(Credits 2)

 

  1. Work out: Microscopic preparation, drawing and labelingof Chlamydomonas, Chara,Ectocarpus, Rhizopus and Ascobolus
  2. Anatomical studies (following double staining method) of: 2a. Stem- Cucurbita, sunflower and maize. 2b. Root- Colocassia, gram and orchid. 2c. Leaf- Nerium
  3. Identification with reasons: 3a. Cryptogamic specimens (macroscopic/microscopic as prescribed in the theoretical syllabus. 3b. Pathological specimens (herbarium sheets)of Late blightof potato, Brown spot of rice and stemrot of jute.
  4. Laboratory records: Laboratory note books (regularly signed) and slides (prepared in class) are to be submitted at the time of Practical Examination. Regular attendance in the class must be credited.
  5. Atleast one local excursion to be conducted to give an idea of plant diversity, habitat of algae and fungi
