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 the final step, telophase, spindle fibers start to disappear, the chromosomes start to. uncoil, and two new nuclei form. Cell Division For most cells, after the nucleus divides, the. cytoplasm separates and two new cells form. In animal cells, the. cell membrane pinches in the middle, like a balloon with a. string tightened around it, and the cytoplasm divides. In plant cells, the appearance of a cell plate, as shown in Figure 4, tells you that the cytoplasm is being divided. New cell membranes form from the cell plate, and new cell walls develop from mole-cules released by the cell membranes. Following division of the cytoplasm, most new cells begin the period of growth, or inter-phase. Review cell division for an animal cell using the illustra-
