The following diagram demonstrates a physiological process taking place in green plants (a funnel and test tube inverted over Hydrilla in a beaker of water). The whole set up was placed in bright sunlight for several hours. Study the diagram and answer the questions that follow: The following diagram demonstrates a physiological process taking place in green plants (a funnel and test tube inverted over Hydrilla in a beaker of water). The whole set up was placed in bright sunlight for several hours. Study the diagram and answer the questions that follow:
What aspect of the physiological process is being examined?
Topic: Release of oxygen in photosynthesis
Answer
The RELEASE OF OXYGEN during PHOTOSYNTHESIS.
The apparatus identifies the aspect: the funnel and inverted test tube exist to COLLECT A GAS given off by the plant. Nothing else in the set-up would need them.
THE TEST that proves the gas is oxygen, and it should be written beside your answer: introduce a GLOWING SPLINT into the collected gas — it RELIGHTS, since oxygen supports combustion.
THE METHOD for every photosynthesis experiment — ask what the apparatus is designed to do: funnel and test tube over HYDRILLA — collects the OXYGEN released KOH in a flask — removes CARBON DIOXIDE BLACK PAPER over part of a leaf — removes LIGHT a VARIEGATED leaf — removes CHLOROPHYLL from part of it
