answers: cytosol
context: molecules responsible for most cell contractions and movements. Groundplasm Groundplasm is the submicroscopic ground cell substance or cytoplasmatic matrix which remains after exclusion of the cell organelles and other particles. It is the "hyaloplasm" of light microscopy, and the high-complex, polyphasic system in which all of the resolvable cytoplasmic elements are suspended, including the larger organelles such the ribosomes, mitochondria, the plant plastids, lipid droplets, and vacuoles. Groundplasm contains most of the intermediate enzymes of cell metabolism, including those involved in preliminary or alternative pathways of ATP synthesis. It holds the metabolic cell reserves and the main cellular pool of </s> as well as soluble proteins and small structures such as ribosomes, proteasomes, and the mysterious vault complexes. The inner, granular and more fluid portion of the cytoplasm is referred to as endoplasm. Due to this network of fibres and high concentrations of dissolved macromolecules, such as proteins, an effect called macromolecular crowding occurs and the cytosol does not act as an ideal solution. This crowding effect alters how the components of the cytosol interact with each other. Organelles (literally "little organs"), are usually membrane-bound structures inside the cell that have specific functions. Some major organelles that are suspended in the </s> Nucleoplasm Similar to the cytoplasm of a cell, the nucleus contains nucleoplasm, karyoplasm, or nucleus sap. The nucleoplasm is one of the types of protoplasm, and it is enveloped by the nuclear membrane (also known as the nuclear envelope). The nucleoplasm includes the chromosomes and nucleolus. Many substances such as nucleotides (necessary for purposes such as the replication of DNA) and enzymes (which direct activities that take place in the nucleus) are dissolved in the nucleoplasm. The soluble, liquid portion of the nucleoplasm is called the nucleosol or nuclear hyaloplasm. The term "nucleoplasm" was coined by van Beneden (1875), while
