Living and Non-Living 8/22/17

Characteristics of All Living Things Have cells. Sense and respond to change. Reproduce Use energy Grow and develop Excrete waste Maintain homeostasis

1) Living things have cells We are made up of trillions of cells Some organisms are made up of just one cell

2) Living things sense and respond to change All organisms have the ability to sense change in their environment. Example: Our Pupils Get smaller when exposed to light Get bigger in the dark

2) Living things sense and respond to change The outside environment of an organism may change, but conditions inside an organism must remain the same Example: Our bodies stay at 98.6o F If we get hot, our bodies sweat to cool us down. If we get cold, our bodies twitch (shivering) to warm us up.

3) Living things reproduce Organisms make other organisms that are similar to themselves. Organisms reproduce one of two ways: Sexual Reproduction : 2 parents produce offspring that have characteristics of both parents Asexual Reproduction : a single parent produces offspring that is identical to the parent.

4) Living things use energy - Organisms use energy for everyday activities: Breaking down foods Building new cells Homeostasis

5) Living things grow and develop All living things grow during periods of their lives. →

6) Excrete Waste Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. 

Homeostasis ***Process of Keeping an organism’s internal environment stable….even though the external environment is constantly changing!! ***This takes a lot of energy!
