Types of Reproduction

Types of Reproduction
Reproductive System Basics

• Two Types of Reproduction
• Asexual
• A single parent produces offspring genetically
  identical to itself.
• Single-celled organisms.

BACTERIA
Identical Offspring
Original parent
2

• More uniform offspring

3

• Requires one parent

4
REGENERATION occurs when part of an organism
grows to form other organisms that are often
still connected to the original organism.
5
FRAGMENTATION occurs when the body of the parent
breaks into distinct pieces, each of which can
produce an offspring.
6
Planaria reproduce by fragmentation and
regeneration
7
Starfish reproduce by fragmentation and
regeneration
8

• BUDDING occurs when a small part of the parent's
  body separates from the rest and develops into a
  new individual, eventually becoming an
  independent organism.

9
Yeast a type of bacteria that you use in bread.
Reproduce by budding.
10
Hydra found in lakes and ponds. Reproduce by
budding.
11

• BINARY FISSION occurs when a cell simply grows
  larger, copies its DNA in genes and chromosomes,
  and then forms a cell membrane down the
  mid-section of the cell to form 2 new 'daughter'
  cells.

12
Amoeba reproduces by binary fission.
13
Bacteria reproduces by binary fission.
14
Reproductive System Basics
Two Types of Reproduction Sexual Offspring is
produced by combining the genetics of two
parents. Multicellular organisms.
15

• Requires two parents

16

• More genetic variation

Asexual vs. Sexual Reproduction
Asexual Reproduction
Sexual Reproduction
18
Asexual vs. Sexual Reproduction
A single parent cell produces offspring that are
exactly like the parent.
Two parent cells join together and develop into a
new individual
Living things make other living things like
themselves
The new individual has the exact same traits as
the parent
Asexual Reproduction
Sexual Reproduction
The new individual shares traits from both
parents
All organisms must reproduce in order for their
kind to survive
Most single celled organisms
Most animals
Humans
Strawberry Plants amoebas coral
19
Asexual or Sexual ?
Involves two parents.
20
Asexual or Sexual ?
Creates Genetically Diverse Offspring
21
Asexual or Sexual ?
Creates Genetically Identical Offspring
22
Asexual or Sexual ?
Ex Animals
23
Asexual or Sexual ?
Single Celled Organisms
24
Asexual or Sexual ?
Involves only one parent.
25
Asexual or Sexual ?
Example Bacteria, Hydra a Starfish
26
Asexual or Sexual ?
Multicellular Organisms

CLASSIFYING ORGANISMS

• Objective Classify the following illustrations
  as either SEXUAL or ASEXUAL organisms.

Title Albino Spider Alligator
ALBINO lack of normal pigments in the skin that
give the organism its natural color. It is a
genetic abnormality.

Title Budding Hydra
39
Title Aye-Aye(From Madagascar)
Unique Characteristics the Aye-Aye has long
fingers that tap on the tree branch only to spear
its prey. It has big ears to detect movement of
its prey at night inside the tree.
