|
Lysosome (function) |
Digestive enzymes > break down nutrients, invading cells (e.g. bacteria) & dead cell parts |
|
|
Ribosome (function) |
Where proteins are made |
|
|
Rough Endoplasmic Reticulum (RER) (function) |
Folds (changes proteins shape) & processes (adds carbohydrate chains) proteins made at the ribosome |
|
|
Smooth endoplasmic reticulum (function) |
Synthesises (makes them) & processes (adds carbohydrate chains) lipids |
|
|
Golgi apparatus (function) |
- Processes (adds/removes carbohydrate chains) & packages proteins & lipids - makes lysosomes |
|
|
Mitochondria (function) |
aerobic respiration > produces ATP |
|
|
Cytoplasm (define) |
- contains enzymes & solutes - dissolved mineral ions, nutrients & waste |
|
|
Centrioles (function) |
Form spindle fibres which are used to separate chromosomes during mitosis |
|
|
Cell membrane (function) |
Controls what goes... into cell, nutrients e.g. glucose & our of cell, waste e.g. carbon dioxide |
|
|
Nucleus (function) |
- controls cell activity - DNA > instructions for making proteins - nucleolus makes ribosomes |
|
|
Lysosomes (define) |
- round organelle - membrane bound |
|
|
Ribosome (define) |
- very small organelle - made up of proteins & RNA - NOT membrane bound - 80S |
|
|
RER (define) |
- covered with ribosomes - system of membranes enclosing a fluid filled space (Membrane bound fluid filled sacs) |
|
|
SER (define) |
- NOT covered in ribosomes - system if membranes enclosing a fluid filled space (Membrane bound fluid filled sacs) |
|
|
Golgi apparatus (define) |
- grp of fluid filled membrane bound flattened sacs - vesicles at edges (Membrane bound fluid filled flattened sacs) |
|
|
Mitochondria (define) |
- oval (round) shaped - double membrane bound (has inner & outer membrane) - inside the inner membrane is the matrix - inner membrane folded to form cristae structures |
|
|
Centriole (define) |
- small, hollow, microtubules (tiny protein cylinders) |
|
|
Nucleus (define) |
- nuclear envelope (double membrane) which contains many pores - nucleus containing chromatin (made from DNA & proteins) - nucleolus |
|
|
Cytoplasm (function) |
Involved in metabolic reactions |
|
|
What is the difference between the nucleus & nucleolus (bonus Qu) |
1. Nucleus is a membrane bound organelle whilst the nucleolus is not 2. Nucleus is an organelle whilst the nucleolus is a sub-organelle 3. Nucleus contains lots of DNA whilst the nucleolus contains lots of RNA |
|
|
Nucleolus (structure) |
Made of RNA & proteins |
|
|
Nucleolus (function) |
Making rRNA from RNA |
