Today in science we tested a bean seed and a potato for starch to answer the question, “Do plants contain the food that organisms need?” Below, is my scientific explanation that explains what we learned and discovered from our lab today.

Claim:
Plants contain the food that organisms need.

Evidence:
If you ever eat anything other than a plant what you ate somehow got its energy from plants. We tested potatoes and seeds for starch using iodine and the potato did have starch and the seed didn’t.

Reasoning:

I know that the potato is a plant that other organisms need because it has starch.
