Do all plants come from seeds?
Some plants do not come from seeds. They come from spores.
A spore is usually made up of one cell—a tiny bag of living jelly that
you would need a microscope to see. Spores have a covering on the
outside to protect them.
Spores grow in little sacks on the leaves and stems of mosses, ferns,
horsetails, and some other plants. There are usually a great many spores
in each sack, but very few of the spores will become new plants.
These spores are blown into the air and float away on the wind. Out of
millions of them, only a few come down where there is the right kind of
soil, water, and light they need if they are to grow.
A spore grows into a tiny green plant that is nothing at all like the
plant the spore came from. But this tiny plant makes cells that join
together. These cells then grow into plants that are just like the plant
the spore
