CBSE Class 12 Biology Practical Syllabus 2018 – 2019

As students are revising for the upcoming CBSE Class 12 board exams, having the knowledge of a detailed CBSE syllabus for Class 12 would definitely help. In this article, we shall provide you with the CBSE Class 12 syllabus for Biology. This will help students preparing for NEET as well, the medical entrance exam conducted by CBSE. The syllabus for NEET is same as that of CBSE syllabus of Class 11 and 12. Read on to find out the detailed CBSE Class 12 syllabus for Biology.

 Practicals: Evaluation Scheme and List of Experiments                                

Time allowed: 3 hours                                                                                     Max. Marks:30

 List of Experiments

1. Study pollen germination on a slide.
2. Collect and study soil from at least two different sites and study them for texture, moisture content, pH and water holding capacity. Correlate with the kinds of plants found in them.
3. Collect water from two different water bodies around you and study them for pH, clarity and presence of any living organism.
4. Study the presence of suspended particulate matter in air at two widely different sites.
5. Study the plant population density by quadrat method.
6. Study the plant population frequency by quadrat method.
7. Prepare a temporary mount of onion root tip to study mitosis.
8. Study the effect of different temperatures and three different pH on the activity of salivary amylase on starch.
9. Isolate DNA from available plant material such as spinach, green pea seeds, papaya, etc.
10. Study/observation of the following (Spotting)
11. Flowers adapted to pollination by different agencies (wind, insects, birds).
12. Pollen germination on stigma through a permanent slide.
13. Identification of stages of gamete development, i.e., T.S. of testis and T.S. of ovary through permanent slides (from grasshopper mice).
14. Meiosis in onion bud cell or grasshopper testis through permanent slides.
15. T.S. of blastula through permanent slides (Mammalian).
16. Mendelian inheritance using seeds of different colour/sizes of any plant.
17. Prepared pedigree charts of any one of the genetic traits such as rolling of tongue, blood groups, ear lobes, widow’s peak and colour blindness.
18. Controlled pollination -  emasculation, tagging and bagging.
19. Common disease causing organisms Like Ascaris, Entamoeba, Plasmodium, Roundworm through permanent slides or specimens. Comment on symptoms of diseases that they cause.
20. Two plants and two animals (models/virtual images) found in xeric conditions. Comment upon their morphological adaptations.
21. Two plants and two animals (models/virtual images) found in aquatic conditions. Comment upon their morphological adaptations.

 TIPS  AND TRICKS:

- Study the Biology theory that will form the basis of your experiments thoroughly
- The key to scoring high marks during a Biology practical exam is diagrams. Study from diagrams, revise from diagrams and practice drawing diagrams
- Spotting section can be scoring if you are familiar with the diagrams
- Knowing how to make correct sides is very important
- Understand the syllabus comprehensively so in each experiment/spotting you know what is to be done
- Make a quick revision list for Biology practical preparation to revise the important points and concepts you need to know
- Group study is helpful while preparing, each friend can describe an experiment while others try to identify the concept used in the experiment
- Note down your experiment procedure carefully, many students lose marks while writing the project notes in a hurry

Although the Biology practical exam may seem easy, it's important to devote some time to prepare, to help you score high in the overall Biology subject; theory and practical combined.
