T/F question The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules.

Most plants transport sucrose over long distances through the xylem. True or False

QUėstion 24 is based on the following passage. A plant stem's two main functions are to support the leaves and to transport materials between roots and leaves. As a stem develops, it possesses three types of permanent tissues: surface tissue, ground tissue, and vascular tissue. The surface and ground tissues support and give structure to the plant. The vascular tissues are the transport systems of the plant. The vascular tissues usually exist in one of three patterns and are known as the phloem and xylem. Both the xylem and phloem are made up of several different types of cells that make up transport tubes for needed nutrients. In general, xylem nutrients (sap) travel from the roots to the rest of the plant. Phloem sap is derived from photosynthesizing leaves and from there is carried throughout the plant. 24. What would we be able to study by Hg injecting a nutrient dye into the root of a plant? A. phloem sap transport B. all vascular tissues C. xylem sap transport D. pith and cortex…
