Why is Mimosa shy? Under what circumstances does Mimosa become shy?

1. Why are you shy?

Its leaves can close when stimulated by external factors, and then reopen, as if it were shy. The reason why it is shy is because the structure of its leaves can have a "turgor effect". The part connected to the petiole under the leaflet has a relatively special structure. This structure can determine whether the leaf is closed or open, that is, the pulvinus, which is filled with many thin-walled cells and contains some cell sap. When stimulated by external factors, the leaves will vibrate. At this time, the water in the pulvinus will flow to other places, and the lower part of the pulvinus will shrink, causing the petiole to droop and close. When the external stimulus disappears, the water flows back to the pulsatilla, causing it to be filled with water again, and its leaves will open again.

2. What situations will make you shy?

The leaves of Mimosa pudica close mainly due to external stimuli. When people touch the leaves with their fingers, the leaves will vibrate and contract. In addition to being touched by people's hands, when the leaves are stimulated by heavy rain, they close to reduce the damage of the rain. Also, when insects climb up and want to eat the leaves, the leaves will close.
