How do plants respond stimuli?

The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a Biology teacher. this is bullcrap it is fake

What is the name for a plant's growth response to gravity?

Certain plants react to gravity by growing against it or towards it. It is the tropism of gravity called a geotropism. For example, if a potted plant falls over then it will continue to grow towards the sky. If a mudslide occurs and it drastically tilts the land where a tree grows, the tropism allows the tree to grow upwards. Alternatively, geotropism works for roots as well. Roots will respond to gravity by growing downwards. It can be observed that no matter which way a seed is planted the roots and the shoots respond to gravity in opposite ways. Plant hormones, auxins are responsible for this response. Phototropism is the response of plants to light.


What are protective structure of makahiya?

Mimosa (makahiya) have thorns to warn the animals and people not to go near them. Plants responses are called 'tropism'. The bending of the plant towards the light is called 'phototropism'. Plants response to gravity is called 'gravitropism' or 'geotropism'. The plants response to touch is called 'thigmotropism'. the response to a source of water is called 'hydrotropism'. Plants respond to 'environmental stimuli'. Plants responses to stimuli enable them to survive. These are the protective structure of a Mimosa and other behavioral adaptation of Plants.
