How are pine and catus leaves different?

Pine leaves, or needles, are typically long, slender, and evergreen, allowing them to retain moisture and endure cold climates. In contrast, cactus leaves are often reduced to spines or are absent entirely, with the plant using a thick, fleshy stem for photosynthesis and water storage. This adaptation helps cacti survive in arid environments by minimizing water loss. Overall, the structural features of both types of leaves reflect their respective adaptations to their environments.
