Summary Introduction
To review:
The mechanism by which the fireflies capture the energy from the environment to be utilized in the generation of light.
Introduction:
The fireflies (Photuris pennsylvanica) are known to produce light, which is a form of mating signal to attract mates of the opposite sex. This phenomenon is known as bioluminescence in which the fireflies capture the energy from the environment and transform into light energy. The light is emitted from an organ located in their abdomen known as the firefly lantern.

- An experiment was done to determine how color of light and distance affects photosynthetic activity of the pond weed. Pond weed was placed in a test tube containing a solution of sodium hydrogen carbonate, and had its end cut; light was placed 50 cm away and four colors were tested (clear, red, blue, and green). After placing the light, the pondweed was given a certain amount of time to adjust before counting the bubbles, bubbles were counted for 1, 3, and 5 minutes. Only the bubbles that came out of the cut end was counted to represent the rate of photosynthesis. Below is the tabulated results. What are the possible factors or errors that could have affected clear/white light to have lower photosynthetic activity? In theory this should have the highest rate.arrow_forwardWhich of the following best describes the products of the photochemical reactions of photosynthesis?A) NADH and ATP are made in the stromaB) NADPH and ATP are made in the stromaC) NADH and ATP are made in the thylakoid lumenD) NADPH is made in the stroma and ATP is made in the thylakoid lumenE) NADPH and ATP are made in the thylakoid lumenarrow_forwardProvide two reasons why it is not possible for the Calvin cycle to efficiently operate in the dark.arrow_forward

They place an Elodea plant into a large test tube with water and assemble a volumeter using a cork and calibrated glass tubing. Then, the apparatus is placed near a lamp. Soon after, the water level in the tubing begins to move upward. Why does the edge of the water move upward?arrow_forwardDiscuss in detail photorespiration in plants.arrow_forward
