GENERAL HISTOLOGY

Detailed explanation-1: -The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.

Detailed explanation-2: -The endoplasmic reticulum (ER) is the transport network for molecules targeted for certain modifications and specific destinations, as compared to molecules that will float freely in the cytoplasm.

Detailed explanation-3: -In general, the role of the cytoplasmic intracellular transport is to help move materials around the cell. This movement is accomplished by cytoplasmic streaming, also called protoplasmic streaming, see Figure 5.4.

Detailed explanation-4: -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.

Detailed explanation-5: -In plant cells, the liquid inside the central vacuole provides turgor pressure, which is the outward pressure caused by the fluid inside the cell.
