The phloem parenchyma is a type of plant tissue that plays a role in food storage. Specifically, it stores carbohydrates (such as sugars) that are produced during photosynthesis in the leaves. These stored carbohydrates can then be transported to other parts of the plant that need them for energy or growth. The phloem parenchyma does not support the stem or produce the sieve tube, and it is not involved in transporting water.
