- Eukaryotic Cells
- Nucleus
- Surrounded by a nuclear envelope, which contains pores. Containschromatin and often a structure called the nucleolus. The nucleolus makes ribosomestitled
- Mitochondria
- Has double membrane- inner is folded to form structures calledcristae. Inside is the matrix, which contains enzymes involved in respiration. Site ofaerobic respiration, where ATP is produced.
- Ribosomes
- A small organelle that floats free in the cytoplasm or is attached to rER. The site where proteins are made.
- Endoplasmic Reticulum
- A smooth ER is a system of membranes enclosing a fluid-filled space. Rough ER is similar, but covered in ribosomes. sER synthesizesand processes lipids, rER folds and processes proteins that have been made at the ribosomes.
- Lysosomes
- A round organelle surrounded by a membrane, with no clear internal structure. Contains digestive enzymes, they are kept separate from the cytoplasm by the surrounding membrane and can be used to digest invading cells or break downworn out components of the cell
- Golgi body
- A group of fluid-filled flattened sacs. Vesicles often seen at edges.Processes and packages new lipids and proteins, also makes lysosomes.
- Vacuole and Tonoplast
- A fluid-filled space in the cytoplasm surrounded by a membrane called the tonoplast. It contains a solution of sugars and salts called the cell sap.
- Nucleus
