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.
Unlike the plant cell, this matrix is not a cell wall which is quite strong and thick in plants. This is one of the primary differences in the two types of cells. Plant cells have a cell wall and animal cells do not have cell walls. Animal cells have an extracellular matrix or ECM (Raven, 82). The other method you can use to learn the differences in the two types of cells is to sketch each cell and label all structures, interior and exterior.
