BSC 108: Exam #2 Questions with Detailed Verified
Answers
What is photosynthetic autotroph? Ans: ✓ ✓ ✓ Creatures that generate their own organic matter
through photosynthesis.
What is the fluid inside chloroplasts called? Ans: ✓ ✓ ✓ Stroma.
What are the membranes inside chloroplasts called? Ans: ✓ ✓ ✓ Thykaloids.
What is the overall equation for photosynthesis? Ans: ✓ ✓ ✓ 6 CO2 + 6 H20 + Light Energy =
C6H12O6 + 6 O2
What is the primary function of pigments in photosynthesis? Ans: ✓ ✓ ✓ They hold electrons that
gain energy, which is then released and used.
What is the primary pigment used in photosynthesis? Ans: ✓ ✓ ✓ Chlorophyll A.
Why are leaves green? Ans: ✓ ✓ ✓ Green is the only color not absorbed during photosynthesis.
How and where does water enter a plant? Ans: ✓ ✓ ✓ Water enters hairs on the plant's roots
through osmosis.

How and where does carbon dioxide enter a plant? Ans: ✓ ✓ ✓ Carbon dioxide enters plants
through small holes on their leaves, called stoma.
The light reactions take place in three stages. Name the stages and summarize the events of each
stage. Ans: ✓ ✓ ✓ Absorption of Light, where sunlight is taken in by the plant through
chlorophylls; Electron Transport, where electrons travel in the thylakoid membrane to transport the
sunlight energy for conversion; and Generation of ATP, where the sunlight energy is converted into
energy for the plant.
What are all the products of the light reactions? Ans: ✓ ✓ ✓ ATP, NADPH, and oxygen.
The Calvin Cycle has three main stages. Name the stages and summarize the events of each stage.
Ans: ✓ ✓ ✓ Carbon Fixation, where plants attach carbon dioxide to a chemical to start
photosynthesis; Reduction Phase, where energy reacts with chemicals to create simple sugars; and
Carbohydrate Formation, where carbohydrates are produced.
What are all the produces in the Calvin cycle? Ans: ✓ ✓ ✓ Glucose, ADP, P, and NADP+.
Give two examples of plants that use C4 photosynthesis. Ans: ✓ ✓ ✓ Corn and Sugar Cane.
What environmental factor is C4 photosynthesis an adaptation for? Ans: ✓ ✓ ✓ Plants in hot, dry
areas.
Contrast carbon fixation in C4 and CAM plants. Ans: ✓ ✓ ✓ C4 plants separate carbon fixation from
the Calvin cycle spatially, whereas CAM plants do so using time.
What is Aerobic Respiration? Ans: ✓ ✓ ✓ When enough oxygen reaches cells to support energy
needs.
What is Anaerobic Respiration? Ans: ✓ ✓ ✓ When the demand for oxygen outstrips the body's
ability to deliver it.
