Eukaryotic Organelles

Nucleus

• Surrounded by a double membrane, which contains many pores. These pores are in abundance, suggesting communcation between nucleus and cytoplasm is important. 
• Contains chromosomes- thread like structures appear dispered as a diffuse network, called chromatin.

Mitochondria

• Bounded by a double membrane. the outermembrane is smooth, whilst the inner has many folds called cristae. These folds enchance producivity of cellular respiration by increasing its high surface area.
• Is the site of celluar resperation, thus being the cells "power producers".
• Located in the cytoplasm.

Ribosomes

• Is the site of protein synthesis.
• Do not have membranes.
• Are contructed of protein and the nucleic acid RNA.

Endoplasmic reticulum (ER)

Consists of a network of folded single membranes forming interconnected sheets, tubes or sacs. The origin of the E.R. is the outer membrane of the nucleus, to which it may remain attached.

• Rough endoplasmic reticulum (RER)
  • Has ribosomes attached to the outer…
