Good question, Cara. There are many places different plants store their food. One way of knowing where a plant stores food is by looking at what parts of the plant animals (like you and I) like to eat. Some plants store food in their roots. Can you think of some plant roots that you've eaten recently? One good example of a root holding lots of plant food is the carrot. Often plants will store food very close to their seeds, this food storage is called a fruit. A fruit is a form of plant food storage that serves two purposes for the plant. It attracts animals to eat the fruit and spread the seeds contained in the fruit. The fruit also provides a source of food for the growing seeds. Some kinds of plants also store water. The cactus lives in deserts where there isn't very much water. Water is usually stored in stems and not leaves, so the plant can protect the water from evaporating in the dry, hot desert environment. I hope this helps!
