Neco 2022 Agricultural Science Question 25
Practice objective / multiple choice question 25 from the 2022 Neco Agricultural Science examination.
The diagram shows a mature maize plant with the six labelled parts: 1\,root system, 2\,stem, 3\,leaf blade, 4\,leaf sheath, 5\,tassel and 6\,ear. At maturity the total dry matter of the plant is 800\,g and, under normal conditions, it is distributed as follows: roots 15 %, stem 25 %, leaf blade 30 %, leaf sheath 10 %, tassel 5 % and ear 15 %. A disease reduces the leaf‑sheath dry matter by 40 % of its normal amount, and the lost dry matter is redistributed proportionally among the remaining parts. What is the new dry‑matter weight (in grams) of the ear?
