NIOS Class 10 Science Activity 21.5 Building Blocks of Life- Cell and Tissues

In this activity, we will collect pictures of organs containing muscular, connective, epithelial, and nervous tissues.

Building Blocks of Life- Cell and Tissues Activity Solution

This activity is based on the NIOS Class 10 Science and Technology (212) Chapter 21: Building Blocks of Life - Cell and Tissues, Module 5: The Living World.

Aim

To identify the human body as containing different types of tissues.

Materials Required

   1. Science textbook

   2. Pictures

   3. Notebook and pencil

Procedure

   1. Collect pictures or draw diagrams of different human organs.

         

   2. Observe the tissues present in each organ.

   3. Write the name of the organ under each tissue category.

 

Observation

We observe that

(a)      Organs containing muscular tissue

i.     Heart

ii.   Arms and legs

iii. Stomach and intestine

(b)     Organs containing Connective tissue

i.      Bones

ii.   Cartilage (nose, ear)

iii. Blood

iv.  Tendons and ligaments

(c)       Organs containing Epithelial tissue

i.     Skin

ii.    Inner lining of mouth

iii. Inner lining of the stomach and in the intestine

iv. Blood vessels

(d)     Organs containing Nervous tissue

 i.     Brain

ii.   Spinal cord

iii. Nerves

Conclusion

We can conclude that human body organs are made up of specialised tissue. Connective tissue provides support; epithelial tissue protects the body surface, and nervous tissues control and coordinate body activities.
