1. Flowering plants grow from seeds.
Seeds contain a tiny, dormant embryo plant, together with stored food reserves. The seed
is surrounded by a tough coat which protects it. In Britain, seeds vary in size from the size of a grain of salt
(Heather, Foxglove) to a large marble (Horse Chestnut). Acorns (right) are somewhere in
between. The bigger the seed, the more food reserves it contains. |
