Mode of reproduction that does not involve the use of gametes or sex cells
Asexual Reproduction
Mode of reproduction that involves the use of gametes or sex cells
Sexual reproduction
A type of asexual reproduction involving the division of the body into two
or more equal parts
Fission
A type of asexual reproduction where the body breaks into two
or more parts, with each fragment capable of becoming a complete individual
Fragmentation
A type of asexual reproduction where a new individual arises as an
outgrowth (bud) from its parent, develops organs like those of the parent, and
then detaches itself.
Budding
A type of asexual reproduction where a new individual forms from
an aggregation of cells surrounded by a resistant capsule or spore, which later
on germinates
Sporulation
Fusion of similar gametes which are usually motile.
Isogamy
Fusion of dissimilar gametes. In oogamy, a large immotile gamete, the egg, is fertilized by a small motile gamete, the sperm.
Heterogamy
This type of sexual reproduction involving the union of gametes from two genetically different parents.
Bisexual reproduction
An individual with both male and female reproductive tissues.
Hermaphrodite
TYPES OF ASEXUAL
Fission
Budding
Fragmentation
Sporulation
Example of fission
Paramecium
Example of Budding
Hydra
Examples of Fragmentation
Spirogyra or Oedogonium, and a detached starfish arm growing lost parts
TYPES OF UNION OF GAMETES
Isogamy
Heterogamy
Chlamydomonas producing gametes or Spirogyra undergoing conjugation as example;
Isogamy
animal sperm and egg as examples
Heterogamy
SPECIAL TERMS OF SEXUAL REPRODUCTION
Bisexual reproduction.
Hermaphrodites
Examples are in humans, and papaya among others.
Bisexual reproduction
barnacles; worms
Hermaphrodites
Offspring is genetically identical to the parent, which means the offspring is a
CLONE of the parent.
ASEXUAL REPRODUCTION
Generally, it produces variation in the offspring because this results in the
recombination of genomes from the parents’ gametes.
