WAEC Biology 2014 Theory — Question 9

Model answer

Venus flytrap: The plant has modified leaves forming a hinged trap lined with sensitive trigger hairs. When an insect touches the trigger hairs, the trap snaps shut, enclosing the prey. The plant then secretes digestive enzymes that break down the insect's soft tissues, and the resulting nutrients (particularly nitrogen compounds) are absorbed by the leaf, supplementing the plant's nutrition since it typically grows in nitrogen-poor soils.
