Aplant appears to grow away from the sunlight and the roots appear to grow deeply straight down into the ground. this plant is displaying which of the following?

Phototropism is reaction of a plant to a light stimulus. Growth of the plant or its part grow towards the light stimulus is called positive phototropism. Growth of the plant or its part away from the light stimulus is called negative phototropism. Since, the plant grows away from the sunlight (away from the light stimulus), it is negatively phototropic.

Gravitropism is reaction of a plant to gravity. Growth of the plant or its part in the same direction as gravity is called positive gravitropism. Growth of the plant or its part grow in the opposite direction of gravity is called negative gravitropism. The root is positively gravitropic (grows deeply straight down into the ground, in the same direction as gravity).

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

materials water oxygen those are the things i can think of in this moment.
