PAPERS SUMMARY OF CELL
Cell theory refers to
the idea that cells are the basic unit of structure in every living thing. The
observations of Hooke, Leeuwenhoek, Schleiden, Schwann, Virchow, and others led
to the development of the cell theory. The cell theory is a widely accepted
explanation of the relationship between cells and living things. The theory
says that new cells are formed from other existing cells, and that the cell is
a fundamental unit of structure, function and organization in all living
organisms.
Classical interpretation of the
theory:
1. 1.All
organisms are made up of one or more cells.
2. 2.Cells are the fundamental functional and structural unit
of life.
3. 3. All
cells come from pre-existing cells.
4. 4. The cell is the unit of structure, physiology, and
organization in living things.
5.
The cell retains a dual existence as a distinct entity
and a building block in the construction
of organisms.
Modern interpretation of the
theory:
1. The generally accepted parts of
modern cell theory include:
1. 2. The cell is the fundamental unit of structure and
function in living things.
2. 3. All cells come from pre-existing cells by division.
3. 4. Energy flow (metabolism and biochemistry) occurs within
cells.
4. 5. Cells contain hereditary information (DNA) which is
passed from cell to cell during
cell division.
5. 6. All cells are basically the same in chemical composition.
6. 7. All known living things are made up of cells.
7. 8. Some organisms are unicellular, i.e., made up of only one
cell.
8. 9. Others are multicellular, composed of a number of cells.
9. 10.The activity of an organism depends on the total activity
of independent cells
