What is Photosynthesis?

Photosynthesis is a process in which green plants use energy from the sun to convert carbon dioxide and water into sugar or other energy-rich molecules. This sugar can then be used as an energy source for plant growth, making photosynthesis essential for plant health. During this process, oxygen is also produced, acting as an important byproduct that's vital to life on earth.

What are the Processes Involved in Photosynthesis? 

Photosynthesis is broken down into two phases: the light-dependent reactions and the Calvin cycle (light-independent reactions). In the light-dependent reactions, energy from sunlight is captured by pigments such as chlorophyll and converted into a form of chemical energy called ATP. This process happens in the thylakoid membrane of the organelle known as a chloroplast. In the light-independent phase, ATP and other molecules from the light-dependent phase are used to synthesize sugar from carbon dioxide. This process takes place in the stroma of the chloroplast.

How do Plants Absorb Minerals?

Plants absorb minerals through their roots, which means they can obtain the necessary elements to grow and survive. To do this, roots take in minerals from the soil via osmosis and diffusion, then transport them to other parts of the plant. This process involves using root hairs and other specialized root structures to take up water efficiently, often via active transport where energy is expended in order to move minerals into the cell.

What Role do Water, Sunlight and Carbon Dioxide Play in Plant Nutrition?

Water, sunlight and carbon dioxide all play an important role in the nutrition of plants. Water is essential for the uptake of minerals by the roots and is transported throughout the plant via a process called translocation. Meanwhile, photosynthesis requires both light and carbon dioxide to drive the conversion of sunlight into chemical energy stored as sugar. This sugar is then used as fuel for growth or respiration, or can be stored in specialised structures like fruits and seeds.

If you're a student in Class 7 studying Science, you'll know how important it is to practice and revise concepts regularly. One effective way to do this is by solving worksheets that cover topics in detail. Specifically, if you're studying Chapter 1 of Class 7 Science, which focuses on nutrition in plants, you'll find that solving worksheets on this topic can help you master the subject better. Fortunately, there are many resources available online that offer free, downloadable worksheets on this topic. For instance, you can easily find a Nutrition in Plants Class 7 Worksheet, a Class 7 Science Chapter 1 Worksheet, or a Worksheet on Nutrition in Plants Class 7, with just a simple search. These worksheets come with answers and are available in PDF format, making them easy to print and use. By solving these worksheets, you can not only test your understanding of the concepts but also improve your ability to recall information accurately.

Additionally, if you're looking for a worksheet that covers a broader range of topics related to plants, you can find those too. For example, a Worksheet on Plants for Class 1 can help younger students learn about the different parts of plants, their functions, and the importance of plants to the environment. Similarly, a Things we Get from Plants Worksheet can teach students about the various products we derive from plants, such as food, medicine, and materials for clothing and shelter. Moreover, if you want to take your learning to the next level, you can opt for a Science Worksheet, Nutrition in Plants for Class 7 Worksheet with Answers MCQ. This type of worksheet typically includes multiple-choice questions that test your knowledge of the subject more rigorously.

FAQs on Nutrition in Plants 


  1. What is Nutrition in Plants? Nutrition in Plants is the process by which plants make their food by utilizing sunlight, carbon dioxide, water, and mineral salts from the soil.

  2. What is photosynthesis? Photosynthesis is the process by which green plants make their food by using sunlight, water, and carbon dioxide to produce glucose and oxygen.

  3. What are chloroplasts? Chloroplasts are specialized organelles present in green plant cells that contain chlorophyll and other pigments that are responsible for trapping light energy for photosynthesis.

  4. How do non-green plants obtain their food? Non-green plants obtain their food by parasitism, saprophytism, or by forming associations with other plants.

  5. What are the different modes of nutrition in plants? The different modes of nutrition in plants are Autotrophic, Heterotrophic, Parasitic, and Saprophytic.

  6. What is transpiration? Transpiration is the process by which water is lost from the leaves of the plant in the form of water vapour.

  7. What are the different types of roots in plants? The different types of roots in plants are Taproots, Fibrous roots, and Adventitious roots.

  8. What is the role of stomata in plants? Stomata are tiny pores present on the leaves of plants that allow for the exchange of gases, such as carbon dioxide and oxygen.

  9. What is the importance of water in plants? Water is essential for plants as it helps in the absorption of minerals from the soil and the transportation of nutrients throughout the plant.

    It also helps in maintaining the turgidity of the plant cells.

  10. What are the products of photosynthesis? The products of photosynthesis are glucose and oxygen
