Living or not

Since we first planted the seeds, we have noticed the seeds have grown a lot since then. We can see they're living because they take in water and they've changed a lot. When we first put them in they were actual tiny seeds and now these seeds have sprouted, made roots, and have caused a stem with leaves to grow. We can measure if they're alive by checking and measuring their growth in size and weight every other day. This will show and convince us that the plants are alive because we will see if they're actually getting growing or if they're living. Once the caulifowers start coming out of the plant it will be proven that the plant is alive.
