Explain how the process of cellular respiration and the process of photosynthesis complement each other

Cell Respiration and Photosynthesis

2.2

Cell Respiration and Photosynthesis

Definition

Respiration can be divide into external respiration and internal respiration.

External respiration: involves exchange of gases between the organism and environment

Cell respiration: oxidation process and break down glucose

Cell Repiration

Glucose + Oxygen \(\rightarrow \) Carbon dioxide + Water + Energy

Photosynthesis

Carbon dioxide + Water \(\begin{aligned} &\text{Light energy}\\ &\quad\longrightarrow\\&\small\text{Chlorophyll} \end{aligned} \) Glucose + Oxygen

Cell respiration	Photosynthesis
Occur in mitochondria	Occurs in chloroplast
Process to release energy	Process to absorb energy
Uses chemical energy in food	Uses energy from light
Occurs in humans, animals, plants and microorganisms	Occurs in plants and microorganisms
Breaks down glucose to produce energy	Synthesises glucose
Uses glucose and oxygen to produce carbon dioxide, water and energy	Uses carbon dioxide and water to produce oxygen and glucose
Occurs at all times	Occurs only in the presence of light

The process of cell respiration and photosynthesis complement each other:

Plants produce glucose and oxygen
All organisms use glucose and oxygen during respiration
All organisms produce carbon dioxide and water
Plants use carbon dioxide and water during photosynthesis
