13. What is Germination? • Early Growth Stage of Embryo

14. What role do leaves play in plant? • Leaves capture the sun’s energy and carry out the food making process of photosynthesis

15. Structure of leaf

16. What are the functions of stems? • Carry substances between the leaves and roots • Support the plant and hold up the leaves • Store food.
