c) atoms of different elements can combine to form compounds
d) atoms are not made, destroyed, or changed in chemical reactions
e) the number and kinds of atoms remain the same in a compound
Add the 3 principles of the Cell Theory to your class notes
1. all organisms are composed of one or more cells 2. the cell is the basic unit of structure and organization in living organisms 3. all cells come from preexisting cells
(can be found in the video clip or the ppts slides or your textbook Chapter 3.1)
Use your textbook, Chapter 3.1, the ppt slides provided or the video to answer the following questions about Cell Theory.
We get the name for "cells" from a scientist named Hooke who thought cells
looked like the rooms ("cells") in monasteries.
Scientists first accepted that
A all plants were made of cells (Schleiden) before all animals were made of
B all animals were made of cells (Schwann) before all plants were made of cells
We give credit for the discovery of the microscope to
Who is given credit for the Cell Theory principle that "all existing cells are
produced by other living cells"?
A friend tells you he read somewhere that rotting garbage can turn into maggots,
which are fly larvae, and the maggots can then grow into adult flies. What part
of the cell theory could you use to refute (disprove) his claim?
B all existing cells are produced by other living cells
A all organisms are made of cells
C a cell is the most basic unit of life
The development of the cell theory is closely tied to the advancement in
technology of the microscope.
A difference between the Atomic Theory and the Cell Theory is...
A atomic theory defines basics of chemistry
B cell theory defines basics of biology
C A and B are both correct
Another difference between Atomic and Cell Theory is
B atomic theory is about inorganic matter, and cell theory is about living
A atomic theory is about living organisms, and cell theory is about inorganic
matter or nonliving organisms.
There are lots of similarities between Atomic and Cell Theory, including...
A both were developed over time by scientists.
B both are explanations of organic and inorganic matter.
C both came about through the advancement of the microscope.
D A, B, and C are correct
Both theories (atomic and cell) are important because...
A they apply to all inorganic and organic matter.
B they explain how single atoms/cells can create larger molecules or organisms.
C they prove that "nothing comes out of nothing".
D A, B, and C are true
