Life Processes

Mr. MahLiving Environment

Lecture 1

In your notebooks, answer the following questions:

What does the word “life” mean to you?

What makes something living?

Warm-up

There is no textbook for this class. All of the exams are going to be based on what I cover in lecture.

Make sure you take EXTREMELY GOOD NOTES during the entire class.

We’ll be using Victory Notes for note taking

Victory Notes

These are the most basic events, or processes, that need to happen in order for an organism to be alive.

Even the most basic living things, like bacteria performs all of the Life Processes.

What exactly are Life Processes?

AIM: What makes something living?

What does it mean to be living, or non-living?

Living Non-living

VirusBacteria

Digestion Circulation Movement Excretion Respiration Reproduction Immunity Coordination Synthesis

Life Processes

Breakdown of food to simpler molecules which can enter the cells

What does it mean? Everything needs to eat!

We all need food to survive, no matter what kind of living organism we might be.

Digestion

the movement of materialswithin an organism or itscells

Food has to get aroundto all of the cells in our body.

Ex: Our heart pumps blood throughout our body. Food is carried by the blood

Circulation

(locomotion) change in position by a living thing

Even plants move! Let’s think about this one. Plants grow from tiny seeds, but we think about plants as not moving.

Plants grow upward, down into the soil, and outwards. Think of trees. They might not be moving, but their branches change position.

Movement

removal of waste products by an organism (wastes may include carbon dioxide, water, and urea in urine and sweat)

All the waste that an organism creates needs to go somewhere. Different organisms have unique ways of getting rid of that waste

Excretion

process which converts the energy in food to ATP (the form of energy which can be used by the cells)

IMPORTANT: its not respiration like breathing. They are two very differentthings.

This definition of respirationhappens in cells, where they break down food to make energy called ATP (Adenosine Triphosphate)

Respiration

It’s a hard topic, and we’ll definitely study it more in depth later on the in the year. For now, you just need to recognize that it is one of the Life Processes.

Respiration

the making of more organisms of one's own kind -- not needed by an individual living thing but is needed by its species

Reproduction

Types of Reproduction

Asexual Sexual

the ability of an organism to resist disease causing organisms and foreign invaders

This is how we get better whenever we get sick

Video Clip

Immunity

the control of the various activities of an organism (mostly involves the nervous system)

Organisms have control over their movements and actions

This is a Lack of Coordination… (Video Clip)

Coordination

the production of more complex substances by combining two or more simpler substances

Ex: Plants use water and carbon dioxide to make sugar (much more complicated)

Synthesis

Digestion Circulation Movement Excretion Respiration Reproduction Immunity Coordination Synthesis

Life Processes

Non-living things are incapable of carrying out at least one or more of the life processes.

Living vs. Non-Living Organisms

Classify the following as Living or Non-Living

On a sheet of loose-leaf lined paper, write the following:For each living organism, write down how they show all of the Living Processes

For each non-living organism, write down theLiving Processes that they are missing
