CELL JUNCTIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Platelets are small cellular fragments that have no nucleus. Their job is to clot together at tears and cuts in the skin to prevent bleeding out of the organism. Which type of junction would you expect to form between platelets?
A
Gap
B
Tight
C
Adhering/Desmosomes
D
Plasmodesmata
Explanation: 

Detailed explanation-1: -In Summary: Cell Junctions Plasmodesmata are channels between adjacent plant cells, while gap junctions are channels between adjacent animal cells. However, their structures are quite different. A tight junction is a watertight seal between two adjacent cells, while a desmosome acts like a spot weld.

Detailed explanation-2: -The correct answer is option (c) tight junctions.

Detailed explanation-3: -Answer and Explanation: The difference between desmosomes and gap junctions is that desmosomes anchor cells together and do not allow for the transfer of materials whereas gap junctions do. Desmosomes are like spot welds between two cells and anchor them together only in one place.
