- In cell biology, the cytoplasm is a highly viscous (gel-like) substance enclosed within the cell membrane. It's composed of water (about 85 percent), proteins (10 to 15%), lipids (2 to 4%), nucleic acids, inorganic salts and polysaccharides in smaller amounts.

Apr 27, 2017 · Cytoplasm refers to the fluid that fills the cell, which includes the cytosol along with filaments, proteins, ions and macromolecular structures as well as the organelles suspended in the cytosol. In eukaryotic cells, cytoplasm refers to the contents of the cell with the exception of the nucleus.
Jul 19, 2024 · Cytoplasm, the semifluid substance of a cell that is external to the nuclear membrane and internal to the cellular membrane, sometimes described as the nonnuclear content of protoplasm. In eukaryotes (i.e., cells having a nucleus), the cytoplasm contains all of the organelles.

Apr 12, 2019 · The cytoplasm is the gel-like material that constitutes most of the interior of biological cells. In prokaryotes, it is essentially everything inside the cell membrane; in eukaryotes, it holds everything inside the cell membrane, in particular the organelles.
2 years ago. A plasma membrane is a layer around a cell that prevents the cytoplasm from getting all mixed up with the outside environment. Plasma membrane (cell membrane) is made of two phospholipid layers, or a type of lipid with hydrophilic heads on the outside and hydrophobic tails inside.
- Nice question! A membrane is not a rigid structure. It is fluid and is able to move which actually gives it more stability. As an analogy, think of...

In cell biology, the cytoplasm describes all material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm.
Aug 2, 2024 · The cytoplasm functions to support and suspend organelles and cellular molecules. Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis ), mitosis, and meiosis.
