Seeds
--> Seeds contain a young,
developing plant embryo
 Seeds are covered with a
protective seed coat
 Inside is stored food that the
young plant uses as it begins to
sprout or germinate
 Seeds form from ripened ovules
after fertilization
2
Seed Germination
Early growth of plant
embryo
Begins when seed
absorbs water &
breaks seed coat
 Embryo uses stored
food of cotyledons to
begin growing
3
Parts of a Seed Embryo
 Primary root or Radicle
 One or two embryonic leaves called
Cotyledons
 Stem like portion below cotyledons
called Hypocotyl
 Stem like portion above
cotyledons called Epicotyl
4
5
Monocots …ONE cotyledon!
 Parallel
venation in
leaves
Flower parts in
multiples of 3
Vascular tissue
scattered in
cross section
of stem
6
Dicots… TWO cotyledons!
 Net venation
in leaves
Flower parts in
multiples of 4
or 5
 Vascular
tissue in rings
in cross section
of stem
