Warm Up What is biology?
What is it? What is Biology?
Is the study of living thingsAll living things are called organisms
Characteristics of LifeLiving things are very organized and contain many complex chemical substances
Living things are made up of one or more cellsMulticellular- more than 1 cell Unicellular- 1 cell
Living things have a definite form and limited size
Living things have a limited life spanGastrotrich (a minute aquatic animal) 3 day life span Giant tortoise 177 year life span
Living things evolve or change over long periods of timeLiving things evolve or change over long periods of time. This is characteristic of groups of organisms, not of individuals.
Life Processes- determine living v. non-living1. Living things move.
2. Living things are able to reproduce.
3. Living things are sensitive and respond to changes in the environment.Does one rotten apple spoil the whole bunch? Ethylene
4. Living things need nutritionMake their food
5. Excrete waste. Examples: Sweat, urine, carbon dioxide
6. Living things respire (plants and animals use the oxygen in the air to turn food into energy)
7. Living things grow and develop.
Use the first letter from each process to help you remember them.Move Reproduce Sensitive Nutrition Excrete Respire Grow They spell MRS. NERG
This is MRS NERG ! Can you remember what each of the letters in her name stands for ?
Is it alive? Virus
1/9/12 Turn in any paperwork & Get out your M&M lab. Do-Now: In your warm up section on a blank sheet of paper, draw the picture illustrated on the side.
7A Cells Signs of life Building blocks of life Building living things
Where do minerals and water enter a plant? a. Through the bark b. Through the roots c. Through the stem d. Through the leaves.
Let’s look at living things
What it means to be alive. All living things have cellular organization. Think of cells as puzzle pieces that make up all living things This means.
CHAPTER 1 – THE NATURE OF LIFE THE NATURE OF LIFE.
Warm Up What are the 7 life processes?. Life Functions.
Looking at living things
The characteristics of living organisms. All living things are made of cells. have DNA obtain and use energy. Excrete wastes grow and develop. reproduce.
LIFE PROCESSES LIFE PROCESSESLooking at living things.
M : Movement R : Respiration (chemical process in cell which releases energy) S: Sensitivity (sensing the environment) G: Growth R: Reproduction E:
Circle map Living Things Examples of Living Things 6 Characteristics
AIM: WHAT CHARACTERISTICS DO ALL LIVING THINGS SHARE?
BIOLOGY What is biology? Biology is the study of life. What is an organism? Each individual living thing. Example: Bacteria, Paramecium, Cat, Rose etc.

An unmanned space probe was sent to Mars to check for signs of life on the planet. How could such a probe confirm the existence of life?
By Mrs. Kristin Shaw. At the end of this lesson you should be able to: ▪ Define Photosynthesis and Cellular Respiration ▪ Explain where each process happens.
