Where do Seeds Come From?

The plants that feed us, and that feed other animals on the planet, have all grown from seeds. Where do these seeds come from, and who owns them?

Where do Seeds Come From?

Maybe you have planted a seed before and watched it germinate and grow. Where did this seed come from? Perhaps you bought it in a packet, or maybe you found it as part of a plant.

Seeds are the way that flowering plants are able to reproduce. The seed is the beginning of a new plant, in the way that an embryo is the beginning of an animal. Fruiting plants often produce their seeds in the middle of their fruits. You may have noticed them inside an apple or orange.

Without seeds, there would be no plants and without plants, there would be no seeds. For more information on seed growth, see our lesson plan on plant reproduction.

Where did the first seed come from? – Alice, age six, Beverley, UK

Hi Alice. This is a clever question. As I’m sure you know, plants use seeds to spread their young and make new plants. But plants haven’t always used seeds to do this. Seeds came together bit-by-bit over a really long time, as plants evolved.

To understand how this happened, you need to know that all living things change slowly over time, to get better at surviving in their environment – this process is called evolution.

Here’s how it works: when a living thing has a feature which works well, it will be able to live longer and have more young. These young will probably have similar features, thanks to their parents.

Plants started using seeds to spread their young somewhere between 385m and 365m years ago. Before seeds existed, plants had other ways of doing this.

Back then, most plants used spores. Some plants today, such as algae, mosses and ferns, still do. You might have spotted the tiny brownish dots on the underside of fern leaves – these are spores.

Spores are different from seeds in a few ways. A spore is made of just one part – a single cell – while a seed contains many cells, each with different jobs to do.

Another difference is that spores only have one parent plant, while seeds have two.

This means that, after a seed starts sprouting, it can grow into a plant, just like its parents.

But spores have to work a bit harder: once they’ve travelled away from their parent plant, they grow into a little green plate of cells, which scientists call a “gametophyte”. Then, two gametophytes must join together, before they can grow into a plant.

It’s easier for gametophytes to join together when its wet – and that’s why plants that use spores usually need to grow in wet places.

For example, horsetails are a very ancient type of plant, which like to grow along lakes, rivers and ponds: they have very strange spores with four “legs” which help them to move and travel further away.

The first seed

Scientists believe that an extinct seed fern, called Elksinia polymorpha, was the first plant to use seeds.

This plant had cup-like features, called “cupules”, that would protect the developing seed. These cupules grew along the plant’s branches.

Today, plants with seeds do things a little differently. There are two main types: “angiosperms” and “gymnosperms”.

Angiosperms are flowering plants – their seeds develop inside of fruit, like apples, tomatoes or even rose hips or holly berries.

Gymnosperms, such as pine trees, grow their seeds inside a hard cone.

The upside of seeds

Seeds have evolved because they are better at helping plants to survive than spores are. For example, seeds contain a food source to help the new plant grow.

They also have a hard coat, which helps them to live longer in different conditions: this means plants with seeds can life in lots of different places, from hot, dry deserts to cool, rainy places.

Seeds are so good at helping plants to spread their young that most plant species on Earth today use seeds.
