- Cells
- The Nucleus
- nuclear pores
- nucleoplasm
- surrounded by an nuclear envelope
- chromatim is the DNA found in the nucleoplasm
- nucleolus assembles the ribosomes
- Endoplasmic Reticulum
- Smooth ER lacks ribosomes
- synthesise, store and transport lipids and carbohydrates
- Rough ER has ribosomes on the outside of the membrane
- provides a large surface area and a pathway for transportation
- Smooth ER lacks ribosomes
- Epithelial Cell
- EUKARYOTIC
- distinct nucleus and membrane bound organelles
- EUKARYOTIC
- Golgi Apparatus
- lipids and proteins from ER pass through the golgi
- carbohydrates are added to make glycoproteins
- stacks of membranes containing vesicles
- transported in vesicles which move to the cell surface and release their contents
- labels the proteins so they are sent to the right place
- lipids and proteins from ER pass through the golgi
- Mitochondria
- matrix is the material containing the proteins and lipids
- cristae form on the inner membrane
- provide a larger surface area
- produce ATP
- double membrane
- Lysosomes
- breaks down material in phagocytic cells
- rekaese enzymes to the outside of the cell
- formed when the vesicle contains enzymes
- isolate the harmful enzymes from the rest of the cell
- Microvilli
- finger like projections that increase surface area
- Ribosomes
- 70S - prokaryotic cells
- 80S - eukaryotic cells
- The Nucleus
