Question

Differences between plant cells and animal cells in terms of cell-cell interactions?

Answer 1

Answer: Differences between the plant cell and animal cell in terms of cell-cell interactions are as follows:

Plant cells	Animal cells
Plant cells never move, as they are forever attached to their parent cells. They prefer Lineage-based development.	Animal cells tend to move as occurs during gastrulation in animal embryo development,
In both plants and animals, the extracellular matrix is found to be structurally complex. The plant cell walls have an analogous structure. In their cell wall, the major components are mainly polysaccharides with a highly charged pectic polymers	Animal tissues commonly vary in the amount of ECM ( extracellular matrix) they contain. In animals, the extracellular matrix is generally composed of glycosaminoglycans, such as hyaluronan and some fibrous proteins, such as collagen.
The cell-cell signaling molecules are likely to differ somewhat in both the plant and animal cell, as the cells in plants are extensively connected by the cell-cell cytoplasmic channel or the plasmodesmata.	Plasmodesmata and cell-cell cytoplasmic channels are totally absent in animal cells and no such structures are found in animal cells but cell-cell connections do exist in between the animal cells.
The plants lack in some kind of true classical adhesion proteins such as filamin, tensin, integrin, talin, and alpha-actinin, etc	Animal cells contain some classical adhesion proteins such as integrin, filamin, talin, vinculin, alpha-actinin, and tensin.
