The difference between protoplasm and cytoplasm is that the former encompasses the cytoplasm and nucleus of a cell, whereas cytoplasm is the semifluid substance found below the membrane of the cell. This means that the difference is minor, as both terms can refer to roughly the same components of a cell with different levels of precision.Know More
Protoplasm is a word that has been phased out of use in modern biology due to its largely inaccurate origin. Nowadays, it refers only to the cytoplasm and the nucleus instead of implying that cells were only containers of protoplasm. Modern science has since discovered that cells are much more complex.
Cytoplasm is the substance that contains the organelles of cells that have a nucleus, surrounding the organelles like the mitochondria, the Golgi apparatus and the cytoskeleton. These components are all a part of a cell in the same way as large organisms have organs, performing vital functions for the cell's survival. For instance, the mitochondria produce energy in the form of adenosine triphosphate for the cell to use, the cytoskeleton maintains the cell's shape and structure, and the Golgi apparatus modifies, packages and sorts proteins for transporting to their cellular destinations later on.Learn more about Cells
The four main functions of the plasma membrane include identification, communication, regulation of solute exchange through the membrane, and isolation of the cytoplasm from the external environment. The plasma membrane is a semi-permeable phospholipid bilayer that contains a hydrophilic head and a non-polar hydrophobic tail. It contains hydrogen bonds between the phospholipids that help hold the plasma membrane together; cholesterol molecules are also embedded into the membrane for fluidity.Full Answer >
The fluid inside a cell is the cytoplasm. It can also be referred to as the protoplasm or the cytosol. The cytoplasm of the cell suspends all of the important organelles of the cell, including the mitochondria, the endoplasmic reticulum, the Golgi apparatus and the nucleus.Full Answer >
The cell membrane is a flexible membrane that surrounds all eukaryotic cells. The membrane holds all of the organelles inside of the cell and keeps certain solutes from coming into or leaving the cell.Full Answer >
A cell membrane is a thin layer that acts as a barrier that separates an individual cell or a cellular compartment from other surrounding structures. This dynamic layer plays an essential part in the transport of ions and nutrients.Full Answer >
