What is the best reason for an organelle to have folded membranes inside it?

Having folds increase surface area.So their functions can be done efficiently.Example-mitochondria.

Why mitochondria is organelle but not a cell?
Main reason is it is found inside a cell.But according to endosimbiotic theory mitochondra is a pre prokariyotic cell.
Why are membranes a advantage to a cell?
The membrane allows the cell to keep all its resources and materials together. Otherwise everything would drift away. The cell membrane is permeable to some materials, allowing them to pass through into the cell without energy expenditure. Similarly the membrane is impermeable to some materials. This allows the cell to do things like create a charge or concentration gradient by using active transport of the material. This is how cells maintain their Na and K concentrations which is very important to cell function.
How do organs in the ventral body benefit by being surrounded by double-layered membranes instead of single-layered membranes?
The main reason is for fluidity and ease of friction in the ventral cavity. double sacs provide protection and allow for the organs to move/slide easier with one another.
What is the main reason Na and K ions CANNOT easily diffuse through plasma membranes?
they are hydrophilic and can't cross the hydrophobic region of the plasma membrane
How does thyroxine pass through the plasma membranes?
diffusion. it is lipophilic and is able to pass through the PM. thyroxine is not water soluble and is the reason why it requires a carrier protein (albumin) for circulation.

Are phospholipids unicellular multicellular or both?
Phosholipids are molecules and therefore not cellular at all. However, phospholipids are the principle component of organelle and cell membranes in both unicellular and multicellular organisms, but they can't be called cellular for the same reason we don't call bricks buildings.
The number of membranes surrounding a mitochondria?
Two
What is diglycerol tetraether?
It is one of the molecules that build up the cellular membranes of archea. They span the whole membrane from inside out (in contrast to normal cell membranes where each phospholipid spans only "half" the membrane) which is probably one reason why archea are generally more tolerant against high temperatures.
If the company was closed what is your reason for leaving?
You left because you were made redundant when the company folded.
The reason only certain cells are affected is that the membranes of these cells have specific?
receptors

One reason the Precambrian rock record has been difficult to interpret is that it's rocks?
are severely bent and folded
Why are mantis legs folded and spiny?
A mantis' legs are folded for preparation to strike its prey. When the legs are folded they are always ready to extend them rapidly and catch its next meal off guard. That being said, the reason of the spiny "barbs" on the legs are to hook its catch and keep the insect close and not to escape.

Do you need to be in a warm environment to fight the common cold?
No. The reason colds are more common during the winter is because people spend more time indoors, living in recycled air. We are subjected to air in which sick people have been sneezing and coughing. During spring, summer and autumn outside air is circulated inside. Also, cold air is dryer, causing the membranes inside the sinuses to dry out. The dryer sinus membranes can more easily become infected. That's why humidifiers are so helpful when you have a cold.
What organelle is considered the energy central?
The Nucleus coordinates metabolic processes, reproduction and heritage, reason for why it is considered the cell's control center.
