Plant Growth
Plants are able to grow throughout their lifetime due
to the presence of undifferentiated tissues called
meristems.

Reproduction in Angiosperms
Apical meristems add primary growth and cause the
stem to increase in length. Apical meristems are
located at the tips of stems and roots.
Lateral meristems add secondary growth and cause
the plant to increase in girth.

Two Common Types of Germination
Structure of the Mature Seed
Germination begins
with imbibition, the
uptake of water by
the dry seed.
Rupturing of the seed
coat triggers
metabolic changes
that allow the plant
embryo to resume
growth.
A seed consists of a
dormant plant
embryo, surrounded
by its food supply
(cotyledons,
endosperm, or
both). The seed is
surrounded by a
hard, protective seed
coat.
