| The basic function of leaves | Leaves capture the sun‘s energy and carry out the food – making process of photosynthesis |
| What is the difference between photosynthesis and cellular respiration? | Photosynthesis stores energy, and cellular respiration releases it |
| The three ways a seed can be dispersed | When animals eat, the seeds inside the fruit pass through the animals digestive system and are deposited in new areas. Other seeds are enclosed in barb-like structures that hook onto fur or clothing. Some are taken by the wind. |
