Why are the numerous organelles not visible in the stained slide of the onion epidermis?
The numerous organelles in the onion epidermis are not visible in stained slides primarily due to the thickness of the tissue and the limitations of light microscopy. Additionally, the staining process may not selectively highlight all organelles, making them less distinguishable. The onion epidermis cells are also packed tightly, which can obscure individual organelles. Consequently, only the cell wall and larger structures may be visible under a standard microscope.
What else can I help you with?
What parts of the skin cell is visible?
The parts of a skin cell that are typically visible include the cell membrane, nucleus, cytoplasm, and sometimes organelles like mitochondria or endoplasmic reticulum. These structures can be seen using a light microscope.
What organelles become more visible after being stained with iodine?
Iodine stains starch blue. You will be able to see the plastids where the starch is stored in the cytoplasm.
What are two organelles that shoukd be visible in a cheek cell leb but arent due to the lighting?
They only thing you can see in a cheek cell would be the nucleus and the cellular membrane. These cells must be stained because they won't be visible under a light microscope all by themselves.
Name organelles that are visible in the cell?
Some organelles that are visible in the cell include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and vacuoles. These organelles can be observed under a light microscope due to their size and distinct structures.
What cell organelles are not visible in bacterium even with an electron microscope?
Bacteria have no organelles.
Whats organelles are visible when methylene blue stains a tomato cell?
When a tomato cell is stained with methylene blue, organelles such as the nucleus, vacuoles, and possibly some smaller structures like mitochondria or chloroplasts may become visible under the microscope. Methylene blue tends to bind to nucleic acids and can highlight these structures within the cell.
What organelle in a cheek cell are not visible under a light microscope?
The organelles in a cheek cell that are not visible under a light microscope are the ribosomes. These organelles are responsible for protein synthesis.
What are the five layers of the epidermis from deep to superficial?
Mammalian skin is composed of two primary layers:the epidermis, which provides waterproofing and serves as a barrier to infection; andthe dermis, which serves as a location for the appendages of skin;
What would you expect to see inside the stained cells nucleus?
It would be the color you stained.
What is the layer of the skin that we can see?
It is stratum corneum layer of epidermis on outer side of skin which is visible .
When are Chromosomes not visible?
Chromosomes are not visible during the interphase stage of the cell cycle when they are in their less condensed form. Additionally, chromosomes may not be visible if the cell is not actively dividing or if they are not stained for observation under a microscope.
What are differences in appearances of cytoplasm in stained cell and cytoplasm in unstained cell?
In stained cells, cytoplasm appears colored due to the binding of the dye to various cellular components, making structures like organelles and the cytoskeleton more visible under the microscope. In unstained cells, cytoplasm appears transparent or slightly opaque, making it difficult to observe specific cellular structures without staining. Staining enhances the contrast and visibility of cellular components, aiding in their identification and study.
