AIM: WHAT CHARACTERISTICS DO ALL LIVING THINGS SHARE? Do Now: On your paper. Today’s notes will be in purple. Looking at living things… All living things… All living things must do certain things in order to maintain homeostasis (a stable internal environment) All the life processes and chemical reactions living things do are called metabolism. Living things Although all living things look different from each other, they all have eight things in common. These eight things are called life processes. Something is only alive if it does all eight processes. THE EIGHT LIFE PROCESSES 1 All living things have Movement (Transportation) Animals move their whole bodies Complex organisms have a circulatory system to carry and exchange materials. Transport can also be defined as the intake and distribution of material throughout an organism. Example: Plants transport water and food up their stems and down to the roots. 2 All living things undergo Respiration (Anaerobic and Aerobic) All living things exchange gases with their environment. Plants and animals use the oxygen in the air to turn food into energy. Plants use carbon dioxide to make sugars using the process of photosynthesis. 3 All living things are Sensitive All living things respond to changes. Living things notice changes in their surroundings and react to them. They do this to maintain Homeostasis. Ie. Plants grow towards the light. Ie. Animals are sensitive to many things such as noise, light and temperature change. 4 All living things Grow (Development) Babies grow into adults. Seedlings grow into plants. Living things become larger and more complicated as they grow. 5 All living things have Organization Organisms are arranged into cells, then tissues, organs and finally organ systems. Even cells are organized by little specialized individual compartments called organelles. 6 All living things need Nutrition (Heterotrophic and Autotrophic) Food is used to provide energy. Green plants make their own food using sunlight. Animals eat plants or other animals. 7 All living things Excrete (aka. Excretion) Waste substances must be removed from the all living things. Plants and animals both need to get rid of waste gas and water. If wastes remained in the body it would be poisonous. 8 All living things Reproduce Humans have babies, cats produce kittens, pigeons lay eggs. New plants grow from seeds. Without reproduction, a species would go extinct (die out). The eight life processes 1. Movement 2. Respiration 3. Sensitivity 4. Growth 5. Organization 6. Nutrition 7. Excretion 8. Reproduction Use the first letter from each process to help you remember them. Movement Respiration Sensitivity Growth Organization Nutrition Excretion Reproduction The eight life processes spell MRS. GONER This is MRS GONER ! Can you remember what each of the letters in her name stand for ? MRS. GONER stands for… M? R? S? G? O? N? E? R? Movement Respiration Sensitivity Growth Organization Nutrition Excretion Reproduction Wrap-Up! Turn to the chapter 1 word wall on page 9. Record at least two “new to you” words that we used in class today.
