In plants,there is cellwall.In animals,there is a layer with phospholipids,proteins and collegen etc.
Nuclear Envelope or Membrane
Cell membrane
There are 2, surrounding a water layer.
cell membrane
the cell wall
The outer layer of a serous membrane is called the parietal layer and is always attached to the surrounding tissues. The inner layer is called the visceral layer and is firmly attached to the organ it covers
The membrane surrounding the nucleus is simply called the nuclear membrane. It is a phospholipid bilayer. The nuclear membrane merges with the endoplasmic reticulum, and you can learn more by using the link below.
The semipermeable outside layer surrounding the contents of a cell
The cell membrane. Also plants only have cell walls.
arachnoid membrane
The animals outer layer is called the cell membrane. The plants cell membrane still exists, but it has another layer surrounding the membrane called the cell wall.
