Approx. 45 POINTS

Photosynthesis, Cellular Respiration and Cell Biology EOC Standards

√
I can identify inputs and/or outputs of matter and/or energy in photosynthesis using words and/or chemical
formulas (i.e., inputs are carbon dioxide/CO2, water/H20, light energy; outputs include glucose/C6H12O6,
oxygen/O2).
I can describe the rearrangement of atoms during photosynthesis using the chemical equation for photosynthesis.
I can explain the role of photosynthesis in the life of plants (e.g., photosynthesis is the only source of glucose that
provides chemical energy or is incorporated into large molecules).
I can explain the role of photosynthesis in the life of animals (e.g., photosynthesis is the source of the chemical
energy animals require to live and grow; photosynthesis provides oxygen).
I can describe cellular respiration as the process cells use to change the energy of glucose into energy in the form
of ATP and/or the process that provides the energy source for most living organisms.
I can compare cellular respiration to the burning of fossil fuels (e.g., large carbon-containing compounds are
broken into smaller carbon compounds as chemical energy is transformed to different forms of energy in both
cellular respiration and combustion of fossil fuels).
I can describe the inputs and/or outputs of matter and/or energy in cellular respiration and/or in combustion (i.e.,
inputs include glucose or large carbohydrates and oxygen, outputs include carbon dioxide, water, and
energy/ATP).
I can describe the essential function(s) of structures within cells (i.e., cellular membrane, cell wall, nucleus,
chromosome, chloroplast, mitochondrion, ribosome, cytoplasm).
I can describe the essential function(s) of structures within cells (i.e., cellular membrane, cell wall, nucleus,
chromosome, chloroplast, mitochondrion, ribosome, cytoplasm).
STEP 1 - Reflect on the plant standards above, by marking a plus, check or minus to note your understanding.
STEP 2 - Identify vocab/concepts that are unclear. Review notes, worksheets, Blue Textbook pages 348-372. Visit
himsbio.pbworks.com and review ppt slides and readings that were used in class. Identify 4 vocab or concepts to define:
Word
Definition/Explanation
Picture/Diagram
_
STEP 3 - Select 5 of the following questions to answer on a separate piece of paper:
1.
2.
3.
4.
5.
6.
Explain how a leaf, stem and root work together to make a potato.
How much of a plant’s energy come from air? Sunlight? Water? Soil?
Now think of a plant’s biomass, how much of the matter came from air? Sunlight? Water? Soil?
Explain why a plant root cell does not have a chloroplast.
Identify what type molecules go in and out of a plant’s roots. Explain what process is going on.
Describe the process that energy containing molecules are assembled when glucose is broken down in
respiration.
7. Describe evidence that supports that plants build their biomass from the carbon dioxide from the air and
not the soil.
8. If plants do respiration all the time, why would CO2 concentrations in the air go down in the light?
9. Describe where plants get the atoms that make up their biomass, Carbon, Oxygen, Hydrogen and Nitrogen.
What molecules do they build to make biomass?
10. Explain the matter transfer in plants as it performs both photosynthesis and cellular respiration.
11. Explain the energy transfer in plants as it performs both photosynthesis and cellular respiration.
STEP 4 – Select 3 concepts or terms to compare and contrast. Explain how they are similar and they are
different:
a. Plant cells and animal cells
b. Cellular Respiration and Photosynthesis
c. Chloroplast and Mitochondria
d. Light energy and chemical potential energy
e. Molecules in soil minerals and molecules in air
f. Energy storage in a living plant and energy storage in a dead plant
g. Gas exchange in animals and gas exchange in plants
h. Gas exchange around a leaf cell and gas exchange around a root cell
STEP 5 – Select 2 examples to explain how matter is transferred and energy is transformed. Be sure to
answer the following questions in each example:
1. Movement question - where are atoms moving to and from?
2. Carbon question - what molecules are carbon in before and after the reaction
3. Energy question - what is the form and source of energy before and after the reaction
Examples:
a. How does a cell in a radish use food to move and function?
b. How does a radish leaf get food to a cell in its radish?
c. How does a cell in a radish use food to grow and divide?
d. How does a tree get food to a cell in its root?
e. How does a cell in a tree trunk use food to move and function?
f. How does a cell in the trunk of a tree use food to grow and divide?
