What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
Where can you find onion epidermal cells?
Onion epidermal cells can be found on the outer layer of an onion bulb, specifically in the thin, transparent skin that covers the onion. This layer serves as a protective barrier for the bulb and is often used in biology labs for microscopic studies due to its easy accessibility and clear cell structure. To observe these cells, you can peel off a small section of the onion's skin and place it on a microscope slide.
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
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.
Why onion epidermal cell does not contain chloroplast?
chloroplasts contain chlorophyll which help to make the food for the plant (glucose). An onion is a bulb, it is food storage for the actual onion plant, it doesn't make its own food so doesn't need chloroplasts *Chloroplasts are used for photosynthesis (I) Hope it helps (Y)
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.
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 cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
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 cell of onion peel?
The cell of an onion peel is a plant cell. The cells of the onion peel do not have chloroplasts because the onion bulb (white part) grows under ground and its cells do not carry out photosynthesis.
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.
Where can you find onion epidermal cells?
Onion epidermal cells can be found on the outer layer of an onion bulb, specifically in the thin, transparent skin that covers the onion. This layer serves as a protective barrier for the bulb and is often used in biology labs for microscopic studies due to its easy accessibility and clear cell structure. To observe these cells, you can peel off a small section of the onion's skin and place it on a microscope slide.
Why are chloroplasts absent in onion epidermal cells and potato tubular cells?
Onion epidermal cells and potato tuber cells do not contain chloroplasts because they do not require photosynthesis for energy production. These cells mainly function in storage and support, so they do not need chloroplasts for the process of photosynthesis.
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
What are tube like pockets of epidermal cells that extend into the dermis?
Hair follicles are tube-like structures that extend from the epidermis into the dermis. They are comprised of epidermal cells and contain the hair shaft.
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.
Why are no chloroplasts fond in the onion cells?
Onions are underground structures. They do not get sunlight.
