All plants undergo sexual reproduction (two
partners). When the sperm and egg come
together you get a zygote / baby plant.

Gymnosperm: Non-flowering, seeds usually
arranged on a cone.

“This is one
big cone, It
must be one
of the largest
ever!”
Wow!,
That’s a
big cone!
“I agree.”
“Why would
you ever
need a cone
that big.”
“I could sure
go for a
sno-cone.”
Look at the
size of this
cone.

Cone

Angiosperm: Flowering, covered seed,
produce seeds enclosed in a fruit /ovary.
