Question

1. list the structure(s) that form the boundary between the inside and the outside of each cell in model 2.
2. what is different about the outermost boundary in a plant cell compared to an animal cell? plant has a cell wall animal does not

Explanation:

1. In animal cells, the cell - membrane forms the boundary. In plant cells, the cell - wall and cell - membrane together form the boundary.
2. The outermost boundary in a plant cell is the cell - wall which is rigid and provides structural support and protection. Animal cells lack a cell - wall and only have a cell - membrane as their outermost boundary.

Answer:

1. In animal cells: Cell membrane. In plant cells: Cell wall and cell membrane.
2. A plant cell has a cell - wall as its outermost boundary which an animal cell does not have.
