Size of image/ Real size of the object 6 of 17 A micrometer is ...? μm 1mm/1000 7 of 17 Ultrastructure is...? Structure we can see under an electron microscope 8 of 17 What is the nucleolus? Dense spherical structure insid ethe nucleus, makes ribosomes and RNA that pass into the cytoplasm and that synthesis protein 9 of 17 What is the nuclear envelope? Surround the nucleus and is a double membrane with pores 10 of 17 What is RER? Transports proteins made by attached ribosomes 11 of 17 What is SER? Makes lipids and hormones 12 of 17 What is the Golgi Apparatus ? Stack of membrane bound flattened sacs, modifies protiens from ER and packages them into vesicles for transport 13 of 17 What are ribosomes?
