Explanation:

1. For Question 17: Photosynthesis is the process by which plants use carbon - dioxide and water, in the presence of sunlight, to produce glucose and oxygen. Cellular respiration is the process by which cells break down glucose to produce energy, using oxygen and releasing carbon - dioxide.
2. For Question 18: Aerobic cellular respiration occurs in the mitochondria of eukaryotic cells. Chloroplasts are involved in photosynthesis, lysosomes are for waste - breakdown, and the nucleus contains genetic material.
