Question

1. what are the intercellular junctions between plant cells? plasmodesmata allow small molecules (like water, ions, and some small proteins, and rna). 34. animal cells do not have plasmodesmata. this figure shows the three types of intercellular junctions seen in animal cells. label each type and summarize its role. tight junctions: desmosomes: gap junctions:

Explanation:

Tight junctions form a seal between cells, preventing leakage of substances between them. Desmosomes are like "spot - welds" that provide strong adhesion between cells, giving tissues mechanical strength. Gap junctions are channels that allow for the direct passage of small molecules and ions between cells, enabling communication and coordination.

Answer:

Tight junctions: Form a seal to prevent substance leakage.
Desmosomes: Provide strong cell - to - cell adhesion for tissue strength.
Gap junctions: Allow direct passage of small molecules and ions for cell communication.
