Plant cells complete cytokinesis differently from animal cells because they build a:

1. A rigid cell wall makes it impossible to constrict a plant cell from the outside. 2. The new boundary must therefore be built from the inside out. 3. In animal cells daughter cells are separated by an actin ring, whereas plant cells are separated by the cell plate. 4. That cell plate will grow into a new cell wall. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 10 'Cell Reproduction', sections 10.1-10.5_
