The parasite (sporozoite) enters the host's cells and grows while feeding on the cell contents.
During asexual reproduction the cell contents divide and form motile spores that arrange themselves into colonies before being liberated.
Proteins are synthesized by ribosomes that are either attached to the endoplasmic reticulum or suspended freely in the cell contents.
The cell contents, particularly its ions (electrically charged atoms) then leak through the hole and it dies.
The nematode pushes the stylet into plant cells and injects a liquid containing enzymes, which digest plant cell contents.
Unlike many other aschelminthes, nematodes have sperm cells that are amoeboid; i.e., their cell contents seem to flow.
Some unicellular organisms are capable of amoeboid movement, in which the cell contents flow into extensions, called pseudopodia, from the cell body.
Within a growth ring, those cells responsible for the conduction of water rapidly become devoid of cell contents because they must be empty and dead at functional maturity.
The magnifying powers of the microscope and the inadequacy of techniques for preparing cells for observation precluded a study of the intimate details of the cell contents.
A few insects (e.g., some caterpillars and aquatic midge larvae) tolerate ice formation in body fluids, although it is probable that the cell contents do not freeze.
The cell contents of the prey are transported up through the feeding tentacles into the suctorian, where digestive vacuoles are formed.
