Worksheet Chapter 3: Nutrition in Plants

1. Explain why mineral ion absorption by root hair cells in waterlogged soil is severely reduced.

2. State two structural adaptations of root hair cells that increase their efficiency in absorbing water and mineral salts.

3. Differentiate between Parasitic plants and Epiphytic plants in terms of their impact on the host plant.

4. Distinguish between Macronutrients and Micronutrients in plant nutrition, providing one example for each.

5. True or False: Carnivorous plants digest insects primarily to meet their daily carbohydrate and glucose requirements.

6. True or False: Epiphytes are parasitic plants that steal water and minerals from the xylem of host trees.

7. A farmer notices that his corn crop displays stunted growth, with yellowing older leaves and dark purple margins on young leaves. Identify the two nutrient deficiencies present and justify your answer based on their functions.

8. Describe the physiological adaptation and nutritional strategy of the Pitcher plant (Nepenthes sp.).

9. Which macronutrient deficiency causes interveinal chlorosis, where areas between leaf veins turn yellow while veins remain green?

10. Fill in the blank: The specialized absorptive root structures produced by parasitic plants to tap into host vascular tissues are called ________.
