What is Asexual Reproduction?

1
What is Asexual Reproduction?
A way to reproduce where offspring are created
from a single parent, and inherit the genes of
that 1 parent only
2
Binary Fission

• Involves a one celled organism.
• 1 parent cell 2 new daughter cells.
• The cells become an exact replication of each
  other.

Sexual Reproduction in Plants
Angiosperms and Gymnosperms reproduce sexually by
producing___Seeds_______ Do plants have Sperm
and Eggs? ____YES__________ A ZYGOTE is
created when a plants sperm and egg
_____UNITE____ A zygote eventually becomes a
EMBRYO as more cell division occurs

Budding

• This is when a child grows out of the parent.
• The child is smaller than the parent
• Genetically identical
• The parent and child could stay connected and
  form a colony, or separate.

5
Spores

• Spores (single celled structures) contain
  genetically identical material to that of their
  parents
• Examples are
• bread mold, mushrooms, mosses and ferns.

Sexual Reproduction in Plants
Although some plants (ferns and mosses) reproduce
ASEXUALLY through spores, a lot of the
Angiosperms (flowering plants) and Gymnosperms
(cone-bearing plants) produce SEXUALLY

• With a partner
• Take a tulip
• Using a scalpel, cut the tulip exactly in half
  without destroying it
• Using the tools in your kit, see if you can
  identify these structures (also pg 33 of
  textbook)
• Ovary
• Pistil
• Stamen
• Anther/Filament
• Petal
• Stigma
• On blank paper, complete a drawing (at least
  15cm) of your tulip dissection
• Points awarded for neatness, quality, and
  labeling of all structures
• Define the following on the back of your page
• Zygote, Pistil, Stamen, Ovule, Pollen Tube,
  Embryo, Cotyledons
