The diagram shows a mature maize plant with the following labelled parts: R (roots), S (stem), L (leaves), and E (ear). The leaves produce \(120\text{ g}\) of photosynthates each day. Of this amount, 60% is translocated to the ear, 25% to the stem and the remainder to the roots. If 80% of the ear's photosynthates are stored in the grain, calculate (a) the grams of photosynthates allocated to the ear, stem and roots, (b) the grams stored in the grain, and (c) the percentage of the total daily photosynthates that end up in the grain.

Answer Options

Correct Answer A. Ear: 72 g, Stem: 30 g, Roots: 18 g; Grain: 57.6 g; Percentage in grain: 48%
B. Ear: 72 g, Stem: 24 g, Roots: 24 g; Grain: 57.6 g; Percentage in grain: 48%
C. Ear: 84 g, Stem: 30 g, Roots: 6 g; Grain: 67.2 g; Percentage in grain: 56%
D. Ear: 72 g, Stem: 30 g, Roots: 18 g; Grain: 64.8 g; Percentage in grain: 54%
Correct Answer
A
Correct Option:
Ear: 72 g, Stem: 30 g, Roots: 18 g; Grain: 57.6 g; Percentage in grain: 48%
