Would you expect to find more stomata in a desert cactus or a water lily?

You would expect to find more stomata in a water lily than in a desert cactus. Water lilies grow in aquatic environments where water is abundant, allowing for increased gas exchange through numerous stomata on their surfaces. In contrast, desert cacti have adapted to arid conditions by reducing the number of stomata to minimize water loss, often opening them only at night to conserve moisture.
