Minerals for Plant

What is the role of nitrogen in plant growth?

• Nitrogen is essential for plant growth.

• Nitrogen is harmful to plants.

• Nitrogen inhibits plant growth.

• Nitrogen has no role in plant growth.

Why is phosphorus important for plants?

• Phosphorus is important for plants because it plays a crucial role in energy transfer and storage, photosynthesis, and the formation of DNA and cell membranes.

• Phosphorus is harmful to plants

• Plants can survive without phosphorus

• Phosphorus has no effect on plant growth

What are the functions of potassium in plants?

• Potassium has no functions in plants.

• Potassium inhibits water balance, deactivates enzymes, hinders photosynthesis, reduces transportation of sugars and starches, weakens disease resistance, and breaks down cell walls.

• Potassium regulates water balance, activates enzymes, promotes photosynthesis, enhances transportation of sugars and starches, improves disease resistance, and strengthens cell walls.

• Potassium only functions in the growth of roots and stems, but not in other parts of the plant.

Which mineral is responsible for promoting leaf and stem growth in plants?

• nitrogen

• potassium

• phosphorus

• carbon

How does nitrogen affect the color of plant leaves?

• Nitrogen inhibits chlorophyll production.

• Nitrogen has no effect on the color of plant leaves.

• Nitrogen causes plant leaves to turn yellow.

• Nitrogen promotes chlorophyll production.

What happens to plants when they lack phosphorus?

• Plants grow taller and faster

• Plants develop stronger stems and leaves

• Plants experience stunted growth, reduced flowering, and poor root development.

• Plants produce more flowers and fruits

Which mineral is essential for the formation of flowers and fruits in plants?

• phosphorus

• iron

• nitrogen

• calcium

How does potassium help in regulating water balance in plants?

• Potassium helps in transporting water from the roots to the leaves.

• Potassium helps in converting water into glucose through photosynthesis.

• Potassium helps in reducing water loss through transpiration in plants.

• Potassium helps in maintaining osmotic potential and regulating stomata opening and closing.

What are the symptoms of nitrogen deficiency in plants?

• Stunted growth, yellowing of leaves (chlorosis), and reduced fruit or flower production.

• Wilting of leaves, increased fruit or flower production, and dark green leaves.

Why is phosphorus important for seed development in plants?

• Phosphorus is important for energy transfer, DNA synthesis, and cell division.

• Phosphorus has no role in seed development in plants.

• Phosphorus is only important for root development in plants.

• Phosphorus is harmful to seed development in plants.
