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.
Nucleus (video game)
The basic game consists of shooting bacteria or progressively larger and larger viruses, which break down into smaller viruses when shot, or if left alone combine themselves into ever larger viruses. Each level also has a number of cells which clump together and interact in a physical manner, the players can move them around and manipulate them with a traction beam to construct barriers to hide behind or to block of parts of the dynamically changing levels.
