chloroplasts contain chlorophyll which help to make the food for the plant (glucose). An onion is a bulb, it is food storage for the actual onion plant, it doesn't make its own food so doesn't need chloroplasts
*Chloroplasts are used for photosynthesis (I) Hope it helps (Y)

∙ 13y ago- The onion parts above ground do.
- Most onions parts that we eat grow below ground and have no need for active chloroplasts as there is no light there. The germ tissue at the center of an onion certainly does though as when it is ready to sprout this tissue sends out green shoots with plenty of chloroplasts.

Which structure in an onion epidermal cell is semipermeable?
cell wall & cytoplasm
What cell contain the most chloroplast?
Plant Cell
What is the size of an epidermal onion cell?
The average epithelial Onion Cell is 30.2 to 35.4 micrometers in diameter. I just did this exercise in cell bio lab.
Why onion cells do not contain chloroplast?
Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors because it's fall?! Onions dont need chloroplasts, so they dont have them.
What causes the shape of a human cheek cell to be different from the shape of onion's epidermal cell?
plant cells have a cell wall - animal cells do not
Does an onion epidermal cell have depth?
yes
What is a epidermal cell?
it is a thin layer that can be peeled out from an onion.
Which structure in an onion epidermal cell is semipermeable?
cell wall & cytoplasm
How are onion cell and hydrilla cells alike?
the differentiate between onion and hydrilla cells is hydrilla cells have chloroplasts while onion cells have not
What part of the onion would have chloroplast?
All plant cells contain chloroplasts, the amount present depends on the function of the cell. for example leaves will contain loads of chloroplast, hence why they are green. The cells of an onion will still contain chloroplasts but only a few in comparison to the amount in a cell situated in the leaf. This is because onions are underground and aren't the primary site for photosynthesis.
Does an onion cell has chloroplast?
yes because all plant cell have it
Parts of an onion skin cell that you can not see?
the chloroplast
Does onion cell have chloroplast?
yes it can, if its a plant, then it has chloroplasts
What structure observe in onion epidermal cells are not present in human epithelial cells?
The structure of onion epidermal cells refers to the arrangement of tissues in this cells. You can find the structure of onion epidermal cells online athttp://biology.touchspin.com/onion_epidermis.php. The structures observed in an onion epidermal cell, which are not present in the human epithelial cells are cell wall, central vacuole and vacuolar membrane.
Is the chloroplast in onion cells larger than the nuclei?
Chloroplasts are larger than nuclei. A typical Chloroplast measure 4 to 6 um, and a typical nucleus measure about 3 um.
Why half of the onion epidermal cell is in darkness under the microscope?
becuse of the lodine solution
Does a animal cell contain a chloroplast?
no
