Review previous day Biotic/Abiotic What makes something alive (biotic) or not alive (abiotic)? What is Spontaneous Generation?

Slide 6

Organisms An ORGANISM is a living thing All organisms share characteristics that separate them from non-living things All organisms share EIGHT characteristics that make them alive. A living (biotic) organism must have all EIGHT !

Slide 7

All living things are made up of cells. A cell is the smallest unit of life CELL: the smallest basic unit of structure and organization of all living organisms Some organisms have only a single cell others have many the human body contains over 100 trillion cells Thats 100,000,000,000,000!!

Slide 8

All living things display organization. Arranged in an orderly way Cells Tissues Organs Organ Systems Organism

Slide 9

All living things grow and develop Growth: addition of mass to an organism Development:the process that occurs in an organism's life that results in a more complex organism.

Slide 10

Basically, this means that they can make more of their own kind! SPECIES: A group of organisms that mate together and have fertile offspring Asexual Reproduction when a single parent doubles its contents and splits in two to create a new organism (ex:bacteria) Sexual Reproduction when two different parents unite to produce a new organism (ex:humans) MITOSIS All living things reproduce.

Slide 11

All living things respond to stimuli. Stimuli: Anything from the environment that causes some sort of reaction, such as temperature, light, sound, and other factors that cause living things to respond. Nonliving objects (rocks for instance) do not respond to stimuli!

Slide 12

All living things require and use energy. Used to run the processes of life Humans (and other animals) get energy from the food we eat Plants get energy from the sunlight, through a process called photosynthesis

Slide 13

All living things can move Animals move to find food and shelter. Movement can be the difference between life and death. Plants do not move, but they bend toward sunlight. All living things also have internal movement of substances (food, water, waste, etc.)

Slide 14

1-13 Adaptations come about through evolution. Evolution is the process by which a species changes through time. Living things adapt

Slide 15

All living things are homeostatic Homeostasis is the ability of an organism to maintain relatively constant internal conditions. An example is temperature regulation in the human body. All organ systems contribute to homeostasis.

Slide 16

Quick Group Discussion!!! What about dead things?
