1.	Aim:Identification of tissue in collected sample.Apparatus:Microscope, slide, dilute HCl, forceps, brush.Procedure:1. Collect a small piece of chicken with bone from your nearby chicken centres or market. 2. Put it in dilute HCl for two hours. 3. Take the skin part of chicken piece. 4. Place the material with forceps or brush on the slide 5. Then keep the another slide on it and press both the slides gently. 6. Place a cover slip tap on it and observe under microscope. 7. Draw the diagram of what you have observed under microscope in your notebook. 8. Compare your diagram with the given picture.Answer these questions.1. Are all the cells similar?2. How are they arranged?3. Are these cells tightly packed and formed as continuous sheath?4. Is there any intercellular space?5. Think, why these cells look like continuous sheath.6. Does this tissue covering protect inside and outside of the animal body?
Answer» 1) Yes. All the cells are similar. 2) They are arranged in layers. Each cell is round and nucleated. Observed diagram 3) Yes. The cells are tightly packed and formed as continuous sheath. 4) No. There is no intercellular space. 5) These cells are look like continuous sheath because there is no intercellular space and the cells are tightly packed. 6) Yes. This tissue covering protect inside and outside of the animal body.
