Cytoplasm
In cell biology, the cytoplasm is all of the material within a 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. The main components of the cytoplasm are cytosol – a gel-like substance, the organelles – the cell's internal sub-structures, and various cytoplasmic inclusions. The cytoplasm is about 80% water and usually colorless.
Syllable
The "nucleus" is usually the vowel in the middle of a syllable. The "onset" is the sound or sounds occurring before the nucleus, and the "coda" (literally 'tail') is the sound or sounds that follow the nucleus. They are sometimes collectively known as the "shell". The term "rime" covers the nucleus plus coda. In the one-syllable English word "cat", the nucleus is "a" (the sound that can be shouted or sung on its own), the onset "c", the coda "t", and the rime "at". This syllable can be abstracted as a "consonant-vowel-consonant" syllable, abbreviated "CVC". Languages vary greatly in the restrictions on the sounds making up the onset, nucleus and coda of a syllable, according to what is termed a language's phonotactics.
