What else can I help you with?
Are chloroplasts visible in onion and cheek cells?
No chloroplasts in cheek and onion cells
What cells are in an onion tip but not the onion?
The cells in an onion tip but not the onion itself are usually actively dividing cells located at the growing tip of the onion root, known as the root cap cells. These cells help protect the delicate meristematic cells responsible for root growth and can often be found in the root zone of plants.
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.
What is the hypothesis of onion cell?
The hypothesis of observing onion cells under a microscope could be that the onion cells will have a distinct rectangular shape and contain a visible nucleus.
How do potato cells differ from onion cells?
Potato cells have larger, more angular shape and contain starch granules, while onion cells are smaller and have a more rectangular shape with a distinct cell wall. Additionally, potato cells lack the characteristic onion cell layers seen in onion cells.
When the onion and cheek epithelial cells was placed in the distilled water?
eat cholate
What would happen to red onion cell if sucrose solution added?
When a red onion cell is placed in a sucrose solution, water from inside the cell will move out due to osmosis. This will cause the cell to shrink and lose its turgidity as water moves from an area of higher concentration to lower concentration (from inside the cell to the solution outside).
What details can be observed when an onion slide is placed under a microscope?
When an onion slide is placed under a microscope, you can observe the cell structure, cell walls, cell membranes, and possibly the nucleus of the onion cells. The cells will appear as small, rectangular shapes with distinct boundaries. Additionally, you may see any organelles present within the cells.
Where are onion cells found?
All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
Are chloroplasts visible in onion and cheek cells?
No chloroplasts in cheek and onion cells
What cells are in an onion tip but not the onion?
The cells in an onion tip but not the onion itself are usually actively dividing cells located at the growing tip of the onion root, known as the root cap cells. These cells help protect the delicate meristematic cells responsible for root growth and can often be found in the root zone of plants.
Which of the 2 cells cheek or onion cells have a regular arrangement and structure?
Between the 2 cells that are cheek and onion cells, the one that has a regular arrangement and structure are onion cells. Cheek cells have an irregular shape.
What would happen if an onion is placed in water?
Nothing. The onion will get wet.
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.
What happens to an onion cell when placed in baking soda solution?
When an onion cell is placed in a baking soda solution, which is basic, it can undergo changes in its osmotic balance. The high concentration of sodium bicarbonate may cause water to move out of the onion cells, leading to plasmolysis, where the cell membrane pulls away from the cell wall. As a result, the onion cells may appear shriveled and less turgid. The basic environment can also affect the cell's internal pH and potentially impact cellular processes.
When the onion cell is placed in the pure water the size of the cell would be bigger after one hour but when you placed the cheek cell into the pure water it will burst why is that so?
An Onion cell as a contractile vacuole. This allows the cells to remover more water especially when placed into a hypotonic solution. An epithelial skin cell of the cheek does not have a contractile vacuole. The acess water cannot be stored, therefore the cell bursts.
What is the hypothesis of onion cell?
The hypothesis of observing onion cells under a microscope could be that the onion cells will have a distinct rectangular shape and contain a visible nucleus.
