A mutation disrupts the transportation system in a plant, causing accumulation of oxygen and waste products in leaf cells. Which two life processes are most directly hindered as a result?
Respiration and excretion
The transport system (xylem and phloem) carries gases and waste products through the plant. If oxygen and wastes accumulate in leaf cells instead of being used or removed, it directly shows that gas exchange (respiration) and removal of metabolic waste (excretion) are impaired.
Hence, the two life processes most directly hindered are respiration and excretion.
