Start

Learning Target: I can identify living and nonliving specimens by examining their characteristics and providing evidence to support my claims.

Review Do Now: What does it mean for something to be alive?

7 Characteristics of Life

Genetic Material/DNA

Growth and Development

Made of Cells

Responds to Stimuli

Metabolizes

Reproduce

Maintains Homeostasis

Made of Cells

All living things are made up of cells. Cells perform many functions to keep the organisms alive. They can be multicellular or unicellular.

Unicellular

Multicellular

Home

Reproduction

Create offspring/Make babies. Two types; sexual and asexual.

asexual

sexual

Home

Growth and Development

All living things grow and develop. Growth: increase in size and cell number. Develop: change in form or shape over time.

Home

Metabolism

All living things need energy to function. Living things get nutrients from their environment and turn it into energy through chemical processes.

• Bear's body turns the fish into energy
• Plants use sunglight for energy

Home

Maintains Homeostasis

All living things must regulate their internal environment to maintain a stable state through feedback interactions. THINK: What happens to your body when you get really hot or really cold?

Home

Every parent passes on genetic material to their offspring and every offspring resembles their parent(s) in some way. All living things have DNA, which contains genes/traits that organisms receive from their parents during reproduction.

Genetic Material/DNA

Home

Responds to Stimuli

All living things are able to sense physical or chemical changes in their environment and react to them.

Multicellular Organisms

Made up of more than one cell

Multicellular organisms are complex in structure and function and are made up of more than one cell. Some examples of multicellular organisms are: - animals - plants - fungi

Sexual Reproduction

Two Parents

In sexual reproduction, two parents contribute to the creation of offspring and combine genetic material together.

Asexual Reproduction

ONE Parent

In asexual reproduction, one parent duplicates their DNA and then divides equally to make an identical copy of itself.

Unicellular Organisms

One, Single Cell

Unicellular organisms are made up of only ONE cell. They are simpler in structure and function. They include organisms like:- bacteria - protists - ameoba - paramecium (there are some unicellular yeasts, algae, fungi
