🚀 Course Title: Nutrition In Plants Chapter 1 Class 7 Science 🌱

📚 Course Description:

Are you ready to dive into the fascinating world of how plants sustain themselves? In this course, we'll explore the intricacies of plant nutrition and understand why it's crucial for all organisms. Join us as we unravel the mysteries behind the processes that power life on Earth! Here's what you can expect to learn:

🚀 Understanding Nutrition in Plants:

• 🧐 Why Do Organisms Need Food? Discover the fundamental role of nutrition for survival and growth.
• 🌍 Parasite vs. Saprotroph: Learn the difference between a parasitic organism that lives off another organism and a saprotroph that breaks down dead organic matter.
• 🔬 Testing for Starch in Leaves: Get hands-on with a simple experiment to detect starch, the stored energy of plants.
• 🌱 Synthesis of Food in Green Plants: Uncover the step-by-step process by which green plants create their own food.
• 🖼️ Plants as Ultimate Source of Food: Through a detailed sketch, visualize how plants are at the base of the food chain.

🎓 Key Concepts Covered:

• Filling in the Blanks: Complete the sentences with the correct scientific terms:

  • (a) Green plants are called __________ since they synthesize their own food. (Answer: Autotrophs)
  • (b) The food synthesized by plants is stored as __________. (Answer: Starch or Glucose)
  • (c) In photosynthesis, solar energy is absorbed by the pigment called __________. (Answer: Chlorophyll)
  • (d) During photosynthesis, plants take in ______________________ and release __________________ gas. (Answer: Carbon dioxide, Oxygen)

• Identify the Plants: Recognize various types of plants and their nutritional characteristics:

  • (i) A parasitic plant with yellow, slender and branched stem is called __________. (Answer: Cuscuta)
  • (ii) A plant that is partially autotrophic could be described as __________. (Answer: Heterotrophic or Mixotrophic)
  • (iii) The pores through which leaves exchange gases are called __________. (Answer: Stomata)

• True or False: Test your knowledge with statements related to photosynthesis and plant nutrition:

  • (i) Carbon dioxide is released during photosynthesis. (False, CO2 is absorbed)
  • (ii) Plants which synthesize their food are called saprotrophs. (False, they are called autotrophs)
  • (iii) The product of photosynthesis is not a protein. (True, it's glucose primarily)
  • (iv) Solar energy is converted into chemical energy during photosynthesis. (True)

• Multiple Choice Questions: Make informed decisions based on your understanding of plant biology:

  • Which part of the plant takes in carbon dioxide from the air for photosynthesis? (Answer: Leaves, specifically through stomata)
  • Plants take carbon dioxide from the atmosphere mainly through their: (Answer: Leaves)

• Real-World Application:

  • 🌞 Greenhouses and Farming: Discover why farmers grow many fruits and vegetable crops inside large greenhouses. We'll explore the advantages of controlled environment agriculture, such as extending the growing season, protecting crops from harsh weather, and enhancing yields through regulated conditions.

By the end of this course, you'll have a solid understanding of how plants obtain their food and why this process is so vital to life on Earth. Prepare to be amazed by the ingenuity of nature and the resilience of green plants! 🌱✨
