A class is creating a model of a plant cell that shows some of the structures that are likely to be observed in a typical plant cell. Students in the class have proposed revisions to make it a more accurate model of a plant cell. Which TWO of the following proposed changes will make the model more accurate? A B C Adding ribosomes because plant cells perform protein synthesis D Adding cilia or a flagellum because plant cells need a structure to help them move E F Adding Golgi apparatus because plant cells package and export proteins from the cell Removing the large vacuole because plant cells do not need to store water Removing the mitochondria because plant cells use chloroplasts for ATP production Removing the cell membrane because plant cells have only a cell wall 11 Q 8 ? € Submit

Structure and Composition of Cell Membrane

Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.

Cell Membrane

The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment. 

Prokaryotes vs Eukaryotes

The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
