1. 1 Cells have chloroplasts. The green chlorophyll traps light energy.

2. 2 This is the inside of a leaf. The top cells have many chloroplasts and no gaps. Air spaces let gases move around. Veins bring water to the cells.

3. 3 Thin, flat leaves catch light. They have a large surface area.

4. 4 Leaves do not overlap.

5. 5 Guard cells let in gases through pores called stomata but can close to stop the leaf wilting.

6. 6 Stiff, woody stems hold leaves high to get light.

7. 7 Climbing plants twist around objects or have special “roots” along their stems. They climb up to get light.

8. 8 Evergreens keep their leaves all year.

9. 9 Woodland plants grow early before trees block the light.

10. 10 Water plants have gas filled structures to float near the surface where most light is.
