One of the main reasons plants do not usually
move from place to place is because they are
rooted into the ground by their roots; roots also
provide support so the plants don't fall over. The
roots are able to provide plants with water and
nutrients from the soil. Some roots are very
thick, like in trees, or can be thinner. Their
distribution and how far into the ground they grow
depends on the availability of water in the area
which they grow and the properties of the soil
they grow in (the longest roots would be in a
desert, and the shortest in a tundra).
Plants themselves usually do not move once they
begin to grow, however plants are constantly
moving. How? Because their seeds and pollen can be
transported from place to place by the wind or
insects. So one plant growing in one area could be
transported and grow in another area if pollen or
seeds disperse to that area. Individual plants
cannot move, but populations can if they are not
already rooted in the ground.
