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.
Can you clearly see as a structure the cell membrane in check cells and the cell wall inthe onion skin clls?
Yes. If viewed under even a simple light microscope, the cell structure of a cheek cell and the cell walls of an onion cell can clearly be seen.
How is an onion cell specialised?
An onion cell is specialized for storage of nutrients. It has a large central vacuole that stores water and other molecules, while the cell wall provides structure and support. The outermost layer of the onion cell is specialized for protection against pathogens and physical damage.
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,
Why do we use NaCl in a plasmolysis of onion?
NaCl is used in plasmolysis of onion cells to create a hypertonic solution, causing water to move out of the cell and shrink the cell contents away from the cell wall. This helps in studying the structure of the cell membrane and cell wall under different conditions.
What is the structure and function of an onion epidermal cell?
The structure of an onion epidermal cell consists of a cell wall, cell membrane, cytoplasm, and a large central vacuole. The function of an onion epidermal cell is to provide protection for the plant, regulate water and nutrient uptake, and help with gas exchange through stomata.
What is the structure and function of an onion cell?
The structure of an onion cell includes a cell wall, cell membrane, cytoplasm, nucleus, and vacuole. The function of an onion cell is to store nutrients, provide support, and regulate the movement of substances in and out of the cell.
What is the structure and function of onion cells in plant biology?
The structure of onion cells consists of a cell wall, cell membrane, cytoplasm, and a large central vacuole. The function of onion cells is to store nutrients, provide structural support, and regulate water balance within the plant.
What is the structure and function of an onion cell labeled under a microscope?
The structure of an onion cell labeled under a microscope consists of a cell wall, cell membrane, cytoplasm, nucleus, and vacuole. The function of an onion cell is to store nutrients, provide structure and support, and facilitate cellular processes such as growth and reproduction.
How does the structure of an onion cell wall contribute to the overall function of the onion plant?
The structure of an onion cell wall provides support and protection to the cell, helping the onion plant maintain its shape and resist external stress. This allows the plant to grow and thrive in various environments.
What is the structure and function of onion cells labeled in a microscopic image?
The structure of onion cells consists of a cell wall, cell membrane, cytoplasm, and a large central vacuole. The function of these cells is to provide support and protection to the plant, store nutrients, and regulate water balance.
What structure did you only find in the onion cell?
Im guessing it can be similar cell as the cheek cell
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.
How would you describe the cytoplasm of an onion cell and a cheek cell?
The cytoplasm of both an onion cell and a cheek cell contains various organelles like mitochondria, endoplasmic reticulum, and ribosomes. In an onion cell, the cytoplasm is dense and filled with starch grains, while in a cheek cell, the cytoplasm is more watery and may contain enzymes for digestion. Both cytoplasms play a role in supporting the cell's functions and maintaining its structure.
Can you clearly see as a structure the cell membrane in check cells and the cell wall inthe onion skin clls?
Yes. If viewed under even a simple light microscope, the cell structure of a cheek cell and the cell walls of an onion cell can clearly be seen.
What structure did you see in both onion cell and cork cell?
Both onion cells and cork cells exhibit a distinct cell wall structure that provides rigidity and support. In onion cells, the walls are composed of cellulose and are more flexible, allowing for turgor pressure, while cork cells have a thicker, protective cell wall made of suberin, which gives them a more rigid and impermeable characteristic. Additionally, both cell types contain a central vacuole, which plays a role in maintaining cell turgor and storage. However, cork cells lack chloroplasts, unlike onion cells, which can have these organelles for photosynthesis.
How is an onion cell specialised?
An onion cell is specialized for storage of nutrients. It has a large central vacuole that stores water and other molecules, while the cell wall provides structure and support. The outermost layer of the onion cell is specialized for protection against pathogens and physical damage.
