Lesson 6.01Organization of Life
Key Points -The world is organized in a special
way. -Living things are also organized according
to a hierarchy (order from smallest to
largest). Organization of Life Atoms gt
Molecules gt Cells gt Tissues gt Organs gt Organ
Systems gt Organisms Question What is the
smallest level of organization?

Lesson 6.02Cell Theory

• Key Points
• -The cell theory was developed to show the
  relationship between cells and living things.
• There are three parts to the cell theory
• All living organisms are made of cells.
• All cells come from other cells.
• Cells are the basic unit of life

• -All living things are made of cells unicellular
  or multicellular
• -All cells come from other cells All living
  things reproduce organisms that are the same.
  Cells divide by mitosis
• Cells are the basic unit of life All have the
  six properties of life homeostasis,
  organization, metabolism, growth, adaptation,
  response to stimuli, and reproduction.
• Question How many parts make up the Cell
  Theory?

Lesson 6.03Organelles

• Key Points
• -The different parts of the cell are called
  organelles Cell Membrane, Cell Wall,
  Chloroplast, Cytoplasm, Endoplasmic Reticulum,
  Golgi Apparatus, Mitochondria, Nucleus, and
  Vacuoles
• -Animal cells differ from plant cells.
• Plant cells contain some extra organelles that
  animals do not have Cell Wall and Chloroplast.
• Question
• Why dont animals cells need a
• Cell Wall or a Chloroplast?

Animal Cell

Lesson 6.04Cell Processes
Maintain balance!

• Key Points
• -Cells maintain a balance called homeostasis.
• -The cell membrane is the gatekeeper of the
  cell controls what comes in and out of the cell.
• -Cells extract energy from food for reproduction/
  growth/homeostasis Mighty Mitochondria is the
  organelle that is responsible for this
• -QUESTIONS
• How does the cell membrane help to maintain
  homeostasis for the cell?
• Cells use energy for
• What is homeostasis?
• What organelle within cells extracts energy from
  food?
• Why is it important to maintain homeostasis?

Lesson 6.05Human Body Systems
Key Points -There are several major system of
the body The Nervous System, The Circulatory
System, The Respiratory System, The Immune
System, The Digestive System, The Musculoskeletal
System, and The Reproductive System. -The body
systems MUST work together to properly
function. Question Which Human Body System
breaks down food into energy?
7
Lesson 6.06Infectious Agents
Key Points -There are many types of infectious
agents that may infect humans. Bacteria are
single-celled living organisms because they
exhibit the 6 properties of life (Homeostasis,
Organization ,Metabolism , Growth, Adaptation,
Response to Stimuli, and Reproduction) Viruses
are nonliving infectious agents. Viruses cannot
reproduce or produce energy on their own. They
must live inside a host cell. Viruses enter cells
inside our bodies and use the cells to reproduce
and produce energy. Fungi are organisms that
can cause infection. Some types of fungi are
multicellular and some are unicellular. Some
examples of fungi include molds, mildews, yeast,
and mushrooms. Parasites are organisms that
feed on other organisms for food. Some common
examples of parasites are mosquitoes, ticks, and
tapeworms. Question Which Infectious Agent
listed above is not alive?

Lesson 6.07Classification

• Key Points
• We put everything around us into groups from
  general to specific!
• Domain Archaebacteria (bacteria that can live in
  extreme environments), Eubacteria (bacteria that
  live in and among us), and Eukaryote (plants,
  animals, fungus, and other simple organisms)
• Kingdom
• Phylum
• Class
• Order
• Family
• Genus
• Species
• Easy way to remember the order
• King Philip Came Over for Great Spaghetti!
• Question Which Classification Group above is
  the
• most specific?
