Lesson 1: Asexual Reproduction

Question 1

Asexual
Reproduction

Answer 1

The formation of a new but
identical individual from a
single organism.

Question 2

Types of Asexual
Reproduction :1. Binary Fission

Answer 2

A parent cell divides so that each new cell contains a complete set of DNA identical to that of the parent.

Occurs in unicellular organisms that do not have a true nucleus.

Ex. Bacteria

Question 3

Types of Asexual
Reproduction :2. Budding

Answer 3

A bud grows on the parent organism.
The bud grows for a while and
eventually breaks away forming an
independent organism.

Occurs in invertebrate animals such
as sponges and hydra

Question 4

Types of Asexual
Reproduction :3. Sporulation

Answer 4

The parent organism produces spores. Spores are stored in the sporangium until they are mature
and ready to be dispersed. Spores can grow into a new individual through mitotic cell division

Occurs in bread mold.

Question 5

Types of Asexual
Reproduction :4. Regeneration

Answer 5

An organism divides in half and regenerates the parts it is missing. New limbs can also be grown this
way.

Occurs in invertebrates such as planarians and sea stars.

Question 6

Types of Asexual
Reproduction :5. Parthenogenesis

Answer 6

Growth and development of embryos
occurs without fertilization.

Occurs in Daphnia, which under ideal
conditions use parthenogenesis to
reproduce rapidly.
