How a Plant Is Built, and What Each Part Is For
Finish this and you can look at any plant and say what you are seeing — not by recalling labels, but by asking what job each part has to do and where that job forces it to sit. It opens on the whole plant, where four parts answer four different problems, then zooms into the one part that is not keeping this plant alive at all, taking a flower apart to follow how a seed gets made. The last part follows that seed: five steps from dormant to feeding itself, including the one step almost everybody guesses the wrong way round. The order closes a circle on purpose — the third part builds the plant the first part took apart.

What Are the Parts of a Plant, and What Does Each One Do?
A plant is not one thing doing one job — it is four parts, each solving a different problem. Learn what roots, stem, leaf and flower each do, then label a plant yourself in an interactive playground.
What Are the Parts of a Flower, and How Do They Make a Seed?
A flower is not decoration — it is the part of a plant whose job is the next plant. Learn what the petal, sepal, stamen, stigma and ovary each do, then label a flower yourself in an interactive playground.
How Does a Seed Become a Plant?
A seed sits doing nothing for months, then grows in total darkness without being fed. Learn the five steps of germination, and why the root always goes down before the shoot goes up, then build the sequence yourself in an interactive playground.
