Question

A plant is left in a protected greenhouse that pumps in fresh carbon dioxide. The plant also has access to sunlight and can make its own sugar. However, the plant is beginning to die.

What is most likely missing?

water
air
multiple cells
a place to live

Answer 1

The most likely factor missing is **water**. While the plant has access to sunlight and carbon dioxide, it also needs water to carry out photosynthesis and maintain its physiological processes. Without adequate water, the plant may experience stress and begin to die despite having the other necessary conditions for growth.
