What is a key characteristic of tropical plants?

Tropical plants are characterized by their adaptation to warm and humid environments, which is essential for their growth and survival. This is primarily due to their origin in regions near the equator, where temperatures are consistently warm and the air is often humid. Such conditions promote the processes of photosynthesis and transpiration, allowing tropical plants to flourish.

While many tropical plants can indeed be evergreen, meaning they retain their leaves throughout the year, this characteristic is not exclusive to them as many plants in different climates also exhibit evergreen traits. Additionally, while several tropical plants do benefit from sunlight, saying they "require a lot of sunlight" does not capture the essence of their environmental needs as comprehensively as their preference for warmth and humidity does. Tropical environments are typically associated with lush vegetation and diverse ecosystems due to the ideal conditions they provide.
