Introduction

Since the formation of classical cell theory, technology has improved, allowing for more detailed observations that have led to new discoveries about cells. These findings led to the formation of the modern cell theory, which has three main additions. First, that DNA is passed between cells during cell division. Second, that the cells of all organisms within a similar species are mostly the same. Finally, that energy flow occurs within cells.

Task

There are over 200 different cell types in the human body. Each type of cells is specialised to carry out a particular function, either solely, but usually by  forming a particular tissue. Different tissues then combine and form specific organs, where the organ is like a factory where every type of cell has its own job.

Process

1.Hormones and proteins that protect and repair brain cells and stimulate neural growth also decline with age. Older people often experience decreased blood flow to the brain, which can impair memory and lead to changes in cognitive skills.



2. Mature fat cells helped mice recover from spinal cord injuries, according to a promising new study. They could become a source for cell replacement therapy to treat central nervous system disorders in humans.



3. The DNA replication process, which takes place every time a cell divides, also triggers repair of DNA damage. Proteins are very similar to those of human cells. Researchers results can be used to develop more effective treatments for cancer in the long run.

4.Schwann cells, a special type of cells are capable of generating protective myelin sheath covers for the nerves at rates higher than earlier believed.

5. The stomach is a fascinating organ that has received short shrift through much of history. In medical writings during the Renaissance, the stomach was depicted as an inert bag in which food would collect, putrefying. The concept of active digestion by secretions from the stomach lining was unknown.

Conclusion

Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.
