Overview

  • Every living organism is composed of fundamental units called cells. The shape and size of organism depends upon the arrangement of cells. A single cell is capable of performing life processes such as digestion, respiration, circulation, etc. Our touchable model takes us on an adventure exploring the small worlds of animal and plant cells.
  • Cells are the basic building block of all living organisms. Cells are tiny powerhouses that make sure living things stay alive and well.
  • Exploring the Cellular components:
  • 1. Cell Wall: The Cell Wall provides structural support and protection to plant cells. Run your fingers along this sturdy outer layer, feeling the cell's protective shield. It is rigid, semi-elastic and non-living layer.
  • 2. Cell Membrane: Also known as Plasma membrane or plasma lemma is like a vigilant gatekeeper, that controls what enters and exits, ensuring a carefully regulated environment. It acts as a selective barrier for material exchange. Cell membrane is the outermost layer of the animal cell and the second layer next to cell wall in plant cell.
  • 3. Cytoplasm: Inside the cell membrane lies a jelly like substance called cytoplasm present between cell membrane and the nucleus. It contains all the cell organelles such as mitochondria, lysosome, etc. and also contains nonliving substances like proteins, food materials, etc. It provides shelter to the cell organelles and inclusions.
  • 4. Nucleus: The Nucleus is the cell's control center, housing genetic information. Feel the circular, rough structure, and understand its role as the brain center of the cell. It controls all activities such as metabolism, excretion, etc. taking place in cell.
  • 5. Vacuole: The Vacuoles are fluid filled bag-like structure present in cytoplasm of both plant and animal cell bound by membranes. It acts as the cell's storage room, holding nutrients and waste. In animal cell, they are small and scattered whereas in Plant Cell, there is a large vacuole found in the middle part of the cell. It helps to maintain balance in the amount of water, minerals and materials in the cell.
  • 6. Chloroplasts: Green plastids due to presence of chlorophyll that helps in the preparation of food through photosynthesis is called as chloroplast. It is also known as the Kitchen of Plant Cell.
  • 7. Leucoplast: Colorless plastids which are round in shape is known as leucoplast. Due to leucoplast, certain parts of plants are white. They store food in the form of carbohydrate, proteins and fats. It also produces aleurone layer which helps in the growth and development of seeds.
  • 8. Endoplasmic Reticulum: It is a transportation system within the cell. It is a network of hollow tubular structures in the cytoplasm running from nucleus to cell membrane. It is found in both Animal and Plant cell forming the endoskeleton of the cell. It is of two types: Smooth Endoplasmic Reticulum and Rough Endoplasmic Reticulum.
  • 9. Mitochondria: In the cytoplasm of both animal and plant cells, there is a spherical rod like cell organelles called mitochondria which is also the powerhouses producing energy for the cell. It also helps to produce hemoglobin, calcium and fatty acids.
  • 10. Golgi Apparatus: It acts as the cell's packaging center, modifying and packaging proteins for export.
  • 11. Lysosome: Lysosomes are Sac- like cell organelle present in the cytoplasm of animal cells and generally absent in plant cell. It acts as the cell's cleanup crew, breaking down waste and provide nutrients to the seed during germination.
  • 12. Microfilament: Microfilaments are tiny threads providing structure and support.
  • 13. Centrosome: It is a star shaped cell organelle present near the nucleus in the cytoplasm of animal cell. The Centrosome is essential for cell division, organizing the cell's architecture. It is present in an animal cell but absent in the plant cell.
  • 14. Microtubule: Microtubules act as the cell's highways, transporting materials.
  • 15. Intermediate Filament: Intermediate Filaments provide structural stability to the cell.
  • 16. Peroxisome: Peroxisome is the cell's recycling bin, breaking down harmful substances.
  • 17. Ribosome: They are minute spherical organelles found in the cytoplasm. Ribosomes are the cell's protein builders, creating essential proteins. There are two types of ribosomes: 70S and 80S. It enhances the function of RNA and participates in gene expression.
