Two types:

Production of new organisms or cells (healing, growing)
Two types: Sexual reproduction: cells from two
different parents unite to produce the first cell of the new organism; new mix of genetic material

Two types: Sexual reproduction: cells from two
different parents unite to produce the first cell of the new organism; new mix of genetic material
Asexual reproduction: new organism has a single parent; May result when a piece breaks off from the parent organism or when the parent organism divides in two

Reproduction involves the replication of DNA molecules to pass on hereditary information

Reproduction involves the replication of DNA molecules to pass on hereditary information
This directs the structure of of the cell and its metabolism.

materials and energy. Metabolism: combination of
chemical reactions through which an organism builds up or breaks down materials as it carries out its life processes

All organisms take in selected materials from their environment; how they do so varies

Characteristics of Living ThingsCharacteristics of Living Things Living things respond to their
environment.
Characteristics of Living ThingsCharacteristics of Living Things Living things respond to their
environment. Stimulus: signal to which an
organism responds
Characteristics of Living ThingsCharacteristics of Living Things Living things respond to their
environment. Stimulus: signal to which an
organism responds External: come from the
environment outside the organism; ex. Light, temperature (plant roots respond to gravity by growing down)

responds External: come from the environment
outside the organism; ex. Light, temperature (plant roots respond to gravity by growing down)
Internal: come from the environment inside the organism; ex. Sugar glucose (if it’s low, your body will respond by making you feel hungry)

Characteristics of Living ThingsCharacteristics of Living ThingsLiving things maintain a stable internal environment.
Characteristics of Living ThingsCharacteristics of Living ThingsLiving things maintain a stable internal environment. Homeostasis: keeping a stable internal environment
Characteristics of Living ThingsCharacteristics of Living ThingsLiving things maintain a stable internal environment. Homeostasis: keeping a stable internal environment
Ex. When your body temperature goes too low, you shiver; muscle movement creates warmth
Characteristics of Living things
Living things have methods for eliminating waste

Characteristics of Living things
Living things have methods for eliminating waste Living things must have a method for eliminating bi-products or waste products
Characteristics of Living things
Living things have methods for eliminating waste Living things must have a
method for eliminating bi-products or waste products
Ex. In humans, exhaling, defecation, urination
Characteristics of Living thingsLiving things are adapted.
Adaptations: modifications that make an organism suited to its way of life and environment
Occur through evolution via natural selection When a new variation arises that allows certain
members of the species to capture more resources, these members tend to survive and to have more offspring than the other, unchanged members.
Over time, the new variation becomes more prevalent in the population.
Let’s practice…Our cat had kittens yesterday.
Our dog was much smaller when it was a puppy.
When you look at a piece of a plant leaf under a microscope, you see many smaller divisions.
My children look a lot like their father.

More practice… I sweat a lot after football practice.
It helps me cool down.
My cat ran under the porch when his car pulled into the driveway.
Mrs. Lynch, can I go to the bathroom?
I am always tired after I run a mile.
