Use the diagram above to answer the question that follows The experiment is set up to determine the presence of

Chlorophyll: Experiments related to chlorophyll typically involve leaves and light exposure to understand photosynthesis. You might see diagrams showing a leaf that is partially covered with foil to demonstrate which parts of the leaf perform photosynthesis.

Starch: To test for the presence of starch, particularly in plants, an experiment usually involves boiling a leaf in water, then in alcohol, and finally treating it with iodine solution. The presence of starch is confirmed by a blue-black color change.

Oxygen: Experiments designed to detect oxygen often involve aquatic plants like Elodea. When the plant is exposed to light, bubbles or gases released would indicate photosynthetic activity, releasing oxygen.

Pigment: Pigment experiments often relate to chromatography, where pigments are separated on a medium like paper. These are used to study various pigments present within plant tissues.
