The sensitive plant detects touch through electrical-chemical means, communicating information from cell to cell. Plant cells change shape by adjusting water content, leading to swelling or shrinking and, consequently, leaf movement.

The directional movement of a seedling, such as the root going down and the stem coming up, is a result of growth. If growth is prevented, the seedling will not display the expected movement.

The movement of a sensitive plant’s leaves is rapid and independent of growth, whereas the directional movement of a seedling is attributed to growth; if growth is hindered, the seedling will not exhibit movement.

Plants, such as the sensitive plant, respond to touch through rapid movements of their leaves, a process not involving muscle action, but rather a quick response mechanism.

Different areas of association in the fore-brain interpret sensory information by combining inputs from various receptors and stored information, ultimately leading to the formation of decisions and responses.
