What Does It Mean to Be Alive? Characteristics of Life REMEMBER: You need to fill in your notes with words that are in green.

All living organisms share some basic properties Intro to Characteristics of Life

Made of Cells Smallest living thing Unicellular vs Multicellular

Organisms can be: Unicellular – one cell Entire organism is made up of one single cell Bacteria and protists Multicellular- more than one cell The entire organism is made up of many cells Cells have specialized functions within the organism

Reproduction All living things Reproduce – produce offspring of their own kind Necessary for the survival of the species

Two types of reproduction Asexual Reproduction A single parent organism reproducing by itself Sexual Reproduction Two different parent organisms (male and female) contribute DNA to produce a new organism. Bacterial Reproduction - E.coli

Based on a Universal Genetic Code All organisms share the same basic genetic code, but every organism has a different arrangement of the genetic code Genes carry hereditary information Genes are composed of DNA DNA determines our inherited traits DNA is a BIOMOLECULE  Nucleic Acid Nucleotides (Monomer)  DNA (Polymer)

DNA code is passed from generation to generation. The passing of inherited traits is the reason children look like their parents.

Grow and Develop All organisms Grow and Develop Growth Physical change in size, over a period of time or an increase in the number of cells.

Development Change in the physical form or physiological make- up of an organism Physiology Study of functions in living systems. How your body works.

Need and Use Energy Living organisms need energy to grow, develop, repair damage, and reproduce

Metabolism The combination of all chemical reactions in an organism in which an organism build up or breaks down molecules Breaking down big molecules into smaller molecules + Building up big molecules = Metabolism

Respond to Their Environment Organisms react to immediate changes or needs (stimulus) Stimulus: Something that causes a physiological response Response: Reaction to stimulus

Examples of Stimuli (plural for stimulus) Light Temperature Sound Gravity Heat Water Pressure Plant response to light

Maintain a Stable Environment Homeostasis (Internal Balance) External condition may change dramatically, but all organism must keep internal conditions relatively stable by the process of Internal feedback

Some examples of stable conditions in our body that are necessary for life Body temperature Blood volume pH balance Water balance

Change Over Time Over multiple generations, organisms must change by adaptation to their environment and through the process of natural selection

Natural Selection Gradual process by which biological traits become more or less common in a population through reproduction and environmental influence.

Adaptation A process that enables organisms to become better suited to their environment
