NIOS Class 10 Science Activity 21.3 Building Blocks of Life- Cell and Tissues

In this activity, we will make a three-dimensional model of a plant cell or an animal cell using easily available materials.

 

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 prepare a model of a plant cell or an animal cell

Materials Required

    1.  Thermocol sheet / thick cardboard

    2. Coloured wool

   3. Bindis of different sizes and colours

   4. Cotton

   5. Straws

   6. Clay

   7. Glue

   8. Marker

Procedure

We take a thermocol sheet or cardboard as the base of the model. Now we use insulation wires or wool to make an oval or circular outline to represent the cell membrane.

We make a smaller circle to represent the nucleus and fill the inner space with cotton to represent the cytoplasm.

We use bindis or clay to show different organelles like mitochondria, ribosomes and Golgi body, etc.

In a plant cell, we will make the cell wall, chloroplast and a large vacuole. Now we will label all parts with a marker.

Result

 A well-labelled and clear colourful model of a plant or animal cell is prepared.

Conclusion

This activity helps in understanding the cell structure and functions of cell organelles. We can easily identify various cell organelles and understand the difference between plant and animal cells
