If a plant is grown in the absence of gravity, which type of phototropism will its roots exhibit, and where will auxin accumulate?
(1 point)
o positive phototropism; auxin will accumulate on the side nearest to the light source
O negative phototropism, auxin will accumulate on the side away from the light source
O positive phototropism; auxin will accumulate on the side away from the light source
O negative phototropism; auxin will accumulate on the side nearest to the light source

normally, roots exhibit negative phototropism and positive geotropism. but with the absence of gravitational force, there's no way there will be negative geotropism

If a plant is grown in the absence of gravity, roots will exhibit NEGATIVE PHOTOTROPISM, and auxin hormone will accumulate on the side away from light.

Phototropism can be defined as the growth or movement of an organism (e.g., a plant) in response to light stimuli.

Phototropism may be caused by specific stimuli and chemicals such as hormones.

Positive phototropism occurs when a plant (or its parts) grows towards the light source, whereas negative phototropism occurs when a plant grows away from the light source.

In conclusion, if a plant is grown in the absence of gravity, roots will exhibit negative phototropism, and auxin hormone will accumulate on the side away from light.
