Question
- Which of the following statements is NOT acceptable? Phloem unloading may:A. involve the conversion of sucrose to glucose and fructose during apoplastic transport.B. move sucrose through the plasmodesmata to sink cells in symplastic transport.C. more frequently involve apoplastic transport in root sinks and symplastic transport in fruit sinks.D. be inhibited by the endodermis which will prevent the lateral transport of photosynthates.E. involve the transport of photosynthates from sieve elements into parenchyma cells.
Solution
The statement that is NOT acceptable is:
D. be inhibited by the endodermis which will prevent the lateral transport of photosynthates.
Explanation: The endodermis is a tissue in plants that helps regulate the movement of water, ions and hormones into and out of the vascular tissues (xylem and phloem). However, it does not inhibit the lateral transport of photosynthates. Photosynthates, the products of photosynthesis, are primarily transported through the phloem, not the endodermis. The endodermis is more involved in the selective uptake of minerals and water into the xylem.
