What are cactus plants and evergreen trees designed to do?

Cactus plants and evergreen trees are designed to thrive in their specific environments by adapting to their surroundings. Cacti have evolved to store water and minimize moisture loss, allowing them to survive in arid conditions. Evergreen trees, on the other hand, are adapted to retain their foliage year-round, enabling them to photosynthesize continuously and endure varying weather conditions. Both types of plants contribute to their ecosystems by providing shelter and resources for wildlife.
