Cell Research Lab

Purpose:
The lab exercises will onlyow you to experience the techniques apply to investigate basic cell structure, observe differences between generalize and specialized plant, animal and protozoan cells, and to increase your observation skills.

agency:
start up 1
1.Use the onion undress given to you by the teacher and manoeuvre a drop of iodine onto the onion scrape.
2. accordingly place the skin under the microscope and observe.
