Pseudopods are temporary, regular lobes formed by amoebas and some other eukaryotic cells.
TRUE
FALSE
The tight junction has groups that are arranged into strands that form a branching network, with larger numbers of strands making for a tighter (a) .

Cadherins
Integrins
Claudins
Connexins
In apical modification, pseudopods bulge _______ to move the cell or engulf prey.
inward
outward
This type of junctions fastens cells to one another.
Tight junction
Gap junction
Adhering junction
Extracellular matrix has (a) secreted by the cell on its apical surface.
Pseudopods came from the Greek words pseudes and podos and are under what type of modification?
Apical Modification

The specialized or modification re-acquired by the cell after cell division that helps the cell in different beneficial ways is called ____ ____________.
(a)
These connect two cells together and these are even stronger connections that join the intermediate filaments of neighboring cells.
Hemidesmosomes
Claudins
Desmosomes
Connexins
This cell modification is found on the surface of the cell.
Lateral Modification
Basal Modification
Apical Modification
In vertebrates, gap junctions develop when a set of (a) membrane proteins called connexins form an elongated, donut-like structure called a connexon.
