100

This organelle controls what enters and leaves the cell.

What is the cell membrane?

100

The main purpose of photosynthesis is to convert sunlight into this sugar.

What is glucose?

100

This organelle captures sunlight and carries out photosynthesis.

What is the chloroplast?

100

Gas exchange in plants occurs through these tiny openings.

 What are stomata?

100

If the cell membrane stopped working, the cell would lose this ability.

What is the ability to control what enters and exits?

200

This organelle contains DNA and controls the cell’s activities.

What is the nucleus?

200

These are the two main reactants of photosynthesis (not including sunlight).

What are carbon dioxide and water?

200

This green pigment absorbs light energy.

What is chlorophyll?

200

The singular form of stomata is this.

What is a stoma?

200

This organelle is found in plant cells but not animal cells and provides structure.

 What is the cell wall?

300

This organelle is known as the “powerhouse of the cell.”

What is the mitochondria?

300

These are the two products of photosynthesis.

What are glucose and oxygen?

300

These flattened membrane sacs inside the chloroplast contain chlorophyll.

What are thylakoids?

300

These 3 organisms perform photosynthesis.


👉 What are plants, algae and cyanobacteria?

300

Without chlorophyll, a plant would not be able to do this process.

What is photosynthesis?

400

This organelle assembles amino acids to create proteins.

What are ribosomes?

400

This is the chemical formula for glucose.

What is C₆H₁₂O₆?

400

A stack of thylakoids is called this.

What is a granum?

400

Scientists estimate that photosynthetic organisms (plants, algae, and cyanobacteria) produce approximately this percentage of Earth’s oxygen. 

What is between 50–70% of Earth’s oxygen?

400

In photosynthesis, carbon dioxide and water are classified as these.

What are reactants?

500

This organelle uses chemicals to break down food and worn-out cell parts.

What are lysosomes?

500

This is the full balanced equation for photosynthesis.

What is 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂?

500

Plants look green because they absorb these two colors of light.

What is blue and red light?

500

This animal is one of a few that can perform photosynthesis

What are Phytoplankton

500

If all of a plant’s stomata suddenly closed on a sunny day, photosynthesis would quickly decrease for this reason.

What is: Carbon dioxide could not enter the leaf, so the plant could not complete photosynthesis?
