Choose the correct answer for the given question from the options:
A researcher blocks all turgor-pressure changes in a Mimosa pudica plant but keeps growth processes normal. What will be observed when the plant is touched, and why?
Seedling-like directional movement will occur instead of leaf folding
Leaves will not fold because nastic movement requires turgor changes, not growth
Leaves will fold slowly because growth-based movements replace turgor movements
Leaves will still fold because growth hormones trigger rapid movement
