In the majority of such situations, it is called "falling".
tropism
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.
when the fixed part of a stationary plant moves in response to a stimulus the reaction is known as tropic movement.or the movement in which fixed part of stationary plant moves in response to a stimulus is known as tropic movement or tropism.
Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
mass movement, also called Mass Wasting, bulk movements of soil and rock debris down slopes in response to the pull of gravity, or the rapid or gradual sinking of the Earth's ground surface in a predominantly vertical direction. Formerly, the term mass wasting referred to a variety of processes by which large masses of crustal materials are moved by gravity from one place to another.
Geotropism is the growth or movement of an organism in response to gravity. It can be positive (growth towards gravity) or negative (growth away from gravity). This phenomenon helps plants orient themselves for optimal growth and development.
The roots of a plant grow downward in response to gravity. This is called positive gravitropism or positive geotropism. Roots grow toward the pull of gravity while shoots grow away from the force of gravity.
Tactic movement in plants refers to their ability to grow and orient themselves in response to external stimuli such as light, gravity, and touch. This movement helps plants optimize their growth and maximize their chances of survival by adjusting their growth direction and position according to varying environmental conditions. Examples of tactic movements in plants include phototropism (growth towards light), gravitropism (response to gravity), and thigmotropism (response to touch).
