Cells have chloroplasts. The green chlorophyll traps light energy.

Cells have chloroplasts. The green chlorophyll traps light energy. 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. Thin, flat leaves catch light. They have a large surface area.

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

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

  4. Leaves do not overlap.

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

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

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

  8. Evergreens keep their leaves all year.

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

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