Why is nitrogen important for plant growth?

• Nitrogen is primarily used for water absorption in plants.

• Nitrogen is important for plant growth because it is essential for protein synthesis, nucleic acids, and chlorophyll production.

• Nitrogen is a key component of plant cell walls.

• Nitrogen helps plants produce flowers and fruits only.

What role does phosphorus play in plant health?

• Phosphorus helps in the production of chlorophyll only.

• Phosphorus has no significant impact on plant health.

• Phosphorus promotes energy transfer, root development, and overall plant growth.

• Phosphorus is primarily responsible for photosynthesis.

How does too much sunlight affect plant growth?

• Too much sunlight can harm plant growth by causing dehydration, heat stress, and reduced photosynthesis.

• Excess sunlight promotes faster growth in all plant species.

• Too much sunlight increases nutrient absorption in plants.

• High sunlight levels enhance the color and fragrance of flowers.

What happens to a plant if it does not get enough sunlight?

• The plant will grow faster and healthier.

• The plant will experience stunted growth and may eventually die.

• The plant will change color to a brighter shade.

• The plant will produce more flowers and fruits.

How do different types of soil affect plant survival?

• Soil type determines the color of plants.

• Soil type has no impact on plant growth.

• Soil type only affects the size of the leaves.

• Soil type affects water retention, nutrient availability, and root growth, impacting plant survival.

What is the relationship between water and soil nutrients?

• Water prevents the uptake of soil nutrients by plants.

• Soil nutrients are independent of water availability.

• Water depletes soil nutrients over time.

• Water facilitates the absorption and availability of soil nutrients for plants.
