When the surface area of the membrane is enlarged, then the rate of diffusion (think of it as the rate of which materials move in and out of the organelle) also increases, making the transfer of nutrients and waste quicker. However, as the surface area increases, so must the volume increase. The ratio, then, between surface area and volume decreases.
Sound weird? Take this for an example: a 1cm cube has a surface area of 6cm^2, and a volume of 1cm^3, for a surface area to volume ratio (SA:V) of 6:1, or 6. A 2cm cube, however, would have a surface area of 24cm^2 and a volume of 8cm^3, for a SA:V of 24:8, or simplified to lowest terms and converted into a whole number, 3. As you can see, the SA:V is constantly decreasing as volume and surface area increase.
This poses a problem to the organelle, because if it was simply going to grow bigger, then its SA:V would decrease, and there would eventually be so much volume that the rate of diffusion cannot keep up with the amount of stuff it has to go through.
A work-around for the cell would then be to increase its surface area as much as possible while increasing its volume as little as possible.
Thus, the need for a folded membrane!

What is the difference between double membrane cell organelles and single membrane cell organelles?
The plasma membrane is the phospholipid bilayer that is defines the outer border of the cell. All of the organelles (which are also membrane bounds) are contained within the boundaries of the plasma membrane.
Does a Peroxisome have a double membrane?
No, peroxisomes do not have a double membrane. They are single-membraned organelles that contain enzymes involved in various metabolic reactions, such as detoxification of harmful substances and fatty acid metabolism.
Do all organelles have a membrane?
None of the organelles have membrane.young chek
Which of the three microbes has many organelles?
EukaryotesEukaryotes have specialized and membrane-bound structures which are the "organelles". Examples of organelles are: Mitochondria, Chloroplasts, and Gogi bodies.
Do plant cells have membrane bound organelle?
Yes, plant cells do have membrane-bound organelles. Some examples include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vacuoles, and chloroplasts. These organelles have specialized functions that contribute to the overall functioning of the plant cell.

What is the purpose or usefulness of organelles that have a double membrane?
Mitochondria (producing cell energy), and chloroplast (photosyntesis) are the organelles with double membrane. Endosymbiotic theory - during evolution smaller prokaryots were consumed by bigger cells, and developed protective coat, hence the double membrane
Surrounded by double layer of memberane with pore?
The mitochondria and the chloroplast are organelles that have a double membrane.
What are the two organelles that are double membraneous?
The two organelles that are double membranous are the mitochondria and the chloroplasts. They both have an outer membrane and an inner membrane, which helps compartmentalize their functions within the cell.
Does a Peroxisome have a double membrane?
No, peroxisomes do not have a double membrane. They are single-membraned organelles that contain enzymes involved in various metabolic reactions, such as detoxification of harmful substances and fatty acid metabolism.
Is it true that Mitochondria are double membrane organelles.?
No,it is not the only organelle. Many other organelles have double membranes. Ex: Chloroplast,lysosoem,vacuole etc

What do organelle do not have?
There are so many different types of organelles. This therefore means that the organelles do not have various things depending on the particular type. Most organelles do not have a double membrane.
Which organelles developed nuclear membrane?
The nuclear membrane, as the name suggests, is the membrane around the nucleus. If you meant to ask which other organelles are membrane bound, then there are a few. Some examples are mitochondria and chloroplasts.
What three orgenelles have a double membrane?
The three cell organelles that have double membranes are: 1. Nucleus 2. Mitochondria 3. Chloroplast
