Organelles in a cell can be compared to different structures in a city. For example, the nucleus is like a city hall, controlling activities; mitochondria are like power plants, producing energy; and the endoplasmic reticulum is like a transportation system, moving materials. Just as a city functions efficiently when different structures work together, a cell needs its organelles to work in harmony for proper function.
The model animal cell typically lacks the complex organelles and structures found in a real animal cell, such as the endoplasmic reticulum, Golgi apparatus, and mitochondria. Additionally, a model cell may oversimplify the cell membrane and nucleus, omitting details like the nuclear envelope and embedded proteins.
Real cells are microscopic and vary in size and shape depending on the type of cell and its function. They can appear round, elongated, flat, or irregular in shape with a distinct cell membrane, cytoplasm, and nucleus. Under a microscope, cells may contain organelles such as mitochondria, endoplasmic reticulum, and lysosomes.
Making real-world comparisons with cells helps to contextualize their structure and function by relating complex biological concepts to familiar objects or systems. For instance, comparing a cell to a factory can illustrate how organelles work together to produce and transport proteins, similar to how various departments in a factory coordinate to manufacture goods. This analogy simplifies the understanding of intricate processes and highlights the importance of each component in maintaining overall cellular function. Such comparisons can enhance retention and comprehension of cellular biology.
Vesicles in cells can be compared to packages or containers that transport molecules within the cell or between cells. Just like how vesicles carry cargo from one place to another in a cell, packages or containers transport goods from one location to another in the real world.
A real-life example of the cytoskeleton in action is during cell division, when it helps to organize and separate the chromosomes. The cytoskeleton provides structural support and helps the cell move and change shape, such as in muscle cells during contraction. Additionally, the cytoskeleton is involved in intracellular transport, where it helps shuttle organelles and molecules throughout the cell.
the real answer is vacuoles.

I'm not sure what you mean by real life examples, but some examples of cell organelles that exist are: Golgi Apparatus (or Golgi Body) Rough Endoplasmic Reticulum Smooth Endoplasmic reticulum Nucleus
