The reason plants survive in rain forests, the arctic, and deserts is because they have adapted to their environments. Cactus plants have a thick, waxy coating to help prevent water loss. This plant’s stomata open during nighttime, when it’s cooler. Moisture is stored in the center of the cactus plant. Carnivorous plants obtain some nutrients by trapping and digesting insects. When there is more daylight than darkness, long-day plants bloom. This flowering response is known as photoperiodism.
