Why do you see chloroplasts in the Elodea cell but not the onion cell?

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 needchloroplasts, so they dont have them.

∙ 11y agoAn onion is the root component of the onion plant and is essentially buried in the ground. Only the stem/leaves contain chloroplasts. Elodea is a green water plant and the leaves contain chloroplasts, the root system of Elodea doesn't contain chloroplasts.

∙ 7y agoThe onion is not a productive part of the plant: it is a storage root. The elodea leaves are engaged in photosynthesis (in sunlight) while the onion skin is around the onion, underground.
Wiki User
∙ 13y agocause onion cell grow underground, which means they dont need sunlight to live. Dont use photosynthesis.
Wiki User
∙ 11y agob'cos the onion is in the underground , only it's leaves can get chloroplasts from the sun.
gets mo?

Are there organelles in elodea?
Yes the organelles float inside the Cytoplasm inside the Elodea cells.
What is the microscopic structures make up organisms such as Elodea?
The 3 characteristics can be seen in elodea microscopically are cell wall, large central vacuole and chloroplasts. When looking under a microscope at elodea you can see the basic structure of plant cells.
What is the difference between an onion cell and a cheek cell?
Cheek cells are only found in animals, whereas onion cells are found in platns, particularly onion cells. Cheek cells, being animal cells, do not contain a cell wall as onion cells do becasue cell walls are found only in plant cells for structure and rigidness. Onion cells, unlike most plant cells, do not have chlorplasts becasue it does not need sunlight for photosynthesis as other plants do. Being grown underground, it receives nutrients directly from the soil, so chloraplasts are not evident. This is also why onions are never green, since chloroplasts contain chlorpohyll, a pigment which gives plants its green color. Basically, cheek cells are found in animals, and onion cells are found in plants.
Why is an onion cell a plant cell?
Onion cells have a cell wall made of cellulose, while animal cells don't have a cell wall. Also, onion cells would have chloroplasts and chlorophyll so they can do photosynthesis. And animal cells have organelles called either centrosomes or centrioles, and plants don't.
What plant organelle is missing from the onion cell?
Because, it is very small. You will need a electron microscope to see it.
Why do you need to stain the elodea cell?
to see the nucleus and watch the chloroplasts move to the center
What structure could you see in the Elodea cells?
The cell wall surrounding all plant cells
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.
Are there organelles in elodea?
Yes the organelles float inside the Cytoplasm inside the Elodea cells.
What is the microscopic structures make up organisms such as Elodea?
The 3 characteristics can be seen in elodea microscopically are cell wall, large central vacuole and chloroplasts. When looking under a microscope at elodea you can see the basic structure of plant cells.
Can you observe any chloroplast in the onion cell using microscope?
Yes, sometimes there will be green portions of the onion. If you look at those cells under the microscope, you will see chloroplasts.
What structures were you able to see in the onion cell?
The Human cell and Onion cell have Nucleus
Why would you not find a chloroplast in a onion root cell?
the reason you wouldn't see chloroplasts is because the onion root tip is underground where light can not reach and why would it need chloroplasts if it didn't need to produce energy form light?
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.
Why dont onion cell have chloroplasts and chlorophyll?
Chloroplasts contain chlorophyll which help to make the food for the plant (glucose). First, chloroplasts are essential for the process of photosynthesis. You need to know that the onion bulb we refer to in daily life grows underground, which is not exposed to the sunlight, it only stores food for the plant. And you also need to know, the process of photosynthesis, requires lights. Because onion bulbs are underground, what is the use of having chloroplasts? The onion plants have green shoots where there are chloroplasts. You can simply tell that there is no chloroplast in onion bulbs because they are not green. Onion bulbs just basically shares a similar environment with root cells.You can check the images in Google and you actually see that onion cell does not have any chloroplasts.
What is the difference between an onion cell and a cheek cell?
Cheek cells are only found in animals, whereas onion cells are found in platns, particularly onion cells.

Parts of an onion skin cell that you can not see?
the chloroplast
