Stimuli itself is of two types - external stimuli and internal stimuli. External stimuli refers to touch, pressure, heat etc. Internal stimuli refers to the stimuli produced by body components - like hormones etc.
Sunlight can be considered a stimulus because it is a source of energy that triggers responses in living organisms. For example, sunlight can stimulate plants to photosynthesize and grow, while in humans, exposure to sunlight can trigger the production of vitamin D in the skin.
Plants are not able to support their own weight because they don't have an internal skeleton like animals do. Instead, they rely on external support structures like the cell wall, interlocking branches and roots, and external support from other plants or structures. Plants also lack muscles and therefore the ability to actively move and contract to support their own weight. The main reasons why plants can't support their own weight are: No internal skeleton Reliance on external support Lack of musclesWithout these key components, plants are unable to develop the strength and resilience to support their own weight.
Indian scientist Sir Jagadish Chandra Bose conducted pioneering research that demonstrated that plants respond to external stimuli. He observed and recorded plant responses to various stimuli such as light, sound, and touch, laying the foundation for the field of plant physiology.

An example of an external stimulus for a plant is light, which influences growth direction through phototropism, causing plants to bend toward the light source. An internal stimulus could be the plant's hormonal response to stress, such as the production of abscisic acid in response to drought, which triggers stomatal closure to conserve water. Both types of stimuli play crucial roles in a plant's survival and adaptation.
Tropism is the response plants have towards external stimulus.

due to their internal and external structures
Tropism is the movement of a plant away from or toward a stimulus. The most easily found example of tropism is a plant's response to light. Plants tend to grow toward the light. This tendency is called 'phototropism'.
An example of external stimuli is a loud noise that causes someone to cover their ears or flinch in response.
There are a few things that all plants must manage. Plants must manage water intake and internal temperatures for example.
Sunlight can be considered a stimulus because it is a source of energy that triggers responses in living organisms. For example, sunlight can stimulate plants to photosynthesize and grow, while in humans, exposure to sunlight can trigger the production of vitamin D in the skin.
