Biology- Cells & Organelles

Animal cell structure:

• Cell surafce membrane
• Rough endoplasmic reticulum (RER)
• Nucleolus
• Nucleus 
• Smooth endoplasmic reticulum (SER)
• Mitochondria 
• Cytoplasm 
• Gologi apparatus
• Nuclear envelope
• Ribosome
• Lysosome

Plant cell structure: (everything everything the same as an animal aprat from                                                                                                           lysosomes)

• chloroplasts 
• Plasmodesmata
• Vacuole

Function of organelles: 

Plasma membrane- Regulates movement of substances in and out of a cell. Also has receptor molecules which allow response to chemicals e.g. hormones.

Cell wall- Supports plant cells.

Nucleus- Contains DNA which are instructions to make protiens. The pores allow for substances to move in and out of the cytoplasm. Nucleolus maks ribosomes.

Lysosome- Contains digestive enzymes.

Rough endoplasmici reticulum (RER)- Folds and processes proteins that have been made at the ribosomes.

Smooth endoplasmic reticulum (SER)- Synthesises and processes lipids.

Vesicle- Transports substances…
