AP BIOLOGY

Detailed explanation-1: -Plant adaptations Their leaves and flowers grow in the canopy. Tree trunks-these are tall and thin to allow trees to reach the sunlight. The bark on these trees is smooth to allow water to flow down to the roots easily.

Detailed explanation-2: -But large leaves can cope in hot, wet, tropical climates because they counteract the daytime heat-trapping effect using transpiration – something desert plants cannot do because they cannot afford to lose that much water.

Detailed explanation-3: -Many rainforest plant leaves have waxy surfaces and “drip tips” where each leaf apex is extended or pointed. These features quickly shed excess water so that the process of photosynthesis is not affected and fungal growth is reduced.

Detailed explanation-4: -Although tropical rainforests receive 12 hours of sunlight daily, less than 2% of that sunlight ever reaches the ground. The tropical rainforest has dense vegetation, often forming three different layers–the canopy, the understory, and the ground layer.
