Which structure in an onion epidermal cell is semipermeable?
The cell membrane is the semipermeable structure in an onion epidermal cell. It regulates the passage of molecules in and out of the cell, allowing only certain substances to pass through while restricting others.
What cell structures can be seen in a stain onion cell?
The structure that is seen is the cell wall. This keeps the shape of the cell and is only found in plant cells. The organelles that can be see in a stained onion cells all depends on your microscope. Under a x400 light microscope we could see the cell wall, cell membrane, nucleus and cytoplasm,
Do onion cell have a cell membrane?
Yes, onion cells have a cell membrane. The cell membrane is a semi-permeable barrier that surrounds the cell and controls the movement of substances in and out of the cell. It is an essential structure for maintaining cell integrity and function.
Is onion cell a eukaryote or prokaryote?
An onion cell is a plant cell, thereby it is eukaryotic. Prokaryotic cells are only found by bacterias.
Why can one nucleus be visible and the other is not in an onion cell that came right off of the onion?
There is only one nucleus per cell.
What cell structure gave the onion skin cells a more rigid shape than your cheek cells?
The cell wall in the onion skin cells gives them a more rigid shape compared to cheek cells, which lack a cell wall and instead have a flexible cell membrane. The cell wall provides structural support and protection for the cell, helping maintain its shape.
Is there more than one nucleus in an onion cell?
Yes, an onion cell typically contains one nucleus. The nucleus is an essential organelle that contains genetic material and controls the cell's activities. Onion cells are eukaryotic, meaning they have a defined nucleus.
Does an onion cell have more than one nucleus?
more than one cell cause of the many layers.
What is the structure of to celia?
Celia does not have a structure. It is the only cell part that does not have a structure.
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.
Can a cell have multiple nuclei within its structure?
No, a typical cell can only have one nucleus within its structure.
Do onion cells have a cell wall x cell membrane nucleus x nuclear envelope x cytoplasm x vacuoles and plastids?
Yes, onion cells have a cell wall, cell membrane, nucleus, nuclear envelope, cytoplasm, vacuoles, and plastids. The cell wall provides structure and support, the cell membrane regulates what enters and exits the cell, the nucleus houses genetic material, the nuclear envelope surrounds the nucleus, cytoplasm contains organelles, vacuoles store materials, and plastids are involved in photosynthesis and storage of pigments.
