a.positive phototropism and positive gravitropism

b.negative phototropism and positive gravitropism

c.negative phototropism and negative gravitropism

Answer 1

The answer is : B. Negative phototropism and positive gravitropism

Grow away from the sunlight : indicate negative phototropism. If it's positive that it will grow toward the sunlight

Grow deeply straight down into the ground : indicate positive Gravitropism

hope this helps

Answer 2

Answer - B
Phototropism is the response of plants towards the source of the light. If they grow in a direction away from the source of the light, they are exhibiting negative phototropism and if they grow towards the source of light, then it is positive phototropism. Similarly, gravitroprism is the plant's response to gravity in the same manner.
