WebApr 1, 2024 · What is the Structure of Cells? All eukaryotic cells consist of three basic parts. These are the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the outside of the cell, the nucleus is found in the middle of the cell, and the cytoplasm fills the gap between the two. WebAug 13, 2024 · The plasma (cell) membrane separates the inner environment of a cell from the extracellular fluid. It is composed of a fluid phospholipid bilayer (two layers of phospholipids) as shown in figure 4.1. 2 below, and other molecules. Not many substances can cross the phospholipid bilayer, so it serves to separate the inside of the cell from the ...

WebAll cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts. Cells contain parts called organelles.
