How do cells differentiate and become specialized?
Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.
What is the difference between differentiation and Specialisation?
Differentiated cells are important in a multicellular organism because they are able to perform a specialised function in the body. However, specialisation comes at a cost. The cost is that the differentiated cells often lose the ability to make new copies of themselves.
How many specialized cell types are there in the digestive system?
Four different types of cells make up the gastric glands: Mucous cells. Parietal cells. Chief cells.
What cells form enzymes and acids in the stomach?
Chief cells, also found within the gastric pits of the stomach, produce two digestive enzymes: pepsinogen and gastric lipase.
What mechanical and chemical digestion occurs in the stomach?
In the stomach, food undergoes chemical and mechanical digestion. Here, peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion).
What is a specialized cell?
Specialised cells are cells designed to carry out a particular role in the body, such as red blood cells which are designed to carry oxygen. Nerve cells help contraction of muscles or the relaxation of muscles according to what specific job you need them to do.
What are examples of specialized cells?
Specialized Cells in the Body
- Neurons. Neurons are specialized cells that carry messages within the human brain.
- Muscle Cells. Muscle cells make movement possible.
- Sperm Cells. Specialized sperm cells are necessary for human reproduction.
- Red Blood Cells.
- Leukocyte.
What is an example of cell specialization?
What is cell specialization give one example? Blood cells are an example of specialization within a system of the body and include red blood cells, white blood cells, and platelets. Red blood cells, for instance, specialize in carrying oxygen throughout the body.

Which type of cells are found in gastric glands?
The intermediate gastric glands produce most of the digestive substances secreted by the stomach. These glands are narrow tubules composed of three major cell types: zymogenic, parietal, and mucous neck cells.
