Question

The roots of a sunflower plant growing downwards while the shoot grows upwards and the flower turns towards the sun are examples of what characteristic of all living organisms?

a. They reproduce using DNA.
b. They evolve through time.
c. They make their own energy.
d. They sense the environment and respond to it.

Answer 1

Option (d), The sunflower's growth responses to gravity and light are examples of how living organisms sense and respond to their environment, which is a fundamental biological adaptation.

Step-by-step explanation:

The roots of a sunflower plant growing downwards, the shoot growing upwards, and the flower turning towards the sun illustrate the characteristic of living organisms to sense the environment and respond to it. This response to environmental stimuli is a type of adaptation that is favored by natural selection because it increases the organism's chance of survival and reproduction.

Unlike animals, plants lack a nervous system but use chemical control mechanisms, such as hormones, to respond to changes in their environment.
