Aside from morphological changes such as colour changes in senescent plant organs, several other observations are related to this process, including the loss of water from ageing tissues, the leakage of ions, the generation of reactive oxygen species (ROS), an increase in membrane fluidity and lipid peroxidation (Tripathi & Tuteja The main process that involves the rearrangement of subcellular membranes is the sequestration of cargo, which is later delivered to vacuoles where the segregated material becomes degraded (Levine & Klionsky Senescence is also characterised by substantial changes
