Asexual reproduction allows offspring to form from a single parent without fertilization. It is common in plants, single-celled organisms, and simple animals. There are several mechanisms for asexual reproduction including budding, parthenogenesis, gemmules, and fragmentation. Hydras reproduce through budding where a small bud grows from the parent's body and detaches to form an independent organism. Corals similarly bud but offspring do not detach and instead form groups. Sponges release internal gemmules that develop into new organisms.

1. ASEXUAL REPRODUCTION
in
ANIMALS

2. Not all animals undergo sexual
reproduction, doesn’t require sperm
and egg cell. Ex: jellyfish

3. Asexual Reproduction
 Offspring comes from only one parent without union
of sex cells
 The offspring is called clone (has traits and
characteristics that are very identical to that of the
parent)
 Common among plants, single-celled organisms, and
simple animals that do not need sex cell to reproduce
 EX: hydras, jellyfish, corals, and sponge

4. Different Mechanisms in Asexual
Reproduction
1. Budding
2. Parthenogenesis
3. Gemmules
4. Fragmentation

5. PROCESS OF HYDRA’S
REPRODUCTION
- Parent hydra grows a bud from its
body
- Small bud enlarges and forms
tentacles or slim, flexible limbs
used by animals to move, hold,
and feed
- Newly formed organism detaches
from the parent hydra and
becomes independent.
- Allows organism to
grow our of the
body
- Example: hydra,
corals, and yeast

6. PROCESS OF CORAL’S
REPRODUCTION
Corals – tiny sea animals
that produce outer
skeletons that
resembles shells.
- Unlike hydra, newly
produced coral does not
detach itself from the
parent and it leads to a
formation of groups of
corals on the ocean
floor.
PROCESS OF YEAST’S
REPRODUCTION
- Fungi is a species of
fungi that reproduce
exactly the same with
hydra.

9. Komodo Dragons
- Normally find mates to
reproduce BUT when there is no
male during the cycle and the
female is in good shape to
produce healthy eggs, they can
undergo this parthenogenesis
- An egg cell that does
not need to be
fertilized by the sperm
cell
- Egg cell produced by
the female develops
into a new individuals
- Ex: komodo dragons,
hammerhead, shark,
mole salamander, and
bees

MOLE SALAMANDER
BEE
HAMMERHEAD SHARK

11. SPONGE
- Adult sponge releases its
gemmules in water
- Gemmules get nutrients from
the surroundings and develop
into a new organism.
- Internal buds or
structure found in the
sponge that can
develop into a new
organism
- Ex: sponge – a marine
organism that its body
is covered with pores
that allow water to
flow.

14. SEA STAR
- When part of it breaks off
due to strong current
- It begins to grow on its own
into an adult with exactly
the same characteristics of
the parent.
- Happens when a piece
of an organism breaks
off
