DEVELOPMENTAL BIOLOGY

The students will be able to

CO1: Critically analyse the mechanism of development ofan individual from a single cell zygote

CO2: Conjecture the process of fertilization, types of cleavage, stages and cellular mechanisms for gastrulation.

CO3: Interpret organogenesis in Chick, Extra embryonic membranes, Types & physiology of the placenta

CO4: Relate the Role of Hormones in metamorphosis

CO5: Judge the role of various teratogens

 

The approach in  teaching: 

Interactive Lectures,  Discussion, Tutorials,  Reading assignments,  Demonstration, Team  teaching 

Learning activities for  the students: 

Self-learning assignments,  Effective questions,  Simulation, Seminar  presentation, Giving tasks,  Chart or model preparation

Class test  

Semester end  examinations, Quiz,  

Assignments,  Presentation 

Surprise test 

Open book test
