UNIT 3: Cell Processes
The Big Picture…
Materials enter the cell by means of passive and active transport. Cells require energy, which they
manufacture and release in the processes of photosynthesis and respiration, and grow and reproduce
in a sequence called the cell cycle.
1. How do the cell processes contribute to homeostasis?
2. Why are photosynthesis and respiration a perfect match?
Prerequisite Knowledge…You should be able to:
Cells attempt to maintain homeostasis (balance between their internal environment and their external
environment.). They always try to work toward this equilibrium state.

By the conclusion of this unit, you should know the following:
_____1. Diffusion is the movement of molecules from where they are highly concentrated to
where they are less concentrated.
_____2. Osmosis (a special type of diffusion) is the movement of water from where it is highly
concentrated to where it is less concentrated, across a cell membrane.
_____3. Active transport requires the cell to use its own energy, while passive transport does
not require the use of energy.
_____4. During photosynthesis, plants and some other organisms use energy from the sun to
convert carbon dioxide and water into oxygen and glucose.
_____5. During respiration, cells break down simple food molecules such as sugar (glucose)
and create energy for the cell (ATP).
_____6. Fermentation is a process of obtaining cellular energy without oxygen present.
_____7. Before a cell divides, it copies its DNA so each new cell gets a copy of the genetic
material.
_____8. The stages of the cell cycle include: Interphase, Mitosis, and Cytokinesis.
By the conclusion of this unit, you should be able to do the following:
_____1. Predict the direction of molecule movement based concentration of substances inside
and outside the cells (osmosis and diffusion).
_____2. Use data to explain movement of particles during a lab.
_____3. Identify the formulas for cell respiration and photosynthesis.
_____4. Be able to explain how photosynthesis and cell respiration are related processes (how
they form a cycle).
_____5. Identify why cell division occurs.
_____6. Describe what happens during each stage of the cell cycle and identify differences
between plant and animal cells.
