To protect itself from harmful chemicals, such as Cornpops.
Lysogenic viruses destroy their host cell immediately.
Platelets are the cell pieces that form clots and seal up cuts.
of course animal cell as it cannot produce by itself
The queen lays an egg in a cell within the hive or in the nest in the wild. After three days the egg will develop into a larva and the worker bees will then seal (cap) the cell with wax. After 21 days, 24 if a drone, the young bee will eat the wax capping of the cell and release itself from the cell.
The cell has a lipid bilayer with embedded proteins that gives it shape. The cell membrane is rather fluid but also slightly rigid. This allows the cell to change shape but it cannot change shape very much. The membrane can seal itself if pierced by something very thin like a pin.The cell membrane holds it together as it's made of phospholipids.
Zygote is immediately produced when an animal's egg cell is fertilized by the sperm.
It depends on the way the puncture occurs.If to big of a rupture is created in a cell wall, the contents of the cell will leak out and the cell will die.However, a cell wall can reseal itself after certain insults. Neuropsychologists can insert a pipet into a single living neuron. The cell will seal itself around the pipet and the neuropsychologist can record the actual electrical impulses from within the cell.It is also possible to use a pipet to insert genetic material into an egg cell. The cell will not only recover, but it can divide and reproduce using the new genetic material.
host cell
A stem cell
Why ask? Don't you know? In the first place, look at the name itself. It said "Envelope Seal" therefore it is invented by a seal(sea lion).
Inside the cell itself.
A virus the immediately takes over a cell's functions is an active virus. An active virus causes the host cell to make new viruses, destroying the host cell.
