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 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 epithelial classification?
Epithelial tissue is a major category of tissue which lines all our body surfaces. It can be classified by a combination of shape (squamous, cuboidal, columnar) and layers (simple, stratified, pseudostratified).
What structure is present in eukaryotes but not in prokaryotes?
dna
What is the difference between the epidermis of human and invertebrates?
The epidermis of humans is typically multilayered, with specialized cells like keratinocytes that produce keratin to provide protection. In invertebrates, the epidermis is usually a single layer of cells responsible for secretion of cuticle or exoskeleton for support and protection. Additionally, human epidermis often contains melanocytes responsible for pigmentation, which is not typically present in invertebrate epidermis.
How does the structure of epithelial tissue help it to perform its function?
It is specialized to form the covering or lining of all internal and external surfaces.It is a made up of many cells that are closely packed with no intercellular spaces. It is separated from the underlying tissue by a basement membrane.This membrane provides structural support for the epithelial tissue.
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 are stratified epithelial present?
the lining of the esophogus
What is present of observe?
Observing.
Which method can typically observe tissue structure?
Histology is the method used to observe tissue structure by studying thin slices of tissues placed on slides and stained with dyes to highlight different structures. This technique allows for the visualization of cells, their organization, and any abnormalities present in the tissue.
What does it mean when you have epithelial cells present in a pap smear?
Epithelial cells are a normal part of the anatomy. They are the type of cell checked in a pap smear. If they are present, it's a sign that the pap smear got a decent sample.
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.
Is the inside of the gut covered by epithelial tissue?
Yes, the inside of the gut is lined with epithelial tissue. This epithelial layer helps with absorption of nutrients and acts as a barrier against harmful substances that may be present in the gut.
Is epithelium present only in the epidermis?
Epithelial tissue is present in many areas of the body, including the linings of body cavities and tubes.
What does osmosis require that this structure be present?
What does osmosis require that this structure be present?
How do you observe the present tense?
I am observing you from over here.
What tissue organ and system are epithelial cells in?
Epithelial cells are found in epithelial tissue, which is a type of tissue that lines the surfaces and cavities of the body. Epithelial tissue is present in various organs throughout the body, such as the skin, lungs, stomach, and intestines. Epithelial cells play a role in protecting underlying tissues, regulating the passage of molecules, and providing sensory functions.
Which type of epithelial tissue is present in the organs where exchange of substance take place?
Simple squamous epithelium is the type of epithelial tissue present in the organs where exchange of substances takes place, such as in the lungs for gas exchange or in the kidney for filtration. This type of tissue is thin and allows for efficient diffusion of substances.
