The calvin cycle requires atp and nadph, products of the light reactions. if a classmate asserted that the light reactions don't depend on the calvin cycle and, with continual light, could just keep on producing atp and nadph, how would you respond?

The Calvin cycle can occur in the absence of light.

Explanation:

100% correct

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
