Cell Modification

It is a tail-like projection that protrudes from the cell body of certain prokaryotic and eukaryotic cells, and functions in locomotion.

• Flagella

• Cilia

• Microvilli

• Extracellular Matrix

Act as barriers that regulate the movement

of water and solutes between epithelial layers

• Desmosomes

• Gap junctions

• Tight Junctions

• Cell Junctions

Are one form of communicating

junctions that allow small inorganic ions and

water-soluble molecules to pass directly from

the cytoplasm of one cell to another.

• Gap junctions

• Desmosomes

• Tight Junctions

• Cell Junctions

It is found in bladder intestines and kidney

• Gap Junctions

• Tight Junctions

• Cell Junctions

• Desmosomes

It is found skin and intestines

• Desmosomes

• Tight junctions

• Cell junction

• Gap junctions

It is a meshwork of proteins and

polysaccharide in close association with

the cell

• Extracellular Matrix

• Microvilli

• Cilia

• Flagella

are slender protuberances that project from the much larger cell body.

• Cilia

• Flagella

• Microvilli

• Extracellular Matrix

is a structural protein that helps to resist stretching.

• Fibronectin

• Integrin

• Collagen fibers

• cell wall

is an adhesive protein attached to the integrin.

• Collagen fibers

• Fibronectin

• Integrin

• Cell wall

are integral membrane protein

attached to the cytoskeleton which is

inside the cell.
