With respect to transport within vascular plants Group of answer choicesSucrose is transported in the phloemRequires energy from respiration for movement of waterOccurs in one direction onlyOccurs only in dead cells
Solution
The transport within vascular plants involves two main types of tissues: xylem and phloem.
-
Sucrose is transported in the phloem: This is true. The phloem tissue is responsible for the transport of organic nutrients, particularly sucrose, which is a type of sugar. This process is known as translocation.
-
Requires energy from respiration for movement of water: This is partially true. The movement of water through xylem tissue does not directly require energy as it occurs through a process known as capillary action. However, the overall process of water absorption and transport can be indirectly linked to respiration as the plant's metabolic processes (including respiration) contribute to the creation of a water potential gradient.
-
Occurs in one direction only: This is false. While the xylem transports water and nutrients from the roots to the rest of the plant (unidirectional), the phloem can transport sucrose and other organic compounds in multiple directions (bidirectional), from sources (where they are produced, such as leaves) to sinks (where they are needed, such as roots and fruits).
-
Occurs only in dead cells: This is partially true. The xylem tissue consists of dead cells and is responsible for the transport of water and minerals. However, the phloem tissue consists of living cells and is responsible for the transport of organic nutrients like sucrose.
