Taarika George Partner: Casey Watrous Due 11/1/04 Period F Are Seeds Alive? INTRODUCTION- It is not easy to tell whether seeds are alive or not. In this experiment, tetrazolium, which is a colorless chemical that turns pink when hydrogen is present, will be used to determine whether the seeds are viable. Another test will be performed called the germination test, which will also show if the seeds are viable. Performing this experiment will show if seeds are alive and what can affect them. The seeds will be divided into two types, type I and type II. Type I will be soaked in water and type II will be boiled. If seeds are tested through the tetrazolium and germination tests, then in the tetrazolium test, the seeds will turn pink and in the germination test the seeds will grow because seeds must be viable in order to produce their plant. The independent variable for type I is the soaking of the seeds. The independent variable for type II is the boiling of the seeds. The dependent variable for the tetrazolium test is the amount of seeds that turn pink in both type and the dependent variable in the germination test is the amount of seeds that germinate. RESULTS-
