Cis and trans refers to the different faces of a Golgi complex. Vesicles come into the cis face from the ER and leave from the trans face to the plasma membrane or Lysosomes.

Which organelle is composed of a series of channels throughout the cytoplasm that functions in the transport of molecules?
Yes. It was exempliflied by endoplasmic reticulum (ER), Cis-trans Golgi network ( CGN and TGN), endosome(lysosome), Its involve a series of transportation channel.
What are the steps of the secretory pathway?
Protein SynthesisEndoplasmic Reticulum-->cis Golgi cisternae --> medial Golgi cisternae --> trans Golgi Cisternae --> Plasma membraneExtra Cellular SpaceAs they are being synthesized, secretory proteins enter the lumen of the endoplasmic reticulum. From the ER, vesicles transport these proteins to the Golgi, where they are sequentially modified and concentrated in a cis-to-trans direction. Secretory vesicles bud from the Golgi and move along cytoskeletal filaments to eventually fuse with the plasma membrane, secreting their protein cargo. Each of these transport steps requires specialized proteins to ensure that the cargo is sent to the proper location and is able to fuse with the target membrane.
What condition is cause by incubation of cells at 20 c blocks the releases of proteins from the trans Golgi?
a decrease in exocytosis
What is the narrow flat membranous structure ofa Golgi body is termed as?
The "stacks of pancakes" are vesicles with a trans and cis face.
What correctly describes an endomembrane function?
Products of the ER are usually modified during their transit from the cis to the trans region of the Golgi apparatus.
Why it is said Golgi complex has a polarity?
That's because Golgi complex is really spatially orientated (it does not have any random orientation) in the cell - the "cis" part of Golgi is close to endoplasmic reticulum and the "trans" part of Golgi is distant from endoplasmic reticulum. Proteins and lipids coming from endoplasmic reticulum enter Golgi at its "cis" part and across the Golgi network, they are transported towards the "trans" part, from where they are excreted either to other parts of the cell, or more usually, they are transported to plasmatic membrane.
Is Golgi complex present in both plant and animal cells?
Yes, it is present in both, it's used for packaging ribosomes, it has Cis and Trans sides.
What is the significance of the cis and trans sides of the Golgi apparatus?
hahaha....
If you were a protein destined to reach the plasma membrane and you were making your way through the Golgi when suddenly Golgi trafficking was blocked at the trans face what would happen to you?
If you were a protein destined to reach the plasma membrane and you were making your way through the Golgi when suddenly Golgi trafficking was blocked at the trans face, what would happen to you?
If you compared the proteins in a cis Golgi compartment with those in a trans Golgi compartment you would find?
contain fewer modifications
How do proteins and other substances get from Endoplasmic Reticculum to Golgi apparatus?
Transport vesicles. Perhaps by motor proteins and entering the trans side of the Golgi.
What organelles possesses a cis and trans side composed of cisternae?
Golgi apparatus

Do proteins from the RER have to cross the Cytosol to join the Cis Golgi?
Yes, in vesicles, though there may be confusion between cis and trans here. The confusion may be mine though.
What is the difference between cis- and trans-fatty acids?
Just the difference between cis and trans isomers. The arrangement of functional groups around double bonded carbons. Same groups lined up on the same side are cis fatties and alternate groups lined up on the different sides are trans fatty acids.
A cell organelle that helps make and package material to trans port out of the cell?
That's the Golgi apparatus.
