Which of the following changes will most likely increase the photosynthetic rate of a plant?

An increase in CO2 in the air

Using the diagram below, identify which letter represents the layer where most photosynthesis occurs

C

Photosynthesis takes place in the _______ of green plants.

Chloroplast

Photosynthesis and cellular respiration are two processes involved in energy transformations. Which statement describes the structure that captures energy and the molecule that stores the energy?

Chloroplast captures energy and glucose stores energy

In the above equation, substance X is most likely​​​​​​

Glucose

Bubbles forming in the test tube in the right side of the diagram (setup with light) are the direct result of which of the following processes?

Light dependent reactions

Which of the following is the correct transformation of energy that takes place from the start of photosynthesis to the end of photosynthesis?

Light energy → Chemical energy (glucose)

Which of the following statements is best supported by the energy pathway diagram above?

Organism A is a photosynthetic organism

Which of the following is the most appropriate conclusion that can be drawn from the data in the graph?

Red and blue lights result in the highest rates of photosynthesis

An organism was added to a test tube containing water, which was then sealed and placed in sunlight. The graph shows an increase in the oxygen content of the test tube over a period of time.

aquatic plant

In the 1660s, Flemish physician Jan van Helmont grew a small willow tree in a pot of soil. He added only water to the pot. At the end of five years, he found that the tree had gained 75 kilograms, but there was very little change in the mass of the soil. Van Helmont concluded that the plant gained weight directly from the water. We now know that this conclusion is incorrect because, in addition to water, photosynthesis also requires

carbon dioxide from the air

Which of the following best describes the flow of a carbon atom as it enters and moves through a plant as the plant undergoes photosynthesis.

stomata → mesophyll cell → phloem
