Reproduction
Sexual and Asexual Reproduction
What is reproduction?

Reproduction is the
process by which
living things
produce new
individuals of the
same type.
Sexual Reproduction in Plants

A new individual results from the egg and
sperm cells from 2 parents.

Offspring may vary from the parents
depending on which traits were passed
on.

Allows for more genetic variation in
species.
Asexual Reproduction in Plants

Needs only one parent.

There is no fusion of egg or sperm and no
mixing of genetic material.

The offspring are genetically identical to
the parent (clones).
What are the types of asexual
reproduction?
Budding: offspring
grow out of the
body of the parent
(unequal division).
 Examples: hydra,
tapeworm, and
cnidarians.

What are the types of asexual
reproduction?

Binary Fission: the
body of the parent
divides through the
process of mitosis to
form 2 individuals.

Example: Amoeba,
euglena, bacteria
What are the types of asexual
reproduction?

Fragmentation: the
body of the parent
breaks into fragments
or pieces that grow
into new individuals.

Examples: flatworms,
planarians
What are the types of asexual
reproduction?

Regeneration: A piece
of the parent
becomes detached or
broken off and a new
piece can grow back.

Examples: starfish,
sea urchins, sand
dollars
What are the types of asexual
reproduction?
Parthenogenesis:
females produce
eggs, but these
develop into young
without being
fertilized.
 Examples: some
fishes and lizards,
several kinds of
insects

What are the types of asexual
reproduction?
Vegetative
Reproduction: a new
plant is grown from a
small piece of the
original plant, such as
leaves or stems
 Examples: potatoes,
strawberries, spider
plants

What are the types of asexual
reproduction?

Sporulation:
reproduction in which
spores are produced.

Examples: mold,
some fungi, and some
flowers
