Characteristics of Life
Cells & Energy
Classifying Living Things
Tiny but Mighty (Viruses, Bacteria, Protists, Fungi)
Plants, Animals & Adaptations
100

All living things are made of one or more of these.

What are cells?

100

The smallest unit of life.

What is a cell?

100

The science of naming and grouping organisms.

What is taxonomy?

100

These are not considered living by many scientists because they are not made of cells.

What are viruses?

100

Most plants make food through this process using sunlight.

What is photosynthesis?

200

The process of keeping internal conditions stable, like your body keeping the same temperature.

What is homeostasis?

200

An organism made of only one cell.

What is unicellular?

200

The most specific classification group.

What is species?

200

Viruses need one of these in order to reproduce.

What is a host cell?

200

Animals are classified this way because they have many cells and eat other organisms.

What are multicellular heterotrophs?

300

A change in the environment that causes an organism to respond.

What is a stimulus?

300

An organism made of many cells.

What is multicellular?

300

The two words that make up an organism’s scientific name.

What are genus and species?

300

Unlike viruses, bacteria are considered alive because they have this.

What are cells?

300

A trait or behavior that helps an organism survive in its environment.

What is an adaptation?

400

A sunflower turning toward sunlight is an example of this characteristic of life.

What is responding to a stimulus/environment?

400

Plants are called this because they make their own food.

What are autotrophs?

400

Scientists classify organisms so they can do this.

What is organize, identify, and communicate about living things?

400

Bacteria and fungi are helpful because they break down dead organisms and recycle nutrients.

What are decomposers?

400

A cactus storing water in its stem is an example of this.

What is an adaptation?

500

Name four characteristics that scientists use to determine if something is living.

  • made of cells
  • uses energy
  • grows/develops
  • reproduces
  • responds to surroundings
  • maintains homeostasis?
500

Humans, animals, and fungi are examples because they get energy by consuming other organisms.

What are heterotrophs?

500

Put these levels in order from largest to smallest:
species, kingdom, domain, genus

What is:
Domain → Kingdom → Genus → Species?

500

A mushroom belongs to this kingdom.

What is fungi?

500

A scientist discovers an organism that has many cells, moves to find food, and cannot make its own energy. It most likely belongs to this kingdom.

What is the Animal Kingdom?
