lesson 6 01 organization of life
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 > Molecules > Cells > Tissues > Organs > Organ Systems > Organisms

Question: What is the smallest level of organization?

lesson 6 02 cell theory
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 03 organelles
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 don’t animals cells need a
  • Cell Wall or a Chloroplast?

Animal Cell

lesson 6 04 cell processes
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 05 human body systems
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?

lesson 6 06 infectious agents
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 07 classificatio n
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?
finished
Finished!

REMEMBER…

ALWAYS call your science teacher if you have any questions!
