Question

Animal cells are connected by _______

• A. Desmosome
• B. Cell wall
• C. Cell Membrane
• D. Plasmodesmata

Answer 1

Answer:

D. Plasmodesmata

• Plasmodesmata are thin strands of cytoplasm that connect the cytoplasm of adjacent cells, allowing for the exchange of materials such as proteins and ions.

• Animal cells are connected by plasmodesmata, while plant cells are connected by desmosomes and a cell wall surrounding them.

• Function of Desmosomes:

  Desmosomes are crucial in maintaining tissue structure and integrity, especially in high-stress environments such as:

  Skin: Desmosomes prevent cells from separating in the epidermis, enabling the skin to resist tearing and stretching.

  Cardiac Muscle: In the heart, desmosomes hold muscle cells together during contraction, preventing them from pulling apart due to the stress of continuous beating.

  Epithelial Tissues: They provide stability and protection to epithelial layers lining organs and cavities.
