Why do eukaryotic cells have organelles?

Definition

Compartmentalizing processes allows the cell the maintain different chemical conditions, concentrate certain enzymes and substrates. and prevents incompatible reactions from interfering with one another

Term

Cytosol

Definition

- Site of most metabolic functions and processes - Site of protein synthesis (translation in eukaryotes and prokaryotes) - Has a cytoskeleton (network of protein filaments) throughout that provide structural support, maintain cell shape, anchor organelles, facilitate intracellular transport, and enables cell movement.

Term

Nucleus

Definition

- Contains main genome (stores DNA) - Site of DNA replication - Site of transcription (DNA -> RNA) - Main site of ribosome synthesis - Has a double membrane - outer is continuous with the ER membrane - Has pores that facilitate the movement of proteins, RNA, etc in and out of the nucleus - Has heterochromatin (highly condensed chromatin consisting of DNA wrapped around histones)
