1 Date: April 24th, 2017 Aim # 40: What processes must all living things be able to carry out? HW: Homework packet due tomorrow Quiz Thursday on Characteristics of Life and Life Functions Do Now: List some of the characteristics of living things that we discussed last week.

2 Biology is the study of life
What is Biology? Biology is the study of life

3 SO… WHAT IS LIFE Life is defined by a list of characteristics organisms must possess to be considered living. All living organisms contain the same life functions although their means of achieving them may be different

4 Life Functions Two Types of Nutrition Autotrophic Heterotrophic
1. Nutrition - activities of an organism, used to obtain materials from the environment and process them for their use. Two Types of Nutrition Autotrophic Heterotrophic Materials CO2 H2O Light Energy Organic Food Process Photosynthesis Ingestion Digestion Egestion Organism Plants & Algae All other organisms

5 Nutrition Autotrophic Heterotrophic

6 Life Functions 2. Transport - involves the absorption and distribution of materials within an organism.

7 Life Functions Respiration - includes the chemical process by which an organism obtains energy (ATP) from its food (Glucose). Food (glucose)

8 Respiration vs. Breathing
Breathing is taking air in and out Respiration is converting food into energy.

9 Life Functions 4. Excretion - the removal of wastes produced by cells during metabolic activities. kjkjdlkfjlkjflkdslfjklsadjfklsjadkfjlsd

10 Life Functions Synthesis - includes the chemical activities by which an organism builds larger molecules from smaller ones. (to make) kjkjdlkfjlkjflkdslfjklsadjfklsjadkfjlsd

11 Life Functions 6. Regulation - involves the control and coordination of various activities in an organism. (Nervous system and Endocrine system play a role). kjkjdlkfjlkjflkdslfjklsadjfklsjadkfjlsd

12 Life Functions 7. Growth - increases in cell size and/or cell numbers.

13 Life Functions 8. Reproduction - production of new individuals. A species’ survival depends on reproduction. An individual’s survival does not.

14 II. Important Terms 1. Metabolism - refers to all the life functions needed to sustain life. Does not include reproduction 2. Homeostasis - the maintenance of a stable internal environment. (Regulation helps to achieve Homeostasis) Your body systems are constantly adjusting to maintain homeostasis.
