Properties of Life

Biology – What’s in a name?? What does BIOLOGY mean? “Bio-” means “life” “-ology” means “the study of” All living things share characteristics but are also influenced by there surroundings. Factors that affect living things… BIOTIC factor– references aspects that affect life that are considered “living” includes something that is DEAD – because it was once living ABIOTIC factor– references aspects that are NON- living (but can be just as important) “A-” is a prefix for “opposite of” or “against”

What things are considered living? Animals FungiPlants ProtistsBacteria Stone?

There are 7 themes that biological entities share. They are known are the 7 Properties Of Life. These are the things all living things share in common. They unite all life.

What does it mean to be alive? Move? Reproduce? Breath? Eat? Heart Beat? Drink Water? Cells?

There are 7 Properties All Living Things Have in Common 1. Cellular Organization 2. Metabolism 3. Homeostasis 4. Growth & Development 5. Reproduction/Heredity 6. Responsiveness/Interaction 7. Evolution

1. Cellular Organization All living things are made of one or more cell. Highly organized structure And there is a hierarchy of cell organization in living things. (right) Organism Organ System Organ Tissue Cell: Where life begins Organelle Multicellular Organisms Single Cell Organisms

2. Metabolism = Use energy = Sum of all chemical reactions in the body. Anabolic = build Catabolic = break down All living things obtain and use energy (Eating, Breathing, Drinking Water) All energy originates with the sun. Plants transfer sunlight into chemical energy. Your cells need energy to grow, develop, repair damage, reproduce. And we get that energy from eating.

3. Homeostasis = Maintaining stable internal condition when the outside can change. Humans operate most efficiently at 98.6°. Changes just a few degree can be life threatening. Stability is incredibly important to our chemistry!

4. Growth & Development = All organisms have a life cycle, grow, and change Some life is way more dramatic than others. Bacteria = 20minutes. Oldest tree is over 5000 years old!

5. Reproduction/ Heredity All organisms reproduce in order to continue the species’ existence. Heredity = Traits are passed on from parents to offspring through genes.  Asexual: If there is one parent then the offspring look just like the parent (clones)  Sexual: If there are two parents then the offspring are a mosaic of traits from contributing DNA.

6. Response! Respond and Adjust to Environment All organisms respond to changes in their environments. Example Light Gravity Heat Fight or flight Phototropism Auxin, a growth regulator in plants, controls directional cell elongation that takes place in phototropism

7. Evolution Populations of organisms change over time leading to the great diversity in life we see. Evolution is bound to the more favorable traits. 4 Tenets of Evolution 1.Variation 2.Traits are passed on 3.Overproduction 4.Many offspring don’t survive because of competition.

Double Check Let’s reconsider the question about the tree. Which properties did you include? Which properties do you need to change? Which properties do we need to remove? Honors

Concept Check Is it Living?... Why?

Shoulder Partner… Talk it over and come up with any 3 biotic factors and 3 abiotic factors. 1 minute… GO! Quick share…  What are the biotic & abiotic factors in this scene?

Practice Identifying the Properties in Samples… In your groups, analyze the picture and decide if it’s living or not. Give three reasons for each. These will become a handout that you will make a part of your notes. The “Analysis Questions” & “are CW/HW and are due tomorrow. Biotic/Abiotic: Only question #1 (don’t’ do #2). List at least 3 for each. “Analysis Questions are for the living v non-living practice. Living v Non-living: Determine if it’s living or not and give 3 reasons as justification.

Continuing… - How did you do? 1. Polar Bear = Living 2. Rock = Not Living 3. Sunflower = Living 4. School of Fish = Living 5. Dirt = Not Living 6. Euglena = Living 7. Seeds = ? Complete the “Analysis” for credit. BIO LIVING! Just barely…

Today… You will choose an organism. If you have been reading the warm- ups you should have brought in a picture from home. You will use this picture as the focus for examining the properties of life further.

Try these… ___ tree ___ rock ___ fire ___ boy ___ wind ___ rabbit ___ cloud ___ feather ___ grass ___ seed ___ egg ___ bacteria ___ cell ___ molecule ___ Sun ___ mushroom ___ potato ___ leaf ___ butterfly ___ pupae ___ fossil ___ hibernating bear ___ mitochondria ___ river

Properties of Life Graphic Organizer

Is it living? “Living” is an important term that has very specific definitions. Unfortunately, it can sometimes be difficult identify all of them in living things. You know most of these properties already. Recall yesterday’s question about the tree. What were you ideas? How about the apple? It’s important to know that something is living by scientific definition if it exhibits all 7 properties.

1.Cellular Organization All living things are made of one or more cells. 2.Metabolism Living things break things down then build things back up. This is evident in obtaining energy to live (eating other organisms) 3.Homeostasis Maintaining stable internal conditions when things outside change. For example, we shiver when it’s cold and we sweat when it’s hot but our internal temperature stays pretty stable. 4.Growth & Development Living things grow in size or number in cells and have a life cycle, they live and then eventually die. 5.Reproduction/Heredity Living things make babies (officially called offspring). Those babies have traits given from their parents. Meaning they have genes (eye color for example) that were given to them by their parents. 6.Responsiveness/Interaction Living things respond to outside influences. Flowers open in sunlight and gazelle run when chased. 7.Evolution As generations increase, random mutation and genetic combinations contribute to variability. These 7 terms define what is living. All life is united by these 7 properties. 7 Properties of Life

Properties of Life Classwork Choose your organism, any organism. – This should be the organism you brought in. – You can draw one or make it up if you didn’t. Draw or paste a picture of this organism in the middle of the page. – See next slide. In bubbles around the outside, label, define, and describe the 7 properties of life and how this organism displays using them. Once graded, these could be put up on the side wall.

Due: _______ Use color & Be neat & creative. Do this on a piece of copy/construction paper provided. Property of Life: Explanation Ex: Metabolism: the sum of chemical reactions in the body that help build up & break down the organism.
