9. Chloroplast
10. DNA
Explanation:
7. plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
8. The nucleus contains DNA, which carries the genetic information to make the protein machines of a cell. However, the nucleus also contains something called the nucleolus, which is the largest structure in the cell nucleus. Like chromosomes, the nucleolus contains genetic information.
9. In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules. In plants, the products include a low-molecular-weight sugar (usually sucrose) that is exported to meet the metabolic needs of the many nonphotosynthetic cells of the organism.
