The greatest volume in an onion epidermal cell is occupied by the central vacuole. This large, fluid-filled organelle stores various substances, including water, nutrients, and waste products, and helps maintain turgor pressure, which is essential for the structural integrity of the cell. The vacuole also plays a role in regulating cell growth and maintaining the overall health of the plant tissue.
What else can I help you with?
Where are the epidermal cells of an onion located?
The epidermal cells of an onion are located on the outermost layer of the onion bulb, forming a protective barrier.
Does an onion epidermal cell have depth?
yes
What is a epidermal cell?
it is a thin layer that can be peeled out from an onion.
What structure observe in onion epidermal cells are not present in human epithelial cells?
The structure of onion epidermal cells refers to the arrangement of tissues in this cells. You can find the structure of onion epidermal cells online athttp://biology.touchspin.com/onion_epidermis.php. The structures observed in an onion epidermal cell, which are not present in the human epithelial cells are cell wall, central vacuole and vacuolar membrane.
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 structure can be seen in Elodea leaf but not present in epidermal cells of onion cells?
Chloroplasts can be seen in Elodea leaf cells but not in the epidermal cells of onion cells. Chloroplasts are responsible for photosynthesis in plant cells, containing chlorophyll that captures sunlight for energy production. Onion epidermal cells do not contain chloroplasts as they do not perform photosynthesis.
What is length of an onion epidermis cell?
The length of an onion epidermal cell is typically around 0.2 to 0.5 millimeters.
Why half of the onion epidermal cell is in darkness under the microscope?
becuse of the lodine solution
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.
Where can you find onion epidermal cells and what is their significance in plant biology?
Onion epidermal cells can be found in the thin, transparent layer on the surface of an onion bulb. These cells are significant in plant biology because they are commonly used in science experiments to study cell structure, division, and function. They are also used to observe processes such as osmosis and plasmolysis.
What is the size of an epidermal onion cell?
The average epithelial Onion Cell is 30.2 to 35.4 micrometers in diameter. I just did this exercise in cell bio lab.
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
