Answer:
cell membrane
Step-by-step explanation:
- The cell membrane plays the same role in the cell as the skin plays in our body
- It shields our internal organs as the cell membrane does the same for protecting the other organelles [there is also a cell well in plants]
- Similarly, as our skin allows water and sunlight to enter our cells, the cell membrane also constricts entry of foreign particles, and allows for the required transport of sugars, proteins, water, etc.
