The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. The vacuole is prominent and present at the center of the cell, surrounded by cytoplasm.Click to see full answer. In respect to this, do onion cells have chloroplasts?Onion cells do not have chloroplasts becausethe onion is underground (where there is nolight). Without light, chloroplasts have no purpose. The green leaves and stem of an onion plantare normally exposed to daylight and so havechloroplasts, but the onion does not.Furthermore, why do some plant cells not contain chloroplasts? The inner stem cells and underground organs, such as the root system or bulb, contain no chloroplasts. Because no sunlight reaches these areas, chloroplasts would be useless. Fruit and flower cells typically do not contain chloroplasts because their primary jobs are reproduction and dispersal. Similarly, you may ask, why can’t you see chloroplasts in an onion cell? Most of the cell parts (called organelles) are almost invisible because they are colorless. We also looked at the cells of an onion bulb. Since the onion bulb grows underground, it doesn’t see any sunlight and so it doesn’t have any chloroplasts for photosynthesis.Why are there no chloroplasts in potato cells?Chloroplasts in potatoes. Tubers do not normally have chloroplasts, they have amyloplasts (colourless, starch-storing plastids) instead, and these will stay as amyloplasts all the while the tuber is in the dark (ie its normal condition, usually under the ground).
