- Organelles
- The Nucleus
- The largest organelle, when stained it shows darkened patches known as chromatin
- Surrounded by a nuclear envelope, it is made up of two fluid filled membranes
- Houses most of genetic material. Nucleolus makes RNA and ribosomes.
- Endoplasmic Reticulum
- Consists of flattened membrane filled sacs.
- RER transports proteins made in the ribosomes attached.
- SER is involved in making the lipids cells need
- Golgi Apparatus
- Membrane bound, flattened sacs
- Recieves proteins from ER and modifies them.
- Mitochondria
- Spherical shaped with two membranes. Inner membrane form cristae, central part forms matrix
- Site where ATP is produced.
- Spherical shaped with two membranes. Inner membrane form cristae, central part forms matrix
- Chloroplasts
- Found in plant cells. Have two membranes. Inner membrane is continuous network of flattened sacs called thylakoids
- Site of photosynthesis.
- Found in plant cells. Have two membranes. Inner membrane is continuous network of flattened sacs called thylakoids
- Lysosomes
- Spherical sacs surrounded by single membrane
- Powerful digestive enzymes that brake down materials
- Spherical sacs surrounded by single membrane
- The Nucleus
