Question

the overall purpose of cellular respiration is to produce oxygen for living things atp for cells glucose for food water for plants

Explanation:

Cellular respiration is a metabolic process. It breaks down glucose (or other organic molecules) in the presence of oxygen (aerobic respiration) or without oxygen (anaerobic respiration in some cases). The key goal is to generate adenosine - triphosphate (ATP). ATP is the energy - currency of the cell. It provides energy for various cellular processes such as active transport, muscle contraction, and biosynthesis.
Oxygen is consumed (not produced) in aerobic cellular respiration. Glucose is broken down (not produced) during cellular respiration. While water is a by - product of aerobic cellular respiration (from the electron - transport chain where oxygen acts as the final electron acceptor), the main purpose is ATP production. And the process is not specifically about providing water for plants.

Answer:

ATP for cells
