Answer:
Cell membrane
Explanation:
Cell membrane is an important part in cell which performs various vital functions. It is not only a simple boundary that surrounds the protoplast rather it is a semi permeable membrane structurally made of proteins and lipid bilayer and regulates the transport of different materials across it.
It regulates the following transports -
- Disposal of wastes
- Export and import of nutrients
- Export and import of various ions
- Export and import of gases
Because all of the nutrients comes from the mother, and her umbilical cord. What ever mom put inside her body goes inside the baby’s body. It can also be in her breast milk. That’s why when your breast feeding you can’t drink.
