cell theory is a scientific theory which describes the properties of
cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
This discovery is largely attributed to Robert Hooke , and began the scientific study of cells, also known as cell biology.
The discovery of the cell was made possible through the invention of the microscope.
TENET OF CELL THEORY.
Tenet is one of the principles on which a belief or theory is based.
The three tenets to the cell theory are as described below:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells come from preexisting cells.
The modern version of the Cell. Theory includes the ideas that:
•Energy flow occurs within cells.
•Heredity information (DNA) is passed on from cell to cell.
•All cells have the same basic chemical composition.
Do You Know that Cells Commit Suicide?
When a cell becomes damaged or undergoes some type of infection, it will self destruct by a process called
apoptosis . Apoptosis works to ensure proper development and to keep the body’s natural process of mitosis in check. A cell’s inability to undergo apoptosis can result in the development of cancer .
TYPES OF CELLS.
Eukaryotic and prokaryotic cells are the two main types of cells. Eukaryotic cells are called so because they have a true
nucleus . Animals, plants, fungi and protists are examples of organisms that are composed of eukaryotic cells.
Prokaryotes include bacteria and
