1 When plants use energy from sunlight to make nutrients, we call this process 2 This process mainly takes place in the cells of the plant’s 3 These cells contain a green substance called , which absorbs the Sun’s energy. 2

Tick the sentences that are true.   1 Photosynthesis only takes place inside the plant’s stem.  2 T  he cells of a plant contain a green substance called chlorophyll that absorbs the Sun’s energy.   3 Plants respire continuously to absorb oxygen.  4 P  lants expel oxygen through their roots during photosynthesis.

Find the words in bold below in the word search. 1 Photosynthesis produces oxygen as a waste gas. 2 P  lants expel oxygen, water vapour and carbon dioxide through little holes in their leaves called stomata. 3 P  lants use oxygen to transform the carbohydrates contained in phloem sap into energy to grow.
