One of the many good things about spring is that without it, and without the absence imposed by fall and winter, we flawed mortals might fail to appreciate the beauties around us. So much of the wonder of spring is found in the return of what was absent.
The second main difference is in the structure of the cell itself. Animal cells are smaller than plant cells and have a membrane around them that is flexible and allows molecules, gases and nutrients to pass into the cell. Plant cells are larger and in addition to a membrane they have a rigid cell wall.
Plant cells differ in structure from animal cells in that they have a cellulose wall that braces their plasma membranes. Animal cells lack this wall and therefore move with less difficulty than typical plant cells. Plant cells are eukaryotic, just as animal cells are, so both have a discrete nucleus.
