→Key Stage 3
Most [[Oxygen]] on Earth is made by [[algae]] '''photosynthesising''' in the oceans.
==Key Stage 4==
===Meaning===
'''Photosynthesis''' is the process that takes place in the [[Chloroplast|chloroplasts]] in [[Cell (Biology)|cells]] which uses [[Carbon Dioxide]] and [[Water]] to produce [[Glucose]] and [[Oxygen]] using the [[energy]] [[Transfer|transferred]] to the [[organism]] by sunlight.

===Rate of Photosynthesis===
*[[Light]] - The more [[light]], the faster [[photosynthesis]] can happen.
*[[Water]] - [[Photosynthesis]] needs [[water]]. If there is not enough [[water]] [[photosynthesis]] will slow down.
*[[Temperature]] - [[Photosynthesis]] works best at 30[[°C]]. Too much colder or too much warmer and [[photosynthesis]] will slow down.
*[[Carbon Dioxide]] - [[Photosynthesis]] needs [[Carbon Dioxide]]. The more [[Carbon Dioxide]], the quicker [[photosynthesis]] can happen.
