Chapter 7: Cell Flashcards
Describe the three points of the cell theory?
All living things are made of cells
Cells are the basic units of cells
All cells come from all pre-existing cells
Which scientist(s) were responsible for the development of each point?
Robert Hooke: 1st to see and name cells (1665) Viewing cork under the microscope
Van Leeuwenhoek: 1st to see living (moving) cells (1674) Viewing pond water under microscope
Theodor Schwann: Stated “all plants are made of cells (1839)
Rudolph Virchow: Stated “all cells from pre-existing cells”

What happens to a cell in hypotonic solution (Animal)?
Cell Swells up and could possibly burst
What happens to a cell in hypertonic solution (Animal)?
Cell shrinks
What happens to a cell in isotonic solution (Animal)?
It stays the same
What happens to a cell in hypotonic solution (Plant)?
it will swell up and push against the cell wall
What happens to a cell in hypertonic solution (Plant)?
Cell Shrinks, but the cell wall stays the same
What happens to a cell in isotonic solution (Plant)?
Stays the same
Some Key ideas 7-1
The cell theory states the following:
All living things are composed of cells.
Cells are the basic unites of structure and function in living things.
New cells are produced by existing cells.
Cell theory states that cells are the basic units of all living things.
Biologists divide cells into 2 categories: prokaryotes and eukaryotes. The cells of eukaryotes have a nucleus while the prokaryotes do not.
