaf suggests that it is adapted to capturing as much light as possible in order to carry out photosynthesis, which is common in the highly competitive tropical rainforest environment.
