Question

Which of the following scenarios accurately predicts when Plant A and Plant B will be the same height, given their initial heights and growth rates:

A) Plant A will catch up to Plant B in 2 months.
B) Plant A will never catch up to Plant B.
C) Plant A will catch up to Plant B in 1 month.
D) Plant A will catch up to Plant B in 3 months.

Answer 1

Plant A grown under blue light should grow the most because chlorophyll absorbs blue wavelengths optimally for photosynthesis, while Plant B under green light and Plant C under orange light are likely to experience less growth.

Step-by-step explanation:

The question focuses on plant growth under different colored lights and involves understanding how plants use chlorophyll for photosynthesis. Chlorophyll primarily absorbs red and blue wavelengths of light but reflects green, making plants appear green to us. Therefore, plant A under blue light is expected to have the most growth as it uses the light more efficiently than Plant B under green light or Plant C under orange light, which is less optimal for chlorophyll a and b. The overall growth is also suggested to be proportional to the original height, which impacts how different conditions, like light exposure on leaf surfaces or the effect of sunlight versus shade, might influence the growth of Plant A and Plant B.
