Xylem and Phloem. They are both part of the vascular tissue. Xylem is responsible for the movement of water and minerals from the roots to the leaves for photosynthesis. Phloem transports the sugar made during photosynthesis from the leaves to different parts of the plant. I'm pretty sure that water is included when the sugar is transported (in phloem) but you should just check if water is transported after photosynthesis just to make sure
Griffith concluded that the R-strain bacteria must have taken up what he called a "transforming principle" from the heat-killed S bacteria, which allowed them to "transform" into smooth-coated bacteria and become virulent.
Binary fission is simple ad rapid compared to mitosis that involves complexities like breaking down the nuclear membrane – which prokaryotes do not have – and replicating the many chromosomes – when prokaryotes have only one.
Replication of the circular DNA in prokaryotes happens as the process of division of the cell happens. In mitosis, the replication of all the genetic material must finish before the process of cytokinesis begins.
Spindle fibers are not formed in binary fission while they are significant in mitosis in drawing different chromosomes to different poles of the cell before cytokinesis.
