Dokumen tersebut memberikan informasi mengenai struktur dan fungsi sel secara umum. Sel dijelaskan sebagai unit terkecil yang hidup dan memiliki membran, inti, sitoplasma, serta organel-organel yang membantu fungsi sel seperti mitokondria dan retikulum endoplasma. Jenis-jenis sel dijelaskan antara lain sel prokaryotik dan eukaryotik beserta organisasi internalnya.

1. ORGANISASI SEL (The Organization of Cells) (BBC: K2-K4) Riyanto Sinaga, S.Si, M.Si

2. STRUKTUR DAN FUNGSI SEL: Suatu massa protoplasma yang dibatasi oleh cell membrane serta mempunyai nukleus A cell is the basic, living , structural and functional unit of the body.

7. Every Eukaryotic cell has three main parts: Plasma (cell) membrane - separates inside of cell from external environment. Nucleus – organelle that contains the cell’s DNA and is surrounded by a double membrane. Cytoplasm – everything from the nuclear membrane to the plasma membrane

8. Cytoplasm refers to cytosol plus organelles and inclusions. cytosol - contains proteins, enzymes, nutrients, ions, and other small molecules organelles - highly organized structures with characteristic shapes that are specialized for specific cellular activities. inclusions - are temporary structures in the cytoplasm that contain secretions and storage products of the cell.

9. Electron Micrograph

10. (Exists during cell division) (?)

14. Various cell types; shape, size, intracellular organizations, polarization – Functions These three cells all belong to “Intestinal Epithelial Cell” groups Small Intestine (Absorptions) Pancreatic Acinar cell (Digestive enzyme production) Liver Hepatocyte (Metabolism, protein production, Bile secretion etc)

31. Sistem Endomembran golgi apparatus - Receives proteins, lipids and other molecules from the ER via transport vesicles and chemically modifies them - Concentrates, packages and sorts proteins before being sent to their cellular or extra cellular destinations - Synthesizes some polysaccharides for plant cell walls Sorting, modifications and concentration in protein synthesis cis Golgi Network cis Golgi trans Golgi TGN (Trans-golgi Network) Each compartment is not continuous to the next one.
