What cell parts appeared common to all the specimens observed under HPO paramecium squamous cell onion root cell?
Under high power objective (HPO) microscopy, both Paramecium and onion root cells exhibit common cellular structures such as the cell membrane, cytoplasm, and nucleus. The cell membrane serves as a protective barrier, while the cytoplasm contains various organelles essential for cellular processes. In both specimens, the nucleus acts as the control center, housing genetic material. Although Paramecium is a single-celled organism and onion root cells are part of a multicellular plant, these fundamental components remain consistent across both types of cells.
What is length of an onion epidermis cell?
The length of an onion epidermal cell is typically around 0.2 to 0.5 millimeters.
What cell parts if any were seen exclusively in each specimen under hpo paramecium squamous and onion root cell?
Under high-power objective (HPO) microscopy, Paramecium cells exhibit unique structures like cilia, which are used for locomotion and feeding, and contractile vacuoles for osmoregulation, not found in the other specimens. Squamous epithelial cells, typically seen in animal tissues, contain tight junctions and desmosomes, which are specialized for cell-to-cell adhesion. In contrast, onion root cells display characteristic features such as large central vacuoles and cell walls, which are absent in the other specimens. Each specimen reveals distinct cellular adaptations suited to their specific functions and environments.
What is the average length of an onion epidermis cell?
The average length of an onion epidermis cell typically ranges from about 30 to 100 micrometers. These cells are elongated and can vary in size depending on the specific part of the onion and environmental conditions. Generally, they are used in educational settings to study plant cell structure due to their accessibility and distinct characteristics.
What is onion epidermal cell?
an onion cell stores foodThe epidermis is the outermost layer of the skin, it acts as the body's major barrier against the environment. It is the thinnest on the eyelids at and the thickest on the palms.
How many layer thick is the epidermis?
Answer: the epidermis of a leaf includes: upper epidermis and lower epidermis but if you are referring to the epidermis of an onion: it is only one layer
How are paramecium and amoeba similar to onion?
A paramecium and an amoeba are eukaryotes, as are onions.
What cell parts were seen exclusively in paramecium squamous cell and onion root cell?
In paramecium, the presence of cilia is a distinctive feature, as these hair-like structures aid in movement and feeding. In contrast, onion root cells exhibit a prominent cell wall and large central vacuoles, which are not found in paramecium. While both cell types have organelles like nuclei and mitochondria, the specific structures highlight their differing functions and adaptations to their environments.
Is onion epidermis a tissue?
no
What is outer epidermis of an allium?
the skin of an onion
How do you pick up onion epidermis?
To pick up onion epidermis, you use forceps to pick it up, and afterwards, to see the cells, you would use a clean slide, iodine and a cover slid. Hope that helped!
What is the shape of the cells of the onion epidermis?
these plastids contain chlorophyl.what kind of plastids are they?
What is length of an onion epidermis cell?
The length of an onion epidermal cell is typically around 0.2 to 0.5 millimeters.
What is the function of these epidermis onion cells?
The root cell's job is to gather minerals and and take it up the roots to the onion.

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.
Why obtain a thin layer of the onion epidermis?
Obtaining a thin layer of the onion epidermis is a common practice in biological studies, particularly for observing cell structure under a microscope. This transparent layer allows for easier viewing of individual plant cells, their arrangement, and organelles, facilitating the study of plant tissue characteristics. Additionally, it serves as a simple and effective way to demonstrate concepts such as cell walls, membranes, and the effects of staining techniques in educational settings.
