<h3><u>Answer;</u></h3>
<em>D. Have different structures and different functions</em>
A plasma membrane and a cell wall <em><u>have different structures and different functions</u></em>.
<h3><u>Explanation;</u></h3>
- <em><u>Plasma membrane</u></em> is a structure that is found in <u><em>both animal cell and plants cells</em></u>. It is made up of a <u><em>bi-layer consisting of lipid and proteins</em></u>. Plasma membrane are semi-permeable which means the<em><u> allow selective movement of materials in and out of the cell. </u></em>
- <em><u>Cell wall</u></em>, on the other hand is a structure that is found on plant cells and lacks in animal cell. It <em><u>contains cellulose in its structure </u></em>which enables it to be rigid and enhances it <em><u>protect the cell from mechanical damage</u></em> from harsh conditions such as pressure in the outside environment.
