What characteristics do living things share?
Living things that exist on Earth may seem very different, but they are alike in several ways.
There are five characteristics that all living things share. * Made of cells, * Respond to their environment,
* Reproduce, * Use Energy, * Grow & Mature

3. What Characteristics do Living Things Share?
As you read p 6-9, fill in details under each characteristic
Made of Cells
Respond to Environment
Reproduce
Use Energy

Living Things are Made of Cells
made of one or more cells.

What characteristics do living things share?
Unicellular organisms are made up of only one cell.
Multicellular organisms are made up of more than one cell.
Some multicellular organisms have trillions of cells that usually perform specialized functions.

Unit 1 Lesson 1 Introduction to Living Things
What characteristics do living things share?
Living Things Respond to Their Environment
Have the ability to sense a change and respond to that change
A change that affects the activity of an organism is called a stimulus.
A stimulus can be gravity, light, sound, a chemical, hunger, or anything else that causes an organism to respond in some way.

7. Stasis – standing still
P 7
Unit 1 Lesson 1 Introduction to Living Things
What characteristics do living things share?
Living Things Respond to Their Environment
Conditions inside an organism’s body must stay relatively constant.
Chemical reactions keep an organism alive and can happen only when conditions are exactly right.
An organism must maintain stable internal conditions to survive. This maintenance is called homeostasis.

Homoios – similar
Stasis – standing still

Unit 1 Lesson 1 Introduction to Living Things
What characteristics do living things share?
Living Things Reproduce
Organisms make other organisms
They pass copies of all or part of their DNA to their offspring.
DNA, or deoxyribonucleic acid, is the genetic material that controls the structure and function of cells.
DNA is found in the cells of all living things.
Offspring share characteristics with their parents because they receive DNA from their parents.

What characteristics do living things share?
Living Things Reproduce
Two Parents
Offspring share characteristics of both parents
Offspring revives DNA from both parents
Most Plants and Animals
One Parent
Offspring are IDENTICAL to the parent
Exact copy of parent DNA
Most Unicellular organisms
Some plants/animals

Unit 1 Lesson 1 Introduction to Living Things
What characteristics do living things share?
Living Things Use Energy
need energy to carry out the activities of life.
Energy allows organisms to make or break down food, move materials into and out of cells, and build cells.
Energy also allows organisms to move and to interact with each other.

12. What characteristics do living things share?
P 9
Unit 1 Lesson 1 Introduction to Living Things
What characteristics do living things share?
Living Things Use Energy
convert energy from the sun into food, which they store in their cells until they need to use it.
must eat other organisms to gain energy.
break down decaying material

Living Things Grow and Mature
All living things grow during some period of their lives.
unicellular organism: gets larger and then divides, forming two cells.
multicellular organism grows: the number of cells in its body increases, and the organism gets bigger.
They also develop, change and mature
Infancy  Childhood  adolescence  Adult
Pass through different stages of development
Young Tadpole  older Tadpole  Frog
Egg  Larva  Caterpillar  Pupa  Butterfly

Made of Cells
Smallest unit of life
1 cell = unicellular
more than 1 cell = multicellular
Specialized Functions
Respond to Environment
stimulus --> response
internal and external stimuli
maintain homeostasis - stability
Reproduce
pass copies of DNA to offspring
Sexual = 2 parents
share characteristics of both parents
Asexual = 1 parent
binary fision
budding
exact copy of parent DNA
Use Energy
some make own food
Photosynthesis
Producers
some orgamisms eat other orgainisms (plant or animal)
Consumers
fungi break down dead or decaying organisms
Decomposers
Grow and Mature
unicellular - grows larger and divides into 2
Infant --> childhood --> adult
metamorphosis
egg --> larva --> pupa --> adult

Stayin’ Alive
What do living things need to survive?
Almost all organisms need water, air, food, and a place to live in order to survive.

16. What do living things NEED for survival?
p 10 - add details (bubbles) around each characteristic
Needs for survival
A place to live
food
air
Water

18. Organisms often compete for food, water, and the best place to live.
Unit 1 Lesson 1 Introduction to Living Things
What do living things need to survive?
Cells are mostly made of water, and most chemical reactions in cells require water.
Air contains gases that organisms need to survive.
Cells use oxygen in air to release energy from food.
Organisms such as plants use the carbon dioxide in air to make food.
A place to live protects organisms from harm and contains the other necessities of life.
Food provides organisms with the energy and nutrients that they need to survive.
Organisms often compete for food, water, and the best place to live.

19. How do living things get food?
P 11
Unit 1 Lesson 1 Introduction to Living Things
How do living things get food?
Food gives living things the energy and nutrients they need to perform life processes:
allows cells to divide and allows the organism to grow and develop
Nutrients include carbohydrates, lipids, and proteins.
Fruits, vegetables, and grains provide carbohydrates.
Nuts and fats provide lipids.
Meats, nuts, and vegetables provide protein.

20. How do living things get food?
P 11
Unit 1 Lesson 1 Introduction to Living Things
How do living things get food?
Producers, such as plants and algae, make their own food.
Plants and algae use energy from the sun to make food.
Photosynthesis
Consumers, such as deer, mice, and eagles, eat other organisms.
Decomposers, such as worms and fungi, break down dead organisms or wastes to get food.
They return nutrients that plants can use to the soil.

21. Visualize it 13 & 14 Organism Classification Way of getting food
Water
They get water from food that adult eagles bring to them.
Air
Food
Place to live
Young eagles breathe air.
Adult eagles bring food like fish to the young eagles.
Adult eagles build a nest high in trees to protect young eagles from animal that could harm them.
