Because plant cells have a rigid cell wall
No chloroplasts in cheek and onion cells
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.
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.
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.
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.
eat cholate
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).
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.
All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
No chloroplasts in cheek and onion cells
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.
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.
Nothing. The onion will get wet.
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.
A onion cell is : 0.2 mm
All cells have cytoplasm, so yes, onion cells have cytoplasm.
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.
