Waterweed grows near the surface of the water in lakes and ponds. it often grows in dense clumps. it has been observed that the chloroplasts in this plant mkve around inside the cell. how might this be an advantage and disadvantage to the plant?

An advantage of moving chloroplasts is that they are able to orient themselves optimally to take advantage of sunlight for photosynthesis, however the direction of sunlight. A disadvantage is that more energy is used to reorient the chloroplast hence its benefits can be counter-intuitive.

Cell division is important to single celled organisms because it allows the cells to reproduce. through cell division, cells make exact copies of themselves. when single celled organisms go through cell division, they make exact copies of themselves which is how they reproduce.
