In this flow chart: Chlorophyll absorbs green wavelengths from the sun, making the plant look green.

1

In this flow chart: Excess sugar is stored as starch (food) in the roots.

1

In this flow chart: Water, CO2, and sunlight combine in the leaf to make sugar.

1

In this flow chart: Water is absorbed through the roots and carried through the stem to the rest of the plant. A plant's roots replace water lost during transpiration,

1

In this flow chart: Oxygen and water vapor exit the leaf through the stomata. Water loss from leaves is call transpiration.

What is the role of chlorophyll in photosynthesis?

It contributes to cellular respiration.

It generates oxygen only.

It absorbs sunlight to help convert CO2 into carbohydrates.

It produces carbon dioxide.

How do autotrophic organisms obtain their energy?

From converting light energy into chemical energy.

From breaking down dead matter

Directly from the sun's heat.

From consuming other organisms

What is the primary end product of photosynthesis, created from CO2 and sunlight?

Nucleic acids

Lipids

Proteins

Carbohydrates

Correctly order the processes which happens during the photosynthesis:

The water molecules are separating into Hydrogen and Oxygen
Conversion happens from light energy to chemical energy.
Chlorophyll absorbs the light energy
Carbon dioxide is reduced into carbohydrates.

Simulator Procedure
Click on the KOH bottle to open the lid.
Drag and drop the KOH solution towards the boiling tube to fill the KOH solution into the boiling tube.
Now drag and place the laboratory stand near the plant. Click the boiling tube to insert the plant leaf.
Drag and drop the split cork towards the boiling tube.
Click on the petroleum jelly bottle cap.
Drag and drop the spatula towards the petroleum jelly to take the petroleum jelly and apply it over the split cork.
Click on the Next button.
Drag and drop the beaker containing 150 ml water towards the tripod stand.
Drag and drop the lighter towards the spirit lamp and lid the spirit lamp.
Click on the boiling tube to remove the setup and drag and drop the leaf into the beaker to boil it for some time(10 to 15 mins).
Turn off the spirit lamp.
Click on the alcohol bottle cap to open the lid.
Drag and drop the alcohol towards the empty boiling tube and fill the alcohol into it.
Drag and drop the forceps with the leaf toward the boiling tube containing alcohol.
Drag and drop the test tube holder to take the boiling tube.
Drag and drop the boiling tube with the test tube holder into the beaker.
Check out the temperature of the water range between 60 – 70°C by, drag and dropping the thermometer into the water.
Drag and drop the iodine solution bottle and the solution into the petri dish.
Take out the leaf from the boiling tube containing alcohol using forceps.
Drag and drop the forceps with the leaf into the petri dish containing water.
Drag and drop the leaf from the water-containing petri dish and dip it into the iodine solution.
Click on the Inference button.
Click on the Reset button to do the experiment again.
