Structures in plant leaves that open and close to maintain homeostasis are called stomata. This is where gases would diffuse in and out of the leaf.
Red is dominant in comparison to white. Hence there will be more red flowers than white as white it the reccessive genotype.
Since mitosis is the division of cells, in this case, skin cells, it allows the dead skin cells to fall off. Also, mitosis can fix any injuries. Without mitosis, these things would not happen.
Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!
Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.
But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!
