Seeds and
Plants
What is a seed and how does
it grow?

A seed is the part of the plant that produces
the next plant. Think of it like a baby or a
pre-baby—an embryo; it grows from a small
creature into an adult than can then produce
more seeds aka babies/embryos.

Seeds need warmth and moisture to grow.
They do not need light. They also need
food. Depending on the species, the seed’s
energy comes from either coytledon or
endosperm, both things that provide
essential nutrients for the seed to jumpstarts
its young life.
Seed becomes Plant!

Once the seed sprouts and emerges from
the soil it starts the process of
photosynthesis-turning the sun’s energy into
food it can use to grow.
