Photosynthesis
mechanism by which organisms use CO2 (carbon dioxide) + H2O (water), in the presence of sunlight to make sugars (C6H12O6 = glucose) + O2 (oxygen gas, released)
Xylem
conducting tissue in plants, moves water from roots to leaves
Phloem
conducting tissue in plants moves sugars and other nutrients from leaves to other parts of plant
Cephalization
a concentration of sensory structures in anterior region of the body
Radial Symmetry
A body plan in which identical parts are arranged in a circular fashion around a central axis, sea stars

a body plan where the organism has mirror-image right and left sides
