Week 18 DCA Study Guide
Please remember this is a STUDY GUIDE, you should read/study your journals, graded papers, review power points on
the class website, read/study information in the online textbooks, and request tutoring if necessary. The DCA will be
on _Wednesday, January 16th.

Complete the following questions.
1.
What are the 3 main parts of The Cell Theory? 1) all living things are made of cells
2) all cells come form pre-existing cells, and 3) the cell is the basic complete unit of living things.
2.
Compare photosynthesis and cellular respiration – how are they alike? How are they different?
They are chemical reactions that take place in cells and involve the transformation of energy. Although they use the
same compounds the reactions are opposite from one another. Photosynthesis takes place in the cells of autotrophs,
cellular respiration occurs in the cells of autotrophs and and heterotrophs.
3.
Write out the chemical equation for Photosynthesis – label the products, reactants, describe the energy
transformation that takes place, name the organelle that it takes place in:
6CO2

Sunlight
Products
absorbed
Radiant energy from the sun is absorbed by the chlorophyll in chloroplasts of plant cells and transformed into
chemical energy called glucose (sugar).
4.
Write out the chemical equation for Cellular Respiration – label the products, reactants, describe the energy
transformation that takes place, name the organelle that it takes place in:
C6H12O6 + 6O2
>>>>
6CO2
Reactants
ATP (thermal energy) Products
+
6H2O
released
Chemical energy in the form of glucose (sugar) is transformed into ATP (thermal energy) in the mitochondrion of cells
5.
Describe trait – include a definition, an example, the name of the molecule that codes for a trait and where
the molecule is located in a cell.
Traits are characteristics of organisms such as hair color, skin tone etc. Traits can be inherited or acquired. Inherited
traits are passed down to offspring form parents and are coded for by genes. Genes are sections fo DNA that contain
information about an organism. DNA makes up the chromosomes (chromatin) which is found in the nucleus of
eukaryotic cells. Genetic material of prokaryotic cells is found in the cytoplasm.
THIS IS ONLY A STUDY GUIDE AND COVERS ONLY THE BASIC CONCEPTS, TO SUCCESSFULLY COMPLETE THE 18 wk DCA
YOU MUST BE ABLE TO APPLY THE CONCEPTS TO “REAL WORLD” EXAMPLES AND SITUATIONS.
