1. Defining Life Characteristics of Life Lesson 1: Characteristics of LifeMiKeKiM Educational Services: Biology1

2. Characteristics of Life: Acquire Energy Lesson 1: Characteristics of LifeMiKeKiM Educational Services: Biology2 Energy “E” -Defined:the capacity to do work 1 -Is obtained from the nutrients consumed 2 -Metabolism are the chemical reactions that “E” is used in 3 Homeostasis -Defined:the maintenance of internal environments 3 -It takes “E” to do this -Homeo = Like stasis = Standing -Requires monitoring and correcting 4 -Example: House Temperature 5

3. Characteristics of Life: Respond Lesson 1: Characteristics of LifeMiKeKiM Educational Services: Biology3 Responding -Defined:Ability to sense and take action 1 -A response is in reaction to some stimulus 2 -Example: What do you do if you put your hand into a flame? You detect the stimulus of heat and respond by pulling your hand away.…and maybe a murmur of. ouch

4. Activity 1: Laboratory Based Lesson 1: Characteristics of LifeMiKeKiM Educational Services: Biology4 Viewing Protists Amoeba Feeding 1. Notice that it exhibits responding to the environment by moving towards it prey. 2. Notice that it will break down its prey to acquire “E”. Rotifer Feeding 1. Notice that it exhibits responding to the environment by leans towards it prey then opened it mouth AND when threatened it pulled back. 2. Notice that it will break down its prey to acquire “E”.

5. Life Characteristics: Lesson 1MiKeKiM Educational Services: Biology5 Activity 2 Explain what the stimulus is in the examples. Click your mouse to get the answer: 1. A plant moves turns towards the sun to get the light energy 2. A plants root grows towards a water source. 4. You smell food and you respond by salivating. Back to the lesson Light is the stimulus Water is the stimulus Odor is the stimulus

6. Characteristics of Life: Reproduce Lesson 1: Characteristics of LifeMiKeKiM Educational Services: Biology6 Reproduction -Defined:The process to create new generations -Types Sexual: Requires two parents 1 Asexual: Requires one parent 2

7. Activity 3: Laboratory Based Lesson 1: Characteristics of LifeMiKeKiM Educational Services: Biology7 Viewing Protists Paramecium Dividing Euglena Dividing Hydra Dividing Yeast Dividing Which one(s) use Asexual Reproduction and by what process? Paramecium via Binary Fission Euglena via Binary Fission Hydra via Budding Yeast via Budding Which one(s) use Sexual Reproduction? Bacteria via Conjugation Bacteria Dividing
