3.6 understand how germinating seeds utilise food reserves until the seedling can carry out photosynthesis

Inside a developed seed, there is a food store. When the seed starts to germinate, it gets the glucose needed for respiration from its food store - this means it can respire, meaning it has enough energy to grow. A plant will begin to photosynthesise once its leaves will begin to grow, this is when it stops using its food store.
