Question 1 Report
A conservation team on an island uses Fig. 1 to study a rare pitcher plant. Insects fall into a liquid held by the modified leaf. Glands in the leaf release digestive enzymes, and the plant absorbs mineral ions from the insect's body. This helps it grow in soil with very little nitrate.
(a) Identify the organ of the plant modified to make the pitcher. [1]
(b) Explain why the plant benefits from digesting insects in nitrate-poor soil. [2]
(c) Which substance made by the plant contains nitrogen and is needed to make new cells? [1]
(d) Use the figure to identify the tissue that carries water to the pitcher. [1]
Answer Details
(a) Leaf [1] (b) Insects provide nitrate ions / a source of nitrogen [1]; nitrogen is needed for growth / making proteins [1] (c) Protein [1] (d) Xylem [1]
