Nutrition in Living Organisms Plants Class 7

March 4, 2023 | by Sravani Pathakamuri | Posted in FAQ's

In class 7, students typically learn about the basics of plant nutrition. Here are some key points:

  1. Plants are autotrophs, which means that they can produce their own food through the process of photosynthesis. They use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen.
  2. Plants have specialized structures called chloroplasts that contain chlorophyll, which is the pigment that absorbs light during photosynthesis.
  3. Besides photosynthesis, plants also require nutrients for growth and development. These nutrients are obtained from the soil, and they include macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as iron, zinc, and magnesium.
  4. The roots of plants absorb water and minerals from the soil. The water is used in photosynthesis and other metabolic processes, while the minerals are used as building blocks for the plant’s tissues.
  5. In addition to water and minerals, plants also require other non-nutrient substances such as oxygen and carbon dioxide for respiration.
  6. Some plants are carnivorous and obtain nutrients by trapping and digesting insects and other small animals.

Overall, plant nutrition is a complex process that involves multiple factors, including photosynthesis, soil nutrients, and specialized plant structures.
