What are plant cells and animal cells?
This process allows the cell to maintain balance by controlling what enters and leaves.
What is homeostasis?
Damage to this organelle allows toxins in and causes important molecules to leak out.
What is plasma membrane failure leading to cell death?
These embedded structures act as channels, pumps, and receptors.
What are membrane proteins?
Even these simple cells must have a plasma membrane to survive.
What are prokaryotic cells (bacteria)?
This membrane function allows cells to respond to hormones and signals.
What is cell communication using receptor proteins?
This genetic disease is caused by a faulty plasma membrane protein affecting ion transport.
