The plasma membrane is a selective barrier that controls the movement of molecules between the inside and the outside of the cell: cells can be classified as prokaryotes or eukaryotes, which differ in the degree of internal compartmentalization. The endomembrane system is an interconnected system of membranes that includes the nuclear envelope, endoplasmic reticulum, golgi apparatus, lysosomes, vesicles, and plasma membrane: mitochondria and chloroplasts are organelles involved in harnessing energy, and likely evolved from free-living prokaryotes. All organisms are made up of cells. The cell is the fundamental unit of life. Robert hooke used a simple microscope to observe small chambers in a sample of cork tissue that he des(cid:272)ri(cid:271)ed as (cid:862)(cid:272)ell(cid:863) Cell membrane are composed of two layers of lipids. The major type of lipid found in the cell membrane are phospholipids.
