Daily TAKS Connection:
Cellular Processes
BIO(4): The student knows that cells are the basic structures of all
living things and have specialized parts that perform specific
functions, and that viruses are different from cells and have
different properties and functions. The student is expected to:
(B) Investigate and identify cellular processes including
homeostasis, permeability, energy production, transportation
of molecules, disposal of wastes, function of cellular parts,
and synthesis of new molecules.
Day 1

Materials:




Foldable handout
Scissors
Pen
Colored
pencils/crayons

Cut each paper
hamburger fold. You
should have 4 ½
pieces of paper.
Staple all sheets
together
Cut on dotted line at
the top of each page
so that you form
“tabs” for each page.
Day 2 notes
Record the following notes on each
respective page
Cell Parts
 Nucleus- control center of the cell
 Mitochondria- Energy conversion; ATP;
numerous in muscle cells
 Chloroplast- site of photosynthesis contain
green pigment called chlorophyll to trap
sunlight
 Ribosome- site of protein synthesis
 Cell wall- only in plant cells; structure
 Cell membrane- transport of into/out of cell
 Flagella & Cilia- movement of the cell
Day 3 notes
Record the following notes on each
respective page
Cell Energy
Depletion of oxygen
results in production
of lactic acid build-up
(sore muscles)
Day 4 notes
Record the following notes on each
respective page
Cell Transport
Osmosis is the diffusion of water across a
semi-permeable membrane called the
lipid bilayer or cell membrane

Day 5 notes
Record the following notes on each
respective page
Homeostasis
 If a cell becomes to large to carry out
homeostasis, it divides into 2 identical
cells (binary fission)
 Dynamic Equilibrium is reached when
concentrations are equal on both sides
of the concentration gradient.
