Botany picture #6: Pinus sylvestris

Pinus sylvestris (Pinaceae) seedling in Germany, 2012. A seed plant embryo consists of the primary root (radicle), the embryonic leaves (cotyledons) and a small stem connecting the two (hypocotyl). While flowering plants have only one or two cotyledons, conifers like this one have several.
