Plant Nutrition starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plant Nutrition.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A plant is grown in a nutrient solution lacking iron. What symptoms would you expect to observe?
Describe the difference between macronutrients and micronutrients in plant nutrition.
Describe the process of mineral ion absorption in plants.
Describe the process of symbiotic nitrogen fixation in legumes.
Describe the role of leghemoglobin in nitrogen-fixing root nodules.
Describe the role of mycorrhizal fungi in plant nutrition.
Explain the difference between essential and beneficial elements in plant nutrition.
Explain the importance of potassium in plant metabolism.
Explain the role of nitrogen in plant nutrition.
Explain the role of sulfur in plant nutrition.
Explain why deficiency symptoms of mobile nutrients appear first in older leaves.
Explain why hydroponics is useful in studying plant nutrition.
Explain why iron is considered a micronutrient even though it is vital for chlorophyll synthesis.
Name two symptoms of potassium deficiency in plants.
A hydroponic experiment is set up with two groups of tomato plants. Group 1 receives a complete nutrient solution, while Group 2 receives a solution lacking boron. After three weeks, Group 2 shows poor fruit set and abnormal root growth. Explain the physiological basis for these observations.
A plant is exposed to a soil environment with high sodium concentration. Discuss the potential effects on nutrient uptake and plant health, and describe one adaptation that some plants use to cope with such conditions.
A researcher is studying two plant species: Species A grows well in soils with low zinc concentration, while Species B shows stunted growth and chlorosis under the same conditions. Explain the possible physiological or genetic mechanisms that could account for the difference in zinc uptake and utilization between the two species.
Describe the role of the Casparian strip in regulating the movement of mineral nutrients into the vascular system of roots.
Explain how the deficiency of phosphorus can affect the energy transfer processes in plant cells at the molecular level.
Explain how the process of ion exchange at the root-soil interface facilitates the uptake of mineral nutrients by plants.
