Search the entire root tip for cells in interphase, prophase, metaphase, anaphase and telophase as well as cells that appear to be undergoing cytokinesis. You do not need to differentiate between early and late stages, but be consistent in how you differentiate between the five stages and cytokinesis. Draw cells from the onion root tip that are "classic" examples of each of the five stages and cytokinesis. Include in each formal drawing, the boundaries of the surrounding cells.

A drawing of the cells will reveal the stages of the plant division

Explanation:

A drawing of the plant cell will reveal the different stages of cell division. This results in the division stages in the chromosomal splitting. In the drawings, its noteworthy to note that plant cell division undergoes through a process of meiosis, unlike the animal cell that undergoes the process of mitosis. The plant cell is different as the organelles in the cytoplasm are different from the cells in a mammalian cell. In addition, the animal cell does not have the cytokineses stage.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

i am going to guess that it is co2.
