All About CellsTEKS 7.12F recognize that
according to the cell theory all organisms are composed of cells & cells carry on similar functions such as extracting energy from food to sustain life
TEKS 7.3D relate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content
What do all of the
following objects have in common?
They are all living things so they are all made of
cells…
The Discovery of Cells
1665 – Robert Hooke is the first person to
describe & name cells by looking at cork. This is
what he saw.
1673 – Anton van Leeuwenhoek is credited with inventing the first microscope. He was the first person to observe microorganisms & single cells
1833 – Robert Brown
reported the
discovery of the
nucleus.
1838 – Theodor Schwann, who studied animal
cells, & Matthias
Schleiden, who studied plant cells,
came up with the original cell theory.
1858 – Rudolf
Virchow showed
new cells came from the division of old cells.
• All living things are made up of cells.
• The cell is the basic unit of structure & function in all living things.• All cells come from other living cells by division.
• Cells contain genetic information (DNA) that is passed from one cell to another.• All energy flow (metabolism) of life occurs within cells.
Cells are
alive.
Cells in multi-cellular organisms have different structures, or parts, that are specialized to do certain functions or jobs.
All cells work together to help the organism function as a whole.
The characteristics & needs of an
organism are in reality the
characteristics & needs of the cells that make up the
organism.
For example, you need
water because
your cells need
water.
Major cell functions: •extracting
energy from food by using water & gases
•reproducing through cell
division in order to grow & repair cells
•responding & adapting to
changes in the environment
•fighting disease & infection
•excreting wastes
