Cactus stems get bigger for two main reasons. One reason is normal growth. The other is an increase in the amounts of stored water, nutrient solutions, and energizing photosynthetic products. This last reason is why a cactus is ribbed. Its ribbing allows the cactus to decrease its size when it has lesser amounts in storage, and to increase with greater amounts.
