Meaning and Definition
The clear, fluid portion of the cytoplasm within a cell, excluding organelles and other inclusions.
In cytology, the liquid, transparent ground substance of the cytoplasm in which organelles and particles are suspended; sometimes synonymous with cytosol, though hyaloplasm may also refer to the more homogeneous, non-granular part.

FAQ
Frequently Asked Questions
No. Cytoplasm refers to the entire contents of the cell inside the membrane but outside the nucleus (including organelles). Hyaloplasm refers specifically to the clear, fluid part of the cytoplasm excluding the organelles.
Almost exclusively in older or very specialised textbooks and academic papers on cell biology, cytology, or histology. It is rarely used in modern, general scientific communication.
It serves as the medium for suspending organelles, facilitates intracellular transport of molecules, and is the site for many metabolic reactions.
For modern usage, 'cytosol' is the preferred and more precise term. 'Hyaloplasm' can sound archaic or overly specific to a certain model of cell structure.
The clear, fluid portion of the cytoplasm within a cell, excluding organelles and other inclusions.

Memory Aids
Mnemonic
Think of HYALO like 'hyaline' (clear/transparent) and PLASM like 'cytoplasm.' It's the clear, fluid part of the cytoplasm.
Conceptual Metaphor
The clear soup (broth) of the cell in which the solid ingredients (organelles) float.
