i think it's because onions grow underground so chloroplasts are not needed to absorb sunlight.
Animal cells,prokariyotic cells,protozoans and fungi do not have.They are in plant and algal cells.
Onion cells are clear because they are underground and protected. Therefore they have no chlorophyll to give them any color.
In cooking, the onion would caramelize.
"calls" do not contain chloroplasts. However, if you mean cells, then any cell that undergoes photosynthesis has choloroplasts. This would include plant cells as well as some bacteria, archaebacteria, and protist cells.
Onions themselves are root bulbs, and so cannot photosynthesize. Keeping that in mind, onion leaves and the sprouting plant from the onion bulb CAN photosynthesize like all other leaved plants. Hope this helps! Daniel A
the differentiate between onion and hydrilla cells is hydrilla cells have chloroplasts while onion cells have not
still not yet sir
An ELODEA cell is a PLANT cell. A HUMAN EPIDERMAIL cell is an ANIMAL cell. if you know that plant cells and animal cells have different organelles, then you should be good to go.
its look like a tissue paper
Yes, sometimes there will be green portions of the onion. If you look at those cells under the microscope, you will see chloroplasts.
There arent any. There arent any. There arent any.
Onions are the root bulbs of onion plants. The plant itself contains chloroplasts, which cause the green colour, whereas the onion bulb itself contains other pigments and few, if any, chloroplasts.
