- The cytoplasm is a jelly-like substance that fills the cell, serving as the environment where cellular components operate. It comprises the cytosol, organelles, and the cytoskeleton. The cytosol, a watery solution, facilitates biochemical reactions essential for life.

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.

Cytoplasm: A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen. Nucleus
The basic subcellular structures of an eukaryotic cell as seen by transmission electron microscopy (TEM). Try to identify the cell borders and nuclei. Switch between the grayscale and color images (see above) to help identify the following structures: Plasma Membranes.
- Cell surface membrane. The structure of the cell surface membrane – although the structure looks static the phospholipids and proteins forming the bilayer are constantly in motion.
- Cell wall. The cell wall is freely permeable to most substances (unlike the plasma membrane) Cell walls are formed outside of the cell membrane and offer structural support to cell.
- Nucleus. The nucleus of a cell contains chromatin (a complex of DNA and histone proteins) which is the genetic material of the cell. Present in all eukaryotic cells, the nucleus is relatively large and separated from the cytoplasm by a double membrane (the nuclear envelope) which has many pores.
- Mitochondria. A single mitochondrion is shown – the inner membrane has protein complexes vital for the later stages of aerobic respiration embedded within it.
