The calcium concentration must be greater OUTSIDE
the cell than INSIDE the cell.
Explanation:
Calcium has a vital role in the body, it is necessary for:
- exocytosis
- muscle contraction
- normal excitability of neurons
- blood coagulation
- building and maintaining bones and teeth
- enzymatic activity
Of course not! There's lots of ways materials can enter. It also depends on the cell; whether it has cell wall and cell membrane or only cell membrane.
Besides diffusion, there's also osmosis and active transport.
If the cell has only cell membrane, it means it's partially permeable, which means osmosis can happen.
