Photosynthesis- Basic Chemistry Test Review

Vocabulary: Quizlet Flashcards:

Guided Questions:

1. What is the difference between protons and electrons?

2. Which element is shown to the right?

3. How many more electrons does the atom to the right need in its

outermost shell?

4. Practice drawing Lewis & Bohr models for the following elements:

Element

Bohr Model

Lewis Dot Model

5. Practice drawing the bonding between oxygen gas (O2) and (H20), using Lewis dot models. What are their

roles in photosynthesis?

6. Write out the formula for Photosynthesis and briefly state where each compound comes from (if a reactant)

and where each goes (if it¡¯s a product).

7. What three factors may influence the rate of photosynthesis, and how?

8. Fill-in the chart showing the light-dependent and light-independent reactions. Add as many details as you

can from the word bank. Light reaction, ADP + P, Calvin cycle, NADPH, Light, NADP+, Granum, Dead

batteries, Radiant energy, Thylakoid, Chemical energy, O2, H2O, ATP, CO2, C6H12O6, Stroma

9. Reduce, Reuse Recycle. How does this apply in photosynthesis? Think of the compounds that are given off

by one organism, and used by another, and vice versa.

10. Trace hydrogen through the steps of photosynthesis. Where does it finally end up?

11. What is the role of Nitrogen in plants?

12. What is the function of stomata? Which gases enter the leaf/exit, and why?

12. Under which conditions would stomata open? Close?

14. Label the diagram

of the microscope to

the right using the

word bank.

15. Fill-in the chart to calculate Magnification of lenses.

Applications: How would the Stomata & Leaf Disk labs data vary with the following species?

Type of plant

Stomata Lab

1. # of stomata (average, high,

low)

2. Surface (upper, lower)

Water Lily

1.

2.

Good amount of sunlight, nutrient-rich

water, high CO2.

Venus Fly Trap

1.

2.

Good amount of sunlight, good amount

of water, nutrient-poor soil

Cactus

1.

2.

Grows in Death Valley outside of Los

Angeles (high sun, high CO2, low amount

of water)

Leaf Disk Lab

Rate of Photosynthesis

(average, high, low)
