Do epithelial tissues always exhibit polarity?
Yes, all epithelial exhibit what is called apical-basal polarity
What is the function of basal cell and terminal cell in plant embryo development?
terminal cell : provide polarity to the embryo and embryo develops here.. (apical cell) basal cell : develops suspensor which anchors embryo to the endosperm and serve as a nutrient producer.
What type of tissue has an apical and basal surface?
Epithelial tissue lines body surfaces and cavities as have apical and basement sides.
What are 6 special characteristics of epithelium?
1. Cellularity: composed entirely of cells 2. Polarity: Apical vs. Basal Surface 3. Specialized Contacts: special cell junctions (Tight, Gap and Desmosomes) 4. Avascular but Innervated: contains NO blood vessels but has nerve endings 5. Regeneration: high regenerative capacity 6. Deep in Epithelia, there's always Connective Tissue
What is an apical cell?
an apical cell is the top layer of the epidermis.

Does All epithelia have an apical surface and a basal surface?
YES
What type of tissue has an apical and basal surface?
Epithelial tissue lines body surfaces and cavities as have apical and basement sides.
How do avascular tissue receive nutreints?
By diffusion or absorption across the apical or basal surfaces of Epithelium.
An epithelial cell can be divided into two functional regions They are the surface and the surface?
An epithelial cell can be divided into basal and apical functional regions.
What are ten different cell parts in a human epithelial cell?
The cell parts of an epithelial cell include; apical and basal regions and a basement membrane (basal lamina). Epithelial cells are held together by desmosomes, adherens, tight junctions and gap junctions.
What multilayered epithelium with cuboidal basal cells and flat cells at its surface would be classified as?
Multiple cell layers whose apical cells are flattened are stratified squamous. These are epithelial cells arranged in layers upon a basal membrane.

Is the Sodium Potassium pump located on the apical membrane?
Sodium Potassium pumps are located on your body cells. This pump is used as a type of active transport to let these ions into and out of your cell.
What are the characteristics of epithelia tissue?
Epithelia tissues consists of closely-packed cells arranged in one or more flat sheets. Their apical surface is exposed to the external environmental while their basal surface is attached to the tissue beneath it. The connective tissues link the epithelial cells to other structures. Nutrients travel to the epithelia tissues via diffusion through the capillaries.
What is apical pulse?
apical pulse is actually the heartbeat
