Photosynthesis & Cellular Respiration

Which of the following is NOT a product of photosynthesis?

• Oxygen

• Glucose

• Carbon dioxide

• Water

Answer explanation

Carbon dioxide is not a product of photosynthesis. Photosynthesis produces oxygen, glucose, and water.

ATP has three molecules of phosphate, which means it has one more than ADP. This means it is a FULL battery! Why do we need a full battery to perform photosynthesis and cellular respiration?

• To release stored energy needed to power these processes.

• To store more carbon dioxide for photosynthesis.

• To make more oxygen for cellular respiration.

• To increase the number of cells in the organism.

In which part of a plant does photosynthesis primarily occur?

• Leaves

• Roots

• Stem

• Flowers

Answer explanation

Photosynthesis primarily occurs in the leaves of a plant. Leaves contain chlorophyll, which is essential for capturing sunlight and converting it into energy through photosynthesis.

Which of the following is the correct chemical equation for photosynthesis?

• CO2 + H2O -> C6H12O6 + O2

• C6H12O6 + O2 -> CO2 + H2O

• O2 + H2O -> CO2 + C6H12O6

• H2O + CO2 -> O2 + C6H12O6

Answer explanation

The correct chemical equation for photosynthesis is CO2 + H2O -> C6H12O6 + O2. This equation represents the conversion of carbon dioxide and water into glucose and oxygen through the process of photosynthesis.

Which organelle is responsible for photosynthesis in plant cells?

• Chloroplasts

• Mitochondria

• Nucleus

• Endoplasmic reticulum

Answer explanation

Chloroplasts are responsible for photosynthesis in plant cells. They contain chlorophyll, which captures sunlight and converts it into energy. Other organelles like mitochondria, nucleus, and endoplasmic reticulum do not have this function.

Where does cellular respiration primarily occur in cells?

• Mitochondria

• Nucleus

• Chloroplasts

• Endoplasmic reticulum

Answer explanation

Cellular respiration primarily occurs in the mitochondria, where energy is produced through the breakdown of glucose. The mitochondria is the powerhouse of the cell.
