Characteristics of Life

All living things must. . . ● Respond to their environment. ● Grow and get stronger. ● Be able to have babies ● Keep a stable body temperature ● Use energy ● Made of cells

Response to the environment ● All Living things detect changes and respond to them ● Animals use their eyes, ears, and nose. ● Some animals have senses that we don't have, like the ability to sense tiny vibrations from smaller animals that they eat.

Growth and Development ● All living things grow and develop! ● By eating the correct foods, us humans grow and develop too. ● When you plant a seed, it grows and gets stronger when you water it and give it sunlight. This is an example of Growth and development.

Making offspring ● All animals are capable of reproduction ● There are two types of reproduction: ○ Sexual (with a partner) ○ Asexual (capable of reproducing without the need of a partner) ● It is as simple as a single cell dividing to form two cells.

Keeping a stable body temperature ● All living things are able to maintain their body temperature ● No matter if it is snowing, raining, storming, or really hot outside, an organism can keep their body temperature the same. ● Keeping a stable body temperature is called Homeostasis ● Ex. Shivering

Use of Energy ● All living things obtain energy ● Different animals get energy different ways ● All living things also have a complex chemistry ● Thousands of chemical reactions happen in every cell all the time

Made of cells A cell is the most basic structure of living organisms All lives have at least one cell Wide array of differences and similarities of living things
