Brainlies ! describe the structure of the cell membrane/plasma membrane. label and describe the functions of the proteins, carbohydrates and cholesterol.

The plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates, which decorate both the proteins and lipids and help cells recognize each other. Hope this helps :)

hope to be marked brainliest

not only is it colder, it also becomes darker, less salty, and more dense.
