CBSE Class 10th Board Examination for Science is due to be held in March, 2025. Now, the students who are about to appear for the exams must be done with their syllabus and revision but there might be one thing which must be still left to revise and that are diagrams.
Diagrams are one of the most scoring questions in the Science Paper. Check this article to know about the list of the important topics that can be referred for tomorrow’s exam.
List of the Important Topics for Diagrams
For Biology
- Structure of Brain: Proper structure of brain wherein, you have to mention the Forebrain, Midbrain and Hindbrain.
- Human Excretory System: In this diagram you have to show all the parts of the system which includes two kidneys, urethra, ureters etc.
- Human Digestive System: Here you have to show the full process of digestion. You have to mention the mouth, liver, gallbladder, stomach, pancreas, small and large intestine, liver etc.
- Structure of Heart: In this diagram, you have to show all the veins and arteries.
- Human Respiratory System: In this diagram, the students have to show the parts which help in respiration such as nasal cavity, pharynx, larynx, epiglottis, lungs etc.
- Human Male and Female Reproductive Organs: In these diagrams, you have to depict all the parts that all together make a reproductive system.
- Nutrition in Amoeba: The students have to show how food is digested by Amobea – an unicellular organism.
- Regeneration in Planaria and Hydra: Regeneration is the part of reproduction where a part of any organism is cut, and can produce other organisms. In this diagram you have to show the regeneration process in Planaria and Hydra.
- Structure of a Flower or Pollination in Flowers: Here you have to depict the structure of flowers with proper labelling. You have to draw and label parts like pistil, stamen etc.

Quick Revision Tips for the Attempting the Questions with Diagrams
- Carry the proper stationery to attempt the question well and to avoid any chaos at the time of examination.
- Do the proper labelling of your diagram as the marks is not just for drawing the diagram but for doing the proper labelling.
- Draw the diagram neatly. Avoid erasing the diagram again and again.
- Draw the diagram from HB pencils as they are lighter in texture and do not leave any mark after erasing.
- You can use black / blue pen to write the parts of the diagram but use a pencil only to draw the structure.
