Asexual Reproduction in Animal

Open Ended

Describe the appearance of the hydra.

HYDRA

A new hydra starts as a “bud” forming on the side of a hydra's body; it grows and eventually breaks away as a clone of the original.

Open Ended

How does the hydra move and what are the ''buds'' for?

​Movement and Budding

1. The hydras usually move by looping and somersaulting, by attaching the tentacle ends and pulling themselves along. When there is an insufficient supply of oxygen, hydras move to regions of higher oxygen content.

2. The small bud then receives its nutrition from the parent hydra and grows healthy. Growth starts by developing small tentacles and the mouth.

Multiple Choice

Is hydra an animal or plant?

• Animal

• Plant

Multiple Choice

what type of reproduction is the hydra?

• Asexual

• Sexual

Asexual- only a single organism is involved.

​There are different processes involved in asexual reproduction:

1. Fission or binary fission

2. Budding

3. Regeneration

Multiple Choice

Which asexual reproduction is mostly observed in bacteria and amoeba?

• Fission/Binary Fission

• Budding

• Regeneration

​Fission/Binary Fission

1. The simplest form of asexual reproduction

2. A parent splits into two identical daughter cells

3. Bacteria, amoeba, and sea anemone

FISSION/BINARY FISSION

Multiple Choice

What type of asexual reproduction where the new individual animal is an outgrowth of cells of the parent organism?

• Budding

• Fission/Binary Fission

• Regeneration

​Budding

1. Is growing a new individual from a bud

2. Sponges, hydra, flatworms

3. The bud enlarges, takes the form of the parent and then breaks off as a new individual

​BUDDING

Multiple Choice

What type of asexual reproduction refers to the an animal divides into one or more fragments?

• Budding

• Fission/Binary Fission

• Regeneration

1. Flatworms, marine worms

2. A broken part is replaced by regenerating the missing part (like starfish and earthworm)

​Regeneration

Open Ended

If these organisms reproduce asexually, what do you think are the advantages and disadvantages of this type of reproduction in the environment?

(List at least 3 disadvantages and 3 advantages)
