Question 2
Structure of Flowering PlantsThe diagram below is an illustration of a mango leaf drawn by a student in a Biology test. The student failed the test. The likely reason why the student failed the test was that the
- A.labels were wrong and the guidelines were not touching the structures.
- B.net venation shown were few, rough, not properly drawn and wrongly placed.
- C.leaf was too tapered at the apex, the leaf stalk was too short and the shape of the leaf was wrong.
- D.leaf venation should have been parallel and the midrib should be thicker.
Show the answer and explanation
Answer: A (labels were wrong and the guidelines were not touching the structures.)
Explanation
In the drawing, the labels point to the wrong parts (for example 'margin' and 'vein' do not touch the edge or a vein) and guidelines stop short of the structures. Correct labels and guidelines that touch the part are basic rules of biological drawing.
