2 subunits: large and small 2 types: free and unbound |
|
Endoplasmic Reticulum |
Smooth: NO ribosomes, involved in ion movement Rough: associated with nucleus, covered in ribosomes, site of translation |

|
Vacuoles |
Functions: 1) provide turgor 2) storage 3) accumulation 4) admits/prevents passage |

Cell wall |
• forms exoskeleton • functions: 1) structural support 2) maintains cell shape 3) protects protoblast • Composition: - pectins - Hemicellulose - Cellulose - Lignin ---> responsible for strength, waterproofs and formed by dimerisation and dehydration |
|
Water |
POLAR!! • O is more electronegative than H • e- in O-H aren't shared, so pulled towards O • O has negative charge • H has positive charge |
