SAS 2- Tissues

Which of these is NOT one of the four basic tissue types?

A. Glandular

Which of the following statements is true? (Select all that apply)

A. Transitional epithelium has cells that change shape when the tissue is stretched. B. Transitional epithelium is found in the lining of the urinary bladder, the ureters and the superior urethra. C. Transitional epithelium is pseudostratified. D. As transitional epithelium is stretched, the number of cell layers increases. E. Transitional epithelium is found in cavities that can expand greatly in volume.

Movement of substances from a lower to a higher concentration and requires ATP.

Active Transport

Known as the programmed cell death

Apoptosis

All are true statement about epithelial tissue: (Select all that apply)

B. Epithelial tissue provides physical protection for organs. C. Epithelial tissue functions in absorption & secretion. D. Epithelial tissue controls the permeability into and out of an area/organ.

Which of the following characteristics of tissues and cells would aid in diffusion or the movement of materials into and out of the body through the epithelium?

B. a single layer of relatively flat, thin cells

Epithelium that consists of a single layer of cells, in which some cells are tall and thin and reach the free surface and others do not, is classified as:

B. pseudostratified columnar epithelium

The most correct classification of an epithelial tissue consisting of many layers of cells, in which the outer layers are flat and thin, and the basal layers are cuboidal or columnar is:

C. stratified squamous epithelium.

The cell's framework

Cytoskeleton

Basement membranes:

D. function as a filter and barrier to cell or pathogen movement, attach epithelial cells to the underlying tissue and are secreted partially by epithelial cells and partially by the cells of the underlying tissue are true of basement membranes.

Epithelial cells that appear cube like when an organ is relaxed and flattened when the organ is distended by fluid are classified as:

D. transitional epithelium.

Movement of a solute from an area of higher concentration to an area of lower concentration within a solvent.

Diffusion

Understanding tissue structure and function is important because:

E. All of these are correct

Epithelial cells:

E. have all of these properties

A process in which the information in DNA directs protein synthesis

Gene Expression

Type of solution in which the water moves by osmosis out of the cell and into the solution, resulting in shrinkage

Hypertonic

Major site of ATP synthesis.

Mitochondrion

Process of cell division

Mitosis

Enumerate the four stages of mitosis (in order).

Prophase, Metaphase, Anaphase, Telophase

Site of CHON synthesis.

Smooth Endoplasmic Reticulum
