Photosynthesis, Respiration, and the Cell Cycle

What happens during photosynthesis?

• The cell uses oxygen to make food.

• The cell uses energy in sunlight to make food.

• The cell uses glucose to make oxygen.

• The cell uses energy in sunlight to make carbon dioxide.

What happens during respiration?

• Oxygen is released into the air.

• Glucose is broken down, releasing energy.

• Carbohydrates are released into the bloodstream.

What happens during metaphase?

• The cell grows and duplicates organelles.

• Chromosomes line up down the middle of the cell.

• Chromosomes get torn apart.

• A cell plate forms in the middle of the cell.

• Interphase

• Cytokinesis

• Prophase

• Mitosis
