Question

onions grow underground. therefore, onion bulb cells b. choices: reset do not have chloroplasts because they are a bulb, and not a seed, which is where chloroplasts are found. store nutrients and do not perform photosynthesis, therefore do not need chloroplasts lose their chloroplasts once they are harvested and exposed to light do not require energy, so they have no chloroplasts

Explanation:

Onion bulbs grow underground and function as nutrient storage structures. Since they are not exposed to light, they do not perform photosynthesis. Chloroplasts are organelles required for photosynthesis, so these cells do not need them. The other options are incorrect: chloroplasts are found in photosynthetic leaf cells (not seeds), harvested onions exposed to light can develop chloroplasts in some cells, and all cells need energy (they use mitochondria for this, not chloroplasts).

Answer:

store nutrients and do not perform photosynthesis, therefore do not need chloroplasts
