Photosynthesis & Cellular Respiration Quiz

What is photosynthesis?

• Photosynthesis is a process in which sunlight energy is used to make glucose.

• Photosynthesis is a process in which animals convert food into energy.

• Photosynthesis is a process in which plants absorb water from the soil only.

• Photosynthesis is a process in which plants release oxygen by breathing.

What are the two main functions of chloroplasts?

• The two main functions of chloroplasts are to produce food (glucose) during photosynthesis and to store food energy.

• To control cell division and store genetic information.

• To break down waste materials and recycle cellular components.

• To transport water and minerals throughout the plant.

Why does most leaves appear green?

• Leaves appear green because chlorophyll absorbs most colors in the color spectrum and reflects only green and yellow wavelengths of light.

• Leaves appear green because they contain a pigment that reflects only red light.

• Leaves appear green because they do not contain any pigments.

• Leaves appear green because they absorb only green light.

What is the primary pigment found in the chloroplast?

• Chlorophyll

• Carotene

• Xanthophyll

• Anthocyanin
