2. Cell (Plasma) membrane
4. A cell membrane is made of phospholipids, is flexible, and is found in animal cells. A cell wall is made of cellulose, is rigid, and is found in plant cells.
Answer:
An invasive species thrives in its new ecosystem and out-competes native species. So, some factors are dominance, environment, predators, and resource availability.
New, more adaptable species flourish, replacing the extinct species.
The selection pressures before the extinction tend to favor a certain type of organism and the sudden shift in conditions help others move up the food chain.

Prokaryotic cells are the most primitive type of organism that do not possess a true nucleus in them. They do not even have true membrane-bound organelles.
The prokaryotes have a plasma membrane as their protective covering which helps them to survive in extreme conditions.
They also possess a rigid cell wall which also provides them protection and rigidity. Example: Archaea and bacteria.
