A botanist has two samples of liquid. Sample A is composed primarily of organic materials, while sample B is composed mostly of water and minerals. Which liquid was extracted from the xylem of a plant and which came from the phloem

Sample A: Phloem

Sample B: Xylem

Explanation:

Xylem and phloem are the tissues of vascular plants. These tissues are involved in the transport of substances. Xylem is the tissue of these plants that transport water and dissolved minerals from roots to the other parts of the plant body. Phloem is the tissue that transports sugars and organic materials from source tissues to the sink tissues of plants. Therefore, sample A with organic materials was obtained from phloem while sample B came from xylem.
