How do Plants Get Their Food

How do plants get their food?

• From the soil

• Combining carbon dioxide from air and water from soil

• Combining oxygen from the air and water vapour from the air

• Combining water from the air and carbon dioxide from the soil

Plants make their food by photosynthesis. What does the 'photo' refer to?

• The process requires water

• The process happens in the day

• The process requires light

• The process happens at night

During photosynthesis plants take carbon dioxide and water to make a sugar called glucose. What is the chemical formula of glucose?

• C₆H₁₂O₆

• C₆H₁₂O₁₂

• C₁₂H₁₂O₆

• C₁₂H₆O₁₂

What is the correct chemical equation for photosynthesis?

• 6CO₂ + H₂O -> C₆H₁₂O₆ + 6O₂

• CO₂ + H₂O -> C₆H₁₂O₆ + O₂

• 12CO₂ + 12H₂O -> C₆H₁₂O₆ + 12O₂

• 6CO₂ + 6H₂O -> C₆H₁₂O₆ + 6O₂

Energy is required for photosynthesis (Remember though its not in the equation as it is not a physical substance!) - where do plants get their energy?

• Sunlight

• The soil

• Water in the soil

• From the air

Which part of the plant absorbs sunlight?

• Mitochondria

• Vacuole

• Chloroplasts

• Cell wall

What is the substance found inside the organelle that absorbs light?

• Cytoplasm

• Chlorophyll

• Cell sap

• Plasma

In which cells does the most photosynthesis occur?

• Stomata

• Spongy Mesophyll Cells

• Guard cells

• Palisade Mesophyll Cells

Glucose is an example of what?

• Protein

• Carbohydrate

• Lipid

Organisms can take one carbohydrate and turn it into another. When plants make glucose during photosynthesis, what do they turn it into to store it?

• Starch

• Lipids

• Sucrose

• Keratin
