Membrane bound or not, Double Membrane.. Help Please...

[Persona]

I need to figure whether certain organelles are membrane bound or not and whether or not they have double membranes. I'm assuming that those with double membranes are membrane bound. So far this is what I've come up with, please help me fill in the rest and correct me if you see any mistakes. If I've left something blank, it just means that I'm stupid and have no idea what it is >.>Thank you in advance.

Nucleus - Double
Nucleolus
Chromatin
Nuclear Envelope - Double
Smooth/Rough Endoplasmic Reticulum - Membrane Bound
Golgi Body
Central Vacuole
Lysosomes - Membrane Bound
Peroxisomes
Chloroplasts - Double
Mitochondria - Double
Microfilaments
Ribosomes - Some membrane bound, some not
Plasma Membrane
Cell Wall
Centrioles
Microtubules
Cilia
Flagellum

Yeah... I know a lot of htem are blank... I guess I just fail at life -_- Once again thanks in advance.

Heres your updated version:

Nucleus - Double
Nucleolus- no
Chromatin- no
Nuclear Envelope - Double
Smooth/Rough Endoplasmic Reticulum - Membrane Bound
Golgi Body- Membrane Bound
Central Vacuole- Membrane Bound
Lysosomes - Membrane Bound
Chloroplasts - Double
Mitochondria - Double
Ribosomes - Some membrane bound, some not
Cilia-No, because it is incased in the cell’s plasma

Flagellum- No, because it is incased in the cell’s plasma
