What is between cells?

Answer 1

! If you mean animal cells, you are talking about the "extracellular matrix" (ECM), which is typically composed of proteins like collagen, of proteoglycans (e.g., chondroitin sulfate), and of pure glycosaminoglycans (usually pure hyaluronan). Some components of this ECM can be anchored to the animal cell plasma membrane, while others can be "free" in the matrix. Many solutes are present as well, including enzymes (proteins/glycoproteins). Connective tissues have an excess of ECM. "Chondrocytes", which the cells that make up the tissue "cartilage", have more ECM than cell proper by volume!

If you are talking about plant cells, you need to be specific. From one plant cell plasma membrane to the adjacent (second), you would find a cell wall (cellulose, other carbohydrates, and protein), then the middle lamella (mainly pectin), and then the second cell's wall, and finally the second cell's plasma membrane. The cell walls themselves may be primary and secondary, with the secondary wall being laid down later in development, and hence closer to the plasma membrane. Less specifically, you could say the middle lamella is found between plant cells, if you include the cell wall as part of the plant cell.

Answer 2

The extracellular matrix is a complex mixture of proteins and other molecules found between cells. It provides structural support, facilitates cell communication, and plays a role in cell adhesion and migration. The extracellular matrix is essential for maintaining tissue integrity and function.

Answer 3

plant cells have cell wall btw them and animals cell membranes

Answer 4

Intercellular fluid.
