What are storage leaves primarily modified for?

Storage leaves are primarily modified for water storage, which is why this answer is correct. In many plants, particularly succulents, storage leaves serve a critical function in conserving water during dry periods. These modified leaves often have thick, fleshy structures that allow them to store and retain moisture, thereby supporting the plant's survival in arid environments.

Other choices, such as insect attraction, light absorption, or seed dispersal, represent different adaptations that plants may use but are not the primary function of storage leaves. Insect attraction generally relates to features in flowers or colorful structures designed to draw pollinators, while light absorption typically involves broad, flat leaves that maximize photosynthesis. Seed dispersal mechanisms involve fruits and specific structures related to reproductive strategies, not the modification of leaves for storage purposes.
