Latest CBSE Class 11th Syllabus of Biology 2018-19

CBSE has released the CBSE Class 11th Syllabus of Biology (Code No. 044) for the session 2018-19. The new session has started and board updated the new syllabus. There is no change made in the syllabus and exam pattern.

The question paper will be of 70 marks. Practicals will be conducted of 30 marks.

The Question paper will consist of 26 questions. All questions would be compulsory. However, there is an internal choice in one question of 2 marks weightage, one question of 3 marks weightage and all the three questions of 5 marks weightage.

List of Experiments

1. Study and description of three locally available common flowering plants, one from each of the families Solanaceae, Fabacceae and Liliaceae (Poaceae, Asteraceae or Brassicaceae can be substituted in case of particular geographical location) including dissection and display of floral whorls, anther and ovary to show number of chambers (floral formulae and floral diagrams). Types of root (Tap and adventitious); stem (herbaceous and woody); leaf (arrangement, shape, venation, simple and compound). 

2. Preparation and study of T.S. of dicot and monocot roots and stems (primary).

3. Study of osmosis by potato osmometer.

4. Study of plasmolysis in epidermal peels (e.g. Rhoeo leaves).

5. Study of distribution of stomata in the upper and lower surface of leaves.

6. Comparative study of the rates of transpiration in the upper and lower surface of leaves.

7. Test for the presence of sugar, starch, proteins and fats. Detection in suitable plant and animal materials.

8. Separation of plant pigments through paper chromatography.

9. Study of the rate of respiration in flower buds/leaf tissue and germinating seeds.

10. Test for presence of urea in urine.

11. Test for presence of sugar in urine.

12. Test for presence of albumin in urine.

13. Test for presence of bile salts in urine.

B. Study/observation of the following (spotting)

1. Study of the parts of a compound microscope.

2. Study of the specimens/slides/models and identification with reasons - Bacteria, Oscillatoria, Spirogyra,
Rhizopus, mushroom, yeast, liverwort, moss, fern, pine, one monocotyledonous plant, one dicotyledonous plant and one lichen.

3. Study of virtual specimens/slides/models and identification with reasons - Amoeba, Hydra, liverfluke,
Ascaris, leech, earthworm, prawn, silkworm, honeybee, snail, starfish, shark, rohu, frog, lizard, pigeon and rabbit.

4. Study of tissues and diversity in shapes and sizes of plant and animal cells (palisade cells, guard cells, parenchyma, collenchyma, sclerenchyma, xylem, phloem, squamous epithelium, muscle fibers and mammalian blood smear) through temporary/permanent slides.

5. Study of mitosis in onion root tip cells and animals cells (grasshopper) from permanent slides.

6. Study of different modifications in roots, stems and leaves.

7. Study and identification of different types of inflorescence (cymose and racemose).

8. Study of imbibition in seeds/raisins.

9. Observation and comments on the experimental set up for showing:
a) Anaerobic respiration
b) Phototropism
c) Effect of apical bud removal
d) Suction due to transpiration

10. Study of human skeleton and different types of joints with the help of virtual images/models only.

11. Study of external morphology of cockroach through virtual images/models.
