Eastern Red Cedar ----juniperus virginiana. It normally grows 30 or more ft tall with some specimens reaching over 80 ft and 30 ft wide. It can live a very long life with some specimens in Iowa are over 500 years old on rocky high spots.
Phragmoplast and cell plate formation in a plant cell during cytokinesis. Left side: Phragmoplast forms and cell plate starts to assemble in the center of the cell. Towards the right: Phragmoplast enlarges in a donut-shape towards the outside of the cell, leaving behind mature cell plate in the center. The cell plate will transform into the new cell wall once cytokinesis is complete.
In animal cells (have no cell walls), the cell is pinched in half by a belt of protein threads but in plant cells (have rigid cell walls), the cytoplasm is divided in a different way. Vesicles holding cell wall line up across the middle of the cell. These vesicles fuse to form a large membrane-bound cell wall called cell plate.
