Foundations of Chemisty in Biology
Describe an example of a
chemical reaction that
occurs in the body.
One of the many chemical reactions that happen within the body is
Respiration. Respiration is the prosses of glucose reacting with
oxygene to create energy. In the cell's Mitochrongria glucose
oxidation creates ATP, the cell then uses that ATP for its cellular
Describe the primary
structures in plant cells.
Cell Wall- is the protective layer outside the Plasma membrane,
composed largely of cellulose.
Central Vacuole- Large storage compartment for the cell.
Plastids- Groups of closely bound organelles.
Nucleus- Membrane bound structure which contains the hereditary
material of the cell
Mitochondria- Provides a site for cellular respiration
Cell Membrane- Inside of the cell wall in plants encloses cytoplasm,
Explain the role of each
structure in plant cells.
Cell Wall- Provides structural support and protection. It also expands
to hold the water in the cell without bursting.
Central vacuole- Stores water and proteins. It also maintains turgor
pressure agent the cell wall.
Plastids- They are responsible for photosynthesis
Nucleus- The main control room of the cell. Directs all activates
within the cell.
Mitochondria- Power plants. Convert glucose to ATP.
Cell Membrane- Only allows certain substances to pass through,
The process in which plant cells create their energy is called
photosynthesis. Plants also use cellular respiration. The plant's
chloroplasts absorb the suns energy. The chloroplasts then use the
energy to turn stored water, and carbon dioxide into sugars. The
