After about two weeks of letting the plants mature it

This preview shows page 4 - 7 out of 8 pages.

After about two weeks of letting the plants mature it is time to pollinate them, this is the second part. This is done with a pollination stick (we used a small paint brush), We used this to take pollen from the flower of one plant to the flower of another. Then the sticks are saved to pollinate again in two then in four days. After the third pollination you should clip off all of the smaller buds that are unopened. You must remove these unopened buds every few days for the next two weeks. Now the third stage, this is the part to harvest the plant seeds, about 21 days after the day we pollinated the plants. Then you must remove the seed pods from each of your plants. You must do this separately for each of the different plant seed pods so that the different types of seeds do not become mixed. The fourth step of this full procedure is the germination of the collected seeds. The seeds for 8.2 and 8.3 are to be germinated in quads using the same procedure that we used to originally plant the seeds there first time so that we can observe the leaves and full plants then produced.
Fast Plants Lab Report For 8.1 you will first need to moisten a piece of filter paper in a petri dish labeling the dish with 8.1, your group name, date and seed type. Next place the petri dish and tilted on an end in a water reservoir adding about 2cm of water. Then carefully place the dish under a light bank and in about 48-96 hours it is visible to observe the seedlings and record the phenotypes in the appropriate table. Lastly you must tabulate the results and preform a chi-square analysis and test on the class results. RESTULTS In the first experiment we had to observe the inheritance of the Anthocyanin Gene. The data we collected is represented in the table below. Anthocyanin was present in 8 plants, there were no plants without Anthocyanin. Table 1: Anthocyanin Inheritance Phenotypes of F1 Anthocyanin Present Anthocyanin Absent Total Number Group Data 8 0 8 The second section of the experiment, we observed the inheritance of the plant color. This gave us F2 generation with a total of 9 plants. There were only 2 with No Anthocyanin and only 7 plants with Anthocyanin preset.
