The picture above is of a plant's xylem and phloem. The xylem transports water from the roots to the leaves. The phloem transports food from the leaves made by photosynthesis to the rest of the plant. This vascular bundle (xylem and phloem) is similar to a human tissues. Place the xylem and phloem with the human tissues that is most similar to it. The statement is to be read as ":" reads "is to" and "::" reads "as". ex: Kitten: cat :: puppy: dog can be read as "kitten is to cat as puppy is to dog".
