Answer:
D. The substances utilized in response to light are produced in the terminal bud.
Explanation:
The substances which are produced in the apical meristem are known as the auxins. are responsible for solar tracking in plants. are a powerful growth hormone that are produced naturally by plants. They are mainly found in shoot and root tips and promote cell division, stem and root growth. They also drastically affect plant orientation by allowing cell division to one side of the plant in response to sunlight and gravity. That response to sunlight by the hormone is know as phototropism where the plant would move towards the source of light which promote its growth. The movement of auxins due to gravity it is known as geotropism where the hormones moves to one side of the root in response to gravity.
