State the unique characteristics of epithelial tissue.​

Biology
1 answer:
erica [24]3 years ago
7 0

Answer:  

Characteristics of epithelium tissue

1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)

2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.

3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.

4.Avascular– Epithelium typically lacks its own blood supply.

5.Regeneration– Epithelium cells can regenerate if proper nourished.

6.Absence of nerves (except for a few axons in the deeper layers)

Classification scheme of epithelial tissue:

Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.

Why are xylem vessels more efficient in the transport of water than tracheids​
Paha777 [63]

Explanation:

  • The vessels of the xylem are more efficient than the tracheids in water conduction due to the presence of perforations in them. These perforations allow for the continuous flow of water into the xylem vessels.The xylem tracheids are long, narrow, tubelike cells. The walls of tracheids are thick and hard.

What is osmosis? ???​
lisov135 [29]

Answer:

In biology, osmosis is defined as the net movement of water molecules through a semipermeable membrane (e.g. cell membrane) from an area of higher to an area of lower water potential. Other definitions of osmosis are as follows:

The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration

The tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances) across a semipermeable membrane

In chemistry, osmosis is defined similarly. It is the passage of a pure solvent from a solution of lesser to one of greater concentration of solutes when the two solutions are separated by a membrane that selectively prevents the passage of solute molecules while allows the solvent molecules to pass through.

How is diversity in a population created?​
Lemur [1.5K]

Answer:

I don't know what type of diversity, but I know genetic diversity

Explanation:

genetic diversity is controlled by 4 processes. mutation, drift, migration and selection. each of them have a analogue at the level of species. speciation creates new species much as mutation creates new alleles
