Cell theory Flashcards
What is the cell theory?
Is a fundamental concept in biology that explains the basic structure and function of living organisms.
It states that all living things are composed of cells, which are the basic unit of life.
What three components does the cell theory have?
- All living things are made up of cells.
- Cells are the basic unit of structure and function in living organisms.
- Cells come from pre-existing cells.
The first component of cell theory was proposed by who?
Robert Hooke in 1665, when he observed cells in a piece of cork under a microscope.
The second component of the cell theory was developed by who?
by Matthias Schleiden and Theodor Schwann in the 1830s when they observed that cells were the basic unit of plant and animal tissues.
The third component of the cell theory was proposed by who?
Was proposed by Rudolf Virchow in 1858, when he observed that all cells come from pre-existing cells.
What are stem cells?
Stem cells are undifferentiated cells that have the ability to differentiate into various cell types in the body.
What is the stem cells theory?
explains the importance of these cells in the development, growth, and repair of tissues in the body.
What are the stem cells ability?
to divide and differentiate into specialized cells, such as muscle cells, nerve cells, or blood cells. This ability makes them crucial for the development and maintenance of tissues and organs in the body.
What are the two main types of stem cells?
embryonic stem cells and adult stem cells.
