It’s Alive!

Characteristics of Life?

• Look around the room. There are many living and non-living things, such as lights and books. There are many living things such as people.

Maintain a stable internal environment

Reproduce

Obtain and use materials & energy

Respond to their environment

LIVING THINGS ARE:

CELL

...Are Composed of Cells•  Cells are the basic components of all living

things. Some organisms are single celled, like bacteria, or multi-celled, like humans.

This is a single-celled organism called an amoeba.

ALL LIVING THINGS5. Respond to their

environment

A stimulus can be_________________

Ex: When there is enough water and ground is warm enough, seed germinates. Roots respond to gravity & grow downward.Leaves respond to sunlight & grow up.

environment

A stimulus can be____________

Ex: When the glucose level in your bloodstream becomes low, your body responds by making you feel hungry.

ALL LIVING THINGS6. Homeostasis

Keep conditions inside the cell constant = ______________________

IF temperature, water content, nutrients, acidity change too much

. . . the cell will die.

HOMEOSTASIS

6. HOMEOSTASIS involvesinternal __________ mechanisms

If body temp drops too low,“shivering” produces heat to warm you up.

If temp is too hot, “sweating” cools you down.
