Answer 1

the walls of ventricle are thicker than the walls of auricel because the Have to exert pressure to transport blood in all the parts of the body.

the water and minerals are transported in the plant by the suction force caused by the transpiration which occurred by the regular opening and closing of the stomata for exchange of gases.

there is difference between transportation of water and minerals and food is that the water and minerals in plants transported in only one direction that is upward where as food in plants can be transported everywhere and in each part.
