Within a plant cell, starch is basically stored energy. Starch is composed to cross sugar molecules that are cross linked to form larger chains of sugar molecules that are better for storage. When the need arises, these larger chains are broken down to sugar molecules and are utilized by plant cells to carry out various biological processes.
Starch is a large polymeric structure and does not typically pass through cell membranes.

∙ 13y agoYes. The membrane has little holes on it, and starch can pass through. The conditions on either side of the membrane are the ones that determine it.
Yesterday in my Biology class we did an experiment with corn starch, iodine, water, a beaker and a plastic baggie. You pour about 1 tbsp of corn starch into the baggie and pour clean water (tap water) into it so it looks like milky water. Make it go to one corner of the bag. Next, pour more tap water into a beaker, or a clear glass cup. Add iodine into it so that it looks like apple juice. Set the corner of the baggie into the glass or beaker (the corner with the starch & water.) let sit over night, and the result is...
The iodine an water mixture seaped

∙ 9y agoStarch cannot pass through a living cell membrane. This is mainly because the starch molecules are usually to large to pass through the cell membrane.

∙ 15y agono it can't. it has to be broken down into glucose.

What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
What is the name of the process of diffusion through a cell membrane?
Osmosis
Osmosis is the diffusion of what subtance through a cell membrane?
Water.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
Can phenolphthalein pass through a cell membrane?
Yes but not through simple diffusion
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
What is faciillitated diffusion?
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
How does sodium ion molecule move into the cell through cell membrane?
Through diffusion.
What is the diffusion of water through a cell membrane known as?
it is called Diffusion o Osmosis?
What is the diffusion of water through the cell membrane is called?
Facilitated Diffusion
Function of the cell membrane of a cell?
The transport of molecules into and out of the cell through osmosis and diffusion
What is the thin cell covering through which diffusion takes place?
cell membrane
Osmosis is the diffusion of what substance through a cell membrane?
Water
What is the name of the process of diffusion through a cell membrane?
Osmosis
Osmosis is the diffusion of what subtance through a cell membrane?
Water.
Where does diffusion takes place?
In a cell in the human body diffusion takes place in the cell membrane. The cell membrane allows smaller sized molecules to pass through.
