The endoplasm is necessary for most metabolic activities, including cell division. [1] The endoplasm, like the cytoplasm, is far from static. It is in a constant state of flux through intracellular transport, as vesicles are shuttled between organelles and to/from the plasma membrane. Materials are regularly both degraded and synthesized within ...
Ectoplasm (also exoplasm) is the non-granulated outer part of a cell's cytoplasm, while endoplasm is its often granulated inner layer. It is clear, and protects as well as transports things within the cell. [1] Moreover, large numbers of actin filaments frequently occur in the ectoplasm, which form an elastic support for the cell membrane. [2]
The concentrated inner area is called the endoplasm and the outer layer is called the cell cortex, or ectoplasm. Movement of calcium ions in and out of the cytoplasm is a signaling activity for metabolic processes. [3] In plants, movement of the cytoplasm around vacuoles is known as cytoplasmic streaming.
The ectoplasm consists of a gelatinous semisolid called plasma gel whereas the endoplasm is made up of a less viscous fluid called plasma sol. The ectoplasm owes its highly viscous state, in part, to the cross-linking actomyosin complex.

It's flu season right now, and the U.S. is in the midst of a wave that's straining hospitals. But not all influenza is the same. There are some notable differences between flu A and flu B strains ...
This problem can be scary—here's what to do about it. You probably don’t think too much about eating. You pop something in your mouth, chew it up and swallow it.
Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm. During locomotion, the endoplasm flows forwards and the ectoplasm runs backwards along the outside of the cell.
