Question

Strands of phloem tissue run from the tips of the plant's roots to the tips of

its stems and into its leaves. What does this structure enable phloem tissue
to do?
A. Rid the plant of any waste materials, toxins, or diseases
B. Transport sugars and other organic substances throughout the
plant
OC. Form a protective outer layer to prevent water loss
OD. Form stem cells for the continuous repair and growth of the plant

Answer 1

Answer: B. Transport sugars and other organic substances throughout the plant.

Explanation: The phloem tissue is responsible for the transportation of organic molecules such as sugars, amino acids, and hormones from the leaves to other parts of the plant, including the roots and stems. This process is known as translocation, and it is essential for the survival and growth of the plant. The phloem tissue is composed of specialized cells called sieve tubes, which are arranged end-to-end to form long tubes that span the length of the plant. This structure enables the phloem tissue to efficiently transport sugars and other organic substances from where they are produced in the leaves to where they are needed for growth and metabolism in other parts of the plant.

Answer 2

The correct answer is B. Transport sugars and other organic substances throughout the plant.

Phloem is a type of plant tissue that is responsible for transporting sugars, amino acids, and other organic substances from the leaves where they are produced by photosynthesis to other parts of the plant where they are needed for growth and energy. The strands of phloem tissue, called sieve tubes, are long, narrow, and tube-like, and are connected end-to-end to form a continuous network throughout the plant. This enables the phloem tissue to transport these substances from the tips of the plant's roots to the tips of its stems and into its leaves, where they can be used or stored for later use.
