D. Playing video games
Question 4
4.
What are the raw materials of photosynthesis?
carbon dioxide and water
oxygen and water
carbin dioxide and sugar
oxygen and sugars
Question 5
5.
Which of the following is not true about the products of photosynthesis?
Some of the sugar is made into other compounds, such as cellulose.
