How do ribosomes fuse with the rough ER.

# data[].attributes.body
The two subunits of a ribosome snap together over the starting end of the messenger RNA. Then, if the protein (polypeptide) to be made is for export out of the cell, the ribosome docks with the ER and makes the polypeptide directly into the lumen of the RER.

You have to have lots of different kinds of specialized (confusing) parts to make something as specialized and confusing as us.

Why does it always seem like the names for cells always come from Greek roots?

# data[].attributes.body
Most things in science were named in the 18th and 19th centuries when educated people all studied latin and greek as schoolchildren. It was a second language to them and was very natural to use when they discovered things.

What is the purpose of a nuclear pore inside the Endoplasmic Reticulum, if the Endoplasmic Reticulum is sealed off from the cytoplasm, and is already connected to the nucleus?(As shown below)

What is the purpose of a nuclear pore inside the Endoplasmic Reticulum, if the Endoplasmic Reticulum is sealed off from the cytoplasm, and is already connected to the nucleus?(As shown below)

# data[].attributes.body
Some of pores lead into the ER, but some pores communicate directly with the cytoplasm (everything leaving the nucleus doesn't have to pass through the ER).
The pores leading to the ER helps transfer certain things in and out of the nucleus efficiently.

Does the smooth endoplasmic reticulum not being continuous with the nuclear envelope affect its function?

Does the smooth endoplasmic reticulum not being continuous with the nuclear envelope affect its function?

# data[].attributes.body
I don't think so -- since it's not receiving messenger RNA from the nucleus like the rough ER is (to make proteins), it doesn't need to be as close or in as intimate contact.

An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells. You can think of organelles as smaller rooms within the factory, with specialized conditions to help these rooms carry out their specific task (like a break room stocked with goodies or a research room with cool gadgets and a special air filter).[from Khan academy]

Why do we have to find the volume/surface area of cells? 

# data[].attributes.body
There are certain surface area to volume ratios that "work" but when the ratio gets too low the cell can't survive.

No. Prokaryotes divide into two more prokaryotes while eukaryotic cells divide into more eukaryotic cells.

Why do we use surface area and volume to find the size of the cell?

# data[].attributes.body
Usually cells are described by their length or diameter (depending on their shape).
SA and volume are important in determining "what sizes they can be" and still survive. As cells get bigger, they have less surface area compared to their volume.

Since it is an entire single-celled organism, it has to perform all the functions of life - energy acquiring, movement, reproduction, homeostasis. Prokaryotes are very simple but very efficient.

what does membrane bound mean? i don't get it
I means it is made (or wrapped) by a membrane. Most of the stuff in the cell is similar to the cell membrane.

# data[].attributes.body
There definitely are smaller things than cells, but cells are the smallest thing that has all the char. of life. Interestingly, there are about the same number of atoms in a cell as there are cells in a human body (via thoughtco.com).

Then why do we call them the building blocks of the universe. that Just seems confusing..

Yes, unless they are collected and put into a growing environment.
