You must have read in your Science books about photosynthesis. Photosynthesis is the process by which plants make their food. The chlorophyll pigment of green leaves traps sunlight. The hungry plants use this sunlight, carbon dioxide, and water to make sugars for themselves.
That’s what every book tells you, right? You will be shocked to know that this is not the true definition of photosynthesis.
Furthermore, there are 4 more photosynthesis myths you need to stop believing right now. Let us clear out these 4 myths about photosynthesis.
Myth 1: Photosynthesis can only occur in Sunlight.
That’s the biggest myth about photosynthesis. Plants use light energy from the sun to carry out photosynthesis. If they get artificial light that looks like sunlight, photosynthesis will also happen.
Myth 2: Only plants make food by photosynthesis.
No, that is not true. Even some bacteria and microorganisms can do that. The slippery green Algae make their food by photosynthesis.
Which other organism makes its food? Phytoplankton is an alga found under the ocean that makes its own food through photosynthesis.
Myth 3: Photosynthesis takes place only in the green parts of plants.
Have you seen plants with red, yellow, purple, and brown leaves? How will they live without food? Such plants also make food by photosynthesis. So, photosynthesis does not take place in green leaves only. Food is also prepared in green stems.
Myth 4: All plants make food by photosynthesis.
Some parasitic plants do not make food by photosynthesis. Then what do they eat? They take nutrients from other plants. So, not all plants make food by photosynthesis like,
Indian Pipe, etc.
Did you realize that you just learned the Class 7 Science NCERT topic, Photosynthesis? This will clear your doubts about Nutrition in Plants. Now that you have understood this Class 7 Science CBSE syllabus topic, how about taking a quick science revision test and covering your chapters for the exam?
