    The document is a 10 question multiple choice test about transport in plants. It tests knowledge about how water and carbohydrates move through plant tissues, specifically that xylem transports water upwards and phloem transports sucrose between plant parts. It also covers the processes of transpiration, where water is lost from leaves, and how water and carbohydrates move through the xylem and phloem.

    S 6 Which statements about xylem and phloem are correct?
    A Xylem transports water from roots to leaves, and phloem
    transports sucrose from regions of production to regions
    of storage.
    B Xylem transports sucrose from leaves to roots, and phloem
    transports water from roots to leaves.
    C Xylem transports starch from leaves to roots, and phloem
    transports sucrose from regions of storage to regions of
    photosynthesis.
    D Xylem transports water from leaves to roots, and phloem
    transports starch from roots to leaves.

    7 What causes water to move up xylem vessels in a plant stem?


    A The root hair cells use energy to move water into the roots.
    B Transpiration reduces the pressure at the top of the
    xylem vessels.
    C The water moves up the xylem vessels by osmosis.
    D Water is pushed up the xylem vessels by active transport.

    8 How does water travel up xylem vessels?


    A by osmosis
    B by evaporation from cell surfaces
    C flowing in a continuous column
    D moving by active transport

    9 Which carbohydrate is transported in phloem?


    A amino acids
    B glucose
    C starch
    D sucrose

    10 Potato plants start to grow from old stem tubers in spring.


    What is a source and what is a sink at this stage of the life cycle?
    A Leaves are a source and roots are a sink.
    B Stem tubers are a source and new shoots are a sink.
    C Flowers are a sink and roots are a source.
    D Leaves are a source and stem tubers are a sink.
