Topic: Cells Processes Aim: Describe the life processes that occur in living things. Do Now: Take out yesterday’s reading notes. Phase Changes ISA HW: Castle Learning Chemistry Part II – due Monday, November 16 th Chemistry Part II Exam on Monday 11/16 Atom Project Due Monday, November 23rd
2
Phases of Matter Review ISN 1.A ___________ takes the shape of a CLOSED container. 2.The particles that make up a ___________ VIBRATE. 3.A ___________ does not have a definite shape but DOES HAVE A DEFINITE VOLUME. 4.A ___________ consists of HIGH ENERGY particles. 5.The particles of a ___________ are TIGHTLY PACKED together. GAS SOLID LIQUID GAS SOLID
3
6. ATTRACTIONS between particles in a ___________ keep the particles from flying away. 7. The particles of a ___________ are NOT BONDED TOGETHER and MOVE FREELY through space. 8. The particles of a ___________ are COHESIVE. 9. A ___________ DOES NOT HAVE a definite shape or volume. 10. A ___________ can take the shape of an OPEN CONTAINER. LIQUID GAS LIQUID GAS LIQUID
4
Identify the phase change described. 1. Solid to liquid: 2. Gas to liquid: 3. Liquid to solid: 4. Solid to gas: 5. Liquid to gas: 5. Gas to solid: melting condensation freezing sublimation vaporization ABSORBED RELEASED ABSORBED deposition RELEASED
5
1. Identify what all organisms are made up of. They are all composed of CELLS.
6
2. Describe the difference between unicellular and multicellular organisms. Unicellular organisms consist of ONE cell. Multicellular organisms are composed of MANY cells.
7
3. Describe why energy is necessary for survival. Necessary for cells to carry out all life activities.
9
4. CONTRAST aerobic and anaerobic respiration. Aerobic respiration - utilizes oxygen to produce energy Anaerobic respiration - does not require oxygen to produce energy
10
C 6 H 12 O 6 6CO 2 + 2ATP Glucose Carbon dioxide Energy AEROBIC RESPIRATION ANAEROBIC RESPIRATION
11
5. Identify what is necessary for growth to occur. ENERGY
12
6. Describe the process of synthesis. Chemically COMBINE simple or smaller substances to form more complex substances. Small molecules LARGE MOLECULES
13
7. Identify an example of synthesis that occurs in organisms and identify the substance that is produced. Photosynthesis involves plants using light to synthesize glucose. Protein synthesis involves cells combining amino acids to produce large proteins.
14
Protein synthesis
15
8. Why is nutrition necessary for survival? Provides food for organism to produce energy. Provides nutrients needed for many cell processes.
16
Describe the difference between the 2 types of nutrition. Autotrophic nutrition – organisms produce their own food Heterotrophic nutrition – organisms cannot produce their own SO THEY HAVE TO INGEST FOOD
18
10. Identify the life process that involves the absorption and circulation of materials inside an organism. TRANSPORT
19
Locomotion
20
11. Contrast passive and active transport. Passive transport – does not require energy Active transport – requires energy
21
12. Identify the types of wastes that are excreted from the body. Cellular/Metabolic wastes
22
13. Identify 4 examples of metabolic wastes excreted from the body. Carbon dioixde Water Salts Nitrogenous wastes
23
14. Identify a change in the environment that organisms can detect. Stimuli
24
15. Describe the process of regulation. Controls and coordinates many life activities.
26
16. Describe homeostasis. Maintaining a STABLE INTERNAL ENVIORNMNET
27
17. Contrast asexual and sexual reproduction. Asexual reproduction - involves only one parent Sexual reproduction – involves 2 parents
28
18. Is reproduction necessary for survival? Support your answer. No. It is necessary for the survival of a species.
29
19. Describe what makes up an organism’s metabolism. All life processes within cells of an organism
30
20. Identify the factors that can affect your metabolism Gender Age Exercise Diet Drugs and alcohol
31
Review: Identify the life process described. 1.Used to produce energy. 2.Needed for a species to survive. 3.Type of nutrition in which organism produces its own food. 4.The movement of substances throughput a cell or organism. 5.Type of nutrition that requires an organism to ingest food. 6.The removal of metabolic wastes. 7.Type of respiration that does not use oxygen. Respiration Reproduction Autotrophic nutrition Transport Heterotrophic nutrition Excretion Anaerobic respiration
32
8. Sum total of all life processes. 9. When small substances join together to make larger substances 10. Control and coordination of all life processes. 11. Increase in cell size or cell number. 12. The ability to produce offspring. 13. Maintaining a stable internal environment. 14. Type of respiration that uses oxygen. Metabolism Synthesis Regulation Growth Reproduction Homeostasis Aerobic respiration
33
Let’s summarize… 1.Describe what your metabolism consists of. 2.Describe some factors that affect a person’s metabolism.
34
Which life function provides substances that may be used by an organism for its growth and for the repair of its tissue? (1.) nutrition (2.) excretion (3.) regulation (4.) reproduction
35
In an organism, the coordination of the activities that maintain homeostasis in a constantly changing environment is a process known as (1.) regulation (2.) digestion (3.) synthesis (4.) respiration
36
The life process of transport in an organism directly involves those activities used to (1.) release energy from food (2.) produce cellular waste products (3.) obtain and hydrolyze materials (4.) absorb and distribute materials
37
The final result of the process of respiration in animals is the (1.) Release of oxygen as a waste product (2.) Use of carbon dioxide to form sugars (3.) Transfer of chemical energy to a more usable form (4.)Enzymatic decomposition of inorganic raw materials
38
Which life function is most directly involved in the control of the muscles of an earthworm that is moving from dry soil to moist soil? (1.) Regulation (2.)Transport (3.) Nutrition (4.) Excretion
39
The movement of an organism from one place to another is known as (1.) Circulation (2.) Transport (3.) Locomotion (4.) Synthesis
