Knowledge and Skills
Students will:
•
Apply the cell theory: the cell is the
basic unit of life and comes from
preexisting cells.
•
Explain mitosis, meiosis, and
differentiation, and how they relate to
growth in a multi-cellular organism.
Coloma Resources:
Glenco Biology – Section 6.3 & Chapter 9
Enzyme Lab pg. 164
Other Resources:
•
•
•
Explain that respiration provides
energy for making cell components.
•
•
Describe how the chemical
composition of cells originates from
•
outside the cell, such as the products
of digested food, and are used as the
building blocks by the cell to synthesize •
more complex chemicals.
Show how growth of multi-cellular
organisms is the result of an increase
in the number of cells, not just a
change in their size.

Apply an understanding of cells to the functioning of multicellular organisms including how
cells grow, develop and reproduce
Although most cells are too small to see with the unaided eye, learning about these units of life is
central to our understanding of all organisms. It is through the study of cells that biologists have come to
understand and interpret the unity that underlies the great diversity of living things. Biologists sometimes
express their understanding of this unity in terms of the Cell Theory: 1) all organisms are composed of
cells; 2) all cells arise from preexisting cells; and 3) the cell is the basic living unit of organization of all
organisms.
Of these three principles, currently in the summer of 2001, none are assigned to the elementary level
articulation of the Michigan Curriculum Framework Science Standards and Benchmarks. In middle
school the benchmarks address the concept that all organisms are composed of cells and that cells are
the basic living unit of organization. With the use of tools such as the hand lens and microscope,
common living things can be found to be made up of cells. It becomes increasingly important for the
explanation of why and how selected specialized cells are needed by plants and animals since students
often think incorrectly that there are only those two types of cells….plant and animal. The specialization
of functions that cells perform will dictate their actual form....i.e. comparison of a red blood cell to a
striated muscle cell.
In high school, students have difficulty discriminating between cell division, growth/enlargement, and
differentiation. Living things do not simply get larger due to cells growing larger. Growth of the organism
is the result of cell division and resulting increase of number of cells. The actual trigger for cell division
is the ratio of surface area of the cell to volume but total growth of the organism is not due to just bigger
sized cells.
Specialized cells and organelles carry out life functions and can be tied to actual classification of
organisms by cell type. Scientifically literate high school students will be able to reason that cells
specialize in order to efficiently divide or share the function needed to keep the organism alive. The
differences in cell type form basic divisions in the way scientists classify living things.
