3. Zygote develops into the
embryo part of the seed

Seed Dispersal
• As seed develops, the ovary changes into
a fruit
– a ripened ovary and other structures that
enclose one or more seeds
Types of Angiosperms
• Divided into 2
major groups
– Monocots
– Dicots
EQ: How do I name the
types of angiosperms
and list the
characteristics they
share?
Monocot
• Have one seed leaf
• Flowers usually have either three petals or
a multiple of three petals
• Long slender leaves with veins that run
parallel to each other
• Bundles of vascular tissue is scattered
throughout stem
EQ: How do I name

Dicots
• Produce seeds with two leaves
• Flowers have 4 or 5 leaves or multiples of
these
• Leaves are wide with veins that branch off
from one another
• Bundles of vascular tissue bundled
together
