Question

When comparing a developing leaf with a fully mature leaf,the developing leaf will have
A)a lower water content.
B)higher nutrient levels.
C)a lower DNA content.
D)a higher photosynthetic rate.
E)a lower gas exchange rate.

Accepted Answer

Developing leaves have higher nutrient levels as they are actively growing and require more nutrients for cell division and expansion. Mature leaves have already reached their full size and may have lower nutrient requirements. The other choices are incorrect; developing leaves typically have a higher water content to support growth, a similar or higher DNA content to maintain cellular processes during growth, a lower photosynthetic rate as they haven't fully developed chloroplasts yet, and a similar gas exchange rate as they still need to exchange gases for respiration.
