| Explore | Pollen is really important in plant reproduction. Pollen is produced in the stamen and then transported to the stigma. Below the stigma is the ovary that holds the ovule. Once on the stigma, the pollen grows the tube which makes it to the ovule. This becomes the seed and the ovary becomes the fruit. |

| Research Question | Does the amount of sucrose affect pollen tube growth? |
| Predictions | We predict that 20% sucrose will make more pollen germinate. We think this because when we grew pollen tubes in 10% they grew so we think more sugar would mean more growth. |
| Experimental Design | We will have five dishes with five straws to go with them. We are going to have 5%,10%,15%,20% and 0%. That is the amount of sugar water we will be putting in each. At 0% we will just put water in it. We will be measuring the growth of the pollen. |

| About this Project | I really thought the experiment was unusual and thought provoking. The students did a good job of documenting with photos which they posted online. |
