Why are chloroplasts not ordinarily visible in an unstained onion cell?

1. Because the chloroplasts that actually photosynthesize are found in the tops of the onions - the part that is actually above ground. There's no reason for there to be chlorophyll in the onion skin itself because these grow underground

∙ 14y agothere is no such thing as that. my email is darcel1995@ymail.com email me if you have more questions

∙ 11y agoBecause vacuoles having the same white color of the cytoplasm in such cells are difficult to differentiate.

∙ 13y agothe part we call the onion is the bulb which is in the ground and therefore cannot conduct photosynthesis because of the lack of light so there is no need for chloroplasts
Wiki User
∙ 12y agoOnion cells are plant cells, so they do have chloroplasts. However, it is too small to see through a microscope. If this question is for homework, do not rely on that specific answer.

Are chloroplasts visible in onion and cheek cells?
No chloroplasts in cheek and onion cells
What are 2 organelles not visible in onion cell?
Chloroplasts cannot be seen.Also centrioles are absent.
Why the chloroplasts is not present in the onion cell?
You can't see chloroplasts in an onion skin cell since the onion was underground. When the onion is underground, the sun can't reach the onion so the onion skin cells can't make glucose. The onion does have chloroplasts in its cells at the top of the onion. That's where he sunlight can reach the onion.
Where are the chloroplasts in the onion cells?
There are no chloroplasts in bulb.Thats because they do not get sunlight.
Do the cells of the onion bulb possess chloroplasts?
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.

Does a onion cell have a chloroplasts?
yes
Do onions have chloroplasts in their cells?
The bulb of the onion does not but the leaves of the onion plant do.
Why do onion cells do not have chloroplast?
Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.
Do the onion scale leaf cells contain chloroplast?
No. Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form.
Which structures can't be seen in an onion?
Chloroplasts
Does an onion have mitochondria?
Yes it has mitochondria.But it lacks chloroplasts.
Does the underground part of the onion have chloroplasts?
NO. It's a starch.
