Topic: Cells Processes
Aim: Describe what makes up an organism's metabolism and the various factors that influence metabolism.
Do Now: 1. Pass up yesterday’s Microscope Lab.
2. Take out Microscope picture
3. Review some Castle Learning Measurement Questions
HW: • Metric Conversions corrections if you scored an 8 or less• Castle Learning due Monday• Procedures due Friday
Arlo measured a block of wood, as shown in the diagram.
What is the length of the wooden block in millimeters? (1 cm = 10 mm)
1) 2.60 mm 2) 26.0 mm3) 260 mm 4) 2,600 mm
1. The amount of space an object takes up is
(1) mass (2) volume (3) density (4) grams
2. The metric unit for volume is a
(1)gram (2) liter (3) meter (4) cubic foot
3. The amount of matter an object has is called
(1)mass (2) volume (3) milliliters (4) density
4. The SI unit of mass is the ______. (1)cubic meter (2) kilogram
(3) liter (4) meter
5. In the metric system, the height of a building would be given in
(1)centimeters (2) milliliters (3) meters (4) millimeters
6. Which instrument would be used to obtain the volume of a glass of water?
(1) triple beam balance (2) graduated cylinder (3) beaker (4) metric ruler

Metabolism•Sum TOTAL of all life processes in the body
•Every living thing carries out metabolic activities
Respiration•Process that
releases ENERGY from food
Transport•Circulation•Movement of
materials within an organism
Nutrition •When organisms take in and use materials needed for energy and all life processes
2 types of nutrition
1.Autotrophic: produce own food
•Plants, Algae (Photosynthesis)
2. Heterotrophic:•Organisms must ingest food already made in the environment
•Animals, fungi, some unicellular organisms
Regulation
•CONTROL and coordination of life activities
•Maintains homeostasis (STABILITY)
•Involves the nervous and endocrine system
Excretion •Removal of cellular (metabolic) waste
Locomotion•Ability of an organism to move
Factors that influence metabolism
•Gender•Age
• Exercise• Diet• Drugs and alcohol
Let’s summarize…
1. Describe what your metabolism consists of.
2. Describe some factors that affect a person’s metabolism.
Review:
Which term includes all the activities required to keep an organism alive?
(1.) metabolism
(2.) growth
(3.) nutrition
(4.) excretion
An activity carried on by all living plants and animals is
(1.) reproduction
(2.) respiration
(3.) photosynthesis
(4.) transpiration
Which life process prevents the accumulation of metabolic wastes in a bald eagle?
(1.) nutrition
(2.) excretion
(3.) digestion
(4.) ingestion
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
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
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
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
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
The movement of an organism from one place to another is known as
(1.) Circulation
(2.) Transport
(3.) Locomotion
(4.) Synthesis
Review: Identify the life process described.1. Used to produce energy.2. Needed for a species to survive3. The breakdown of food4. Type of nutrition that requires an
organism to ingest food5. The ability to move6. The removal of metabolic wastes7. When organisms take in materials from
the environment to use
8. Type of nutrition in which an organism produces its own food
9. The movement of substances throughout an organism or cell
10. When small substances join together to make larger substances
11. The removal of undigested food12. Taking in food13. Increase in cell size or cell number.
