When the auxins in the plant act towards gravity... positive geotropism is wen the plant goes to the direction of gravity which would be downwards..negative geotropism would be upwards going against the natural gravity
Phototropism is when the plant reacts towards the photosynthesis conditions where when light acts on the plant so the auxins burst and the plant bends towards light..this is positive phototropism...but when the plant goes against the direction of light it is then negative phototropism
What else can I help you with?
How are geotropism and phototropism similar?
Both geotropism and phototropism involve plant growth responses to external stimuli. Geotropism is a plant's growth response to gravity, which helps roots grow downward and stems grow upward. Phototropism is a plant's growth response to light, guiding plants towards a light source for photosynthesis. Both tropisms aid plants in optimizing their growth and development.
Stems and leaves grow using positive what?
stems and leaves grow using positive phototropism. That means growing towards the source of light. Mostly we reffer to the sun in this case. Even so, stems and roots can as well grow away from the source of light, that is negative phototropism.
Which response is result of geotropism?
Growth of plants toward the light is called phototropism. Growth of plants in response to gravity is called geotropism or gravitropism.
Which part of the radish plant controls phototropism?
It is the green part.Leafy part of the radish
What are some examples of negative geotropism?
A few examples of negative geotropism in plants include roots growing upwards in response to gravity (negative gravitropism), stems bending away from the ground to grow upwards (negative phototropism), and leaves folding upwards in response to touch or vibration (negative thigmotropism).
What is a non example of geotropism?
For example a pot that has not fallen down

Do animals also show phototropism and geotropism give examples?
only plants no animals
What is the growth of plant roots down word and shoots upward called?
Elongation of the meristematic tissue
What are kinds of tropism?
phototropism-responce to llight geotropism-responce to gravity thigmotropism-responce to touch hydrotropism-responce to water
What is the difference between phototropism and geotropism?
Phototropism - towards light. Think plants, flowers, leaves. They generally turn towards light.Geotropism - towards the earth. Go figure.Hydrotropism - towards water or towards moisture.

How do plants respond to external stimuli such as geotropism phototropism and hydropotism?
Plants respond to external stimuli through various growth movements known as tropisms. In geotropism, roots grow downward in response to gravity, while stems grow upward. Phototropism involves plants bending towards light sources to maximize photosynthesis, and hydrotropism directs roots toward moisture in the soil. These responses are regulated by plant hormones, such as auxins, that facilitate differential growth.
The name of the response of plants to light?
a "tropism"; geotropism for response to gravity and phototropism for response to light
