Problem: As you know cell is basic structural and functional unit of life, All organisms from bacterial to blue whales are made of cells. Basically there are two types of cells Basically there are two types of cells: Prokaryotic and Eukaryotic.

In Prokaryotic, pro means (first formed) karyote means (nucleus): Genetic material DNA is not surrounded by a membrane or it is scattered in the cytoplasm. EG: bacteria. In Eu (true) karyote (nucleus): Genetic material DNA is surrounded by a nuclear membrane. The other major difference is the present of organelles like mitochondria, Golgi apparatus etc in eukaryotes or division of labor is there. Imagination is the key in understanding this wonderful minute structure that make us alive. Here we are going to compare a Eukaryotic cell to a factory.

A cell uses various materials and produces many products for the survival just like a factory. In a factory there are different sections: organelles can be compared to different sections of a factory.

1. Nucleus: is comparable to the the headquarters of a factory where managers will give timely instruction for the smooth running of the factory. It is separated from the rest of factory especially working area. Inside cell nucleus is the instruction center, where instruction for the synthesis of products or proteins is coded. It is protected by a nuclear membrane, ensuring its protection from the rest of the cell.
2. DNA or chromosomes: It is the code or instruction for the making of products or proteins
3. Mitochondrion: It is the power house of the cell producing energy for all cell activities. In a factory it is the main electric station in the factory where energy or electric current is supplied to different stations in the factory for day to day activities.
4. Endoplasmic reticulum: First production site. It is the immediate site to the geadquarters where the products are produced. Products are to modified or polished before release. RER has ribosomes (workers) on the surface responsible for protein synthesis (products). It has continuous connection with the nuclear membrane.
5. Chloroplast present only in plant cell where food is produced just like "kitchen: or food production center in the factory. The process is photosynthesis.
6. Golgi apparatus: It is the sorting center of the cell where proteins are chemically tagged to reach the correct location. In factory, it is the site where products are classified and addressed.
7. Vesicles: Proteins are transported to the correct destinations by vesicles. In factory, the packaging and transportation of products to the exit site.
8. Cell membrane: It is the wall or boundary of the cell and has specialized channel for entry and exit guarded by proteins. Just like factory compound wall and the guarded gate.
9. Lysosome: incinerator of the cell where waste material are disposed and degraded

Question:

Compose an analogy describing the components of the cell and their functions.
