In eukaryotic cells, cytoplasm refers to the contents of the cell with the exception of the 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.

Dec 5, 2023 · Structural support is provided by the polysaccharide cellulose in plants, and peptidoglycan in most bacterial cells. Narrow threads of cytoplasm (surrounded by a cell membrane) called plasmodesmata connect the cytoplasm of neighbouring plant cells.
Figure 01-08: TEM micrograph showing a 70,000× magnified portion of the cytoplasm of a plant cell. The ER, a Golgi stack, and some vesicles are visible. The structures are near the edge of the cell, as a cell wall is visible on the right-hand side of the image.
The cytoplasm refers to the entire region of a cell between the plasma membrane and the nuclear envelope. It is composed of organelles suspended in the gel-like cytosol , the cytoskeleton, and various chemicals (see figure below).
