Explain why cells have semi-permeable membranes. What are semi-permeable membranes, what do they help maintain, and what cell organelle helps regulate this?

Explanation:

I FEEEL UR PAIN I JUST TOOK THE TEST FOR THIS IN BIO... but anyways cells have semi-permeable membranes so they can let waste products out of the cell and other things in. A semi-permeable membrane is almost like a barrier with a gate around a cell, and they control what goes in and out of the cell I. Don't take my word for the maintaining part but I think homeostasis, and idk the last one.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
