Characteristics of ALL LIVING THINGS

1) All living things

Respire• Living cells release ___________ from _____________ molecules.

• The form of _______________ that releases the most energy use __________.

• Many multicellular organisms have _____ _____________ systems to supply thir cells with oxygen from their environment

2) ALL LIVING THINGSRespond to their

environment

A signal to which an organism responds= ___________________

2) ALL LIVING THINGSRespond 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.

2) ALL LIVING THINGSRespond to their

environment A stimulus can be____________

VOCAB WORD

A cell works to keep conditions inside the cell constant = ______________________

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

. . . the cell will die.

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.

HOMEOSTASIS
