2. Ch 10.1 Vocabulary
Element- a pure substance that cannot be broken down into other substances by chemical or physical means.
Atom- the basic particle from which all elements are made; the smallest particle of an element that has the properties of that element.
Compound- a substance made of two or more elements chemically combined in a specific ratio (part), or proportion (amount)
Unicellular- Made of a single cell.
Multicellular- Made of many cells.
Tissue- A group of similar cells that perfom a specific function.
Organ- A body structure that is composed of different kinds of tissues that work together.
Organ system- A group of organs that work together, performing major functions

4. What are the Levels of Organization in an Organism? Pg. 363
Organisms, or living things, are made of tiny particles that can join together, making larger structures.
The levels of organization in an organism are:
Smallest atoms
elements
molecules
compounds
cells
Tissues
Organs
Largest organ systems

5. The levels of organization in an organism from smallest to largest:
Elements
compounds

6. Elements make up matter.
Elements and Atoms pg. 363
Every living and nonliving thing is a type of matter.
Elements make up matter.
An element is any substance that cannot be broken down into simpler substances.
Important elements in the body include: carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, calcium, and sodium.
The smallest unit of an element is a particle called an atom.
Any single element is made up of only one kind of atom.

7. Levels of Organization pg. 363
Elements
The colored spheres represent atoms.
Which examples represent the same element?

8. Elements and Atoms pg. 363
Living things and non living things are made of ____________.
Matter is anything that has _______ and takes up __________.
Elements make up __________.
_________ substance that cannot be broken into simpler substances.
Examples of elements found in your body:__________, ____________, _______________.
The smallest unit of an element is an ____________.

9. Compounds and Molecules pg. 364 C02
Compounds form when two or more elements combine__________. The smallest unit, of many compound is a ____________.
The molecules that all living things need are:
Carbohydrates, lipids, protein, water, and nucleic acids.
N______ _______ contain the instructions necessary to carry out all the functions of life.
DNA= important nucleic acid
This genetic material carries information about an organism and is passed from parent to offspring

10. Compound- a substance made of two or more elements chemically combined in a specific ratio (part), or proportion (amount)
Carbohydrates, lipids, proteins, water, and nucleic acids are molecules that all living things need. Nucleic acids contain the instructions necessary to carry out all the functions of life.
One important nucleic acid is DNA, the genetic material that carries information about an organism and is passed from parent to offspring.

11. Levels of Organization pg. 364 Molecules and Compounds
Carbon dioxide is a compound. So is water.

12. Cells may be specialized cells. (SC)
Cells pg.365
A _______ is the basic unit of structure and function in living things.
If a living thing has only 1 cell, it is called
unicellular
Examples of multicellular (which means “made of many cells.”)
Plants and animals
Multicellular= all cells MUST carry out key functions to survive
Cells may be specialized cells. (SC)
SC perform specific functions that benefit the entire organism. Specialized cells may differ in structure as well as in function.

14. Tissues, Organs, and Organ Systems pg. 366
In multicellular organisms= cells are organized into tissues, organs, and organ systems. A _tissue_ is a group of similar cells that work together and perform a specific function. An organ is made of different kinds of tissues that function together. A group of organs that work together and perform one or more major functions is an organ system Organ systems work together in an organism. The level of organization becomes more complex from cell to tissue to organ to organ system. Examples of organ systems:_________________ & ________________
