Plant Disease

Plants synthesize proteins, absorb nutrients, and perform photosynthesis to grow. They can suffer from insect infestations, viral and fungal infections, and nutrient deficiencies. Aphids and TMV are examples of pests and viruses that harm plants. Nutrient deficiencies like nitrogen and magnesium affect growth. Plants have physical and chemical defenses to combat infections, and identification methods include manuals and testing kits.

Explain the concept of nutrient deficiency in plants and provide examples.
