"Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process."
Segmentation allows for a greater degree of variety among species
The concept of segmentation relies upon the ability for organisms to duplicate organs and structural elements, such as arms and legs
The ability to divide functions into different portions of the body allows an organism to perform increasingly complex activities and use different segments to perform varying functions
For example, humans consist of heteromeric segmentation, in which each segment differs from another and fulfills a specific role
Homomeric segmentation refers to segments that contain similar elements, such as with the segments in an Errantia, a type of worm
