The relationship between support systems and stability in plants (1)

A plant is said to be stable in its position if it does not fall easily

The relationship between support systems and stability in plants (2)

The plant stability is influenced by the centre of gravity and the base area

The relationship between support systems and stability in plants (3)

The lower the centre of gravity, the more stable the plant
