Specific Cells
Ribosomes
They synthesize proteins using the genetic information from messenger RNA (mRNA), which is crucial for cellular structure, function, and regulation.
Case Study 1:
Expected Answer: The organelle that could be failing is the lysosomes. Lysosomes are responsible for breaking down and removing waste in cells. If they are not functioning properly, waste builds up and can make cells sick.
Mr. Cell Situation: Mr. Cell is concerned that his cells are accumulating a lot of garbage and waste. He notices that the cells are not cleaning up the waste properly and are starting to get sick. Question: Which cellular organelle might be failing in Mr. Célula's cells, and how might this affect the health of the cells?
Cell membrane
Its primary role lies in regulating the passage of substances, including nutrients and waste materials.
Lysosome
They facilitate cellular digestion, by disposing of waste, recycling nutrients, and defending against pathogenic invasions.

Eukaryotic cells
Eukaryotic cells are cells which contains a nucleus enclosed within the nuclear membrane. Protozoa, fungi, plants, and animals are the few eukaryotic
Answer: Ribosomes are responsible for producing proteins, which are essential for many functions in cells, such as growth and repair. If ribosomes are not functioning well, cells cannot produce the proteins they need to be healthy.
Case Study 2:
The Adventure of the Little Ribosome Situation: The Little Ribosome is sad because it can't make proteins properly. Without the necessary proteins, the cells in his body are not functioning well and feel weak. Question: What is the main function of ribosomes in cells, and why is it important for the health of cells that ribosomes function well?
Answer: The nucleus controls all the activities of the cell and stores the genetic material. If the nucleus is disorganized, it cannot coordinate cell growth and division well, which can cause problems in cell function.
Case Study 3:
The Mystery of the Disorganized Nucleus. Situation: Mrs. Cell is concerned that the nucleus of her cells is disorganized and cannot control cellular activities well. The cells are not growing and dividing properly. Question: What is the function of the nucleus in a cell and how can the disorganization of the nucleus affect the functioning of the cell?
Answer: Mitochondria are known as the “power plants” of the cell because they convert nutrients into energy. If the mitochondria are not working well, the cells do not get enough energy to do their work, which can make a person feel tired and weak.
Case Study 4:
The Mitochondria Problem. Situation: Mr. Energy is tired because his cells are not producing enough energy. His mitochondria are failing and cannot convert food into energy properly. Question: What role do mitochondria have in cells? What happens when mitochondria cannot produce enough energy?
Mitochondria
Present in eukaryotic animal and plant cells. Their primary function is energy generation through cellular respiration (ATP production).
Prokaryotic
A prokaryote is a single-cell organism whose cell lacks a nucleus and other membrane-bound organelles.
Cytoplasm
It plays a crucial role in biochemical reactions, energy production, and substance transport. Essential for cellular metabolism, it provides structural support to the cell.
Golgy aparatus
The Golgi apparatus, which appears as a stack-like structure, is the organelle that prepares, modifies, and sorts proteins from the endoplasmic reticulum.
Cell nucleus An organelle that houses DNA, located in the center of eukaryotic cells. Its primary function is to store and safeguard genetic information, controlling gene expression and DNA replication.
