Heirarchy is the ranking of items in a particular order.
THROUGH Heirarchy is the ranking of items in a particular order. Organization of life-smallest unit of life to level of individual organization List the ORGANIZATION OF LIFE from smallest to biggest. atoms to molecules, to cells, to tissues, to organs, to organ systems, to organisms
9
Learning Target Students will investigate and explain the components of the scientific theory of cells (cell theory). Cell Theory consists of the following 3 parts: All cells come from preexisting cells Cells are the basic unit of life All living things are made of cells
10
b. What is an organism that is made up of just one cell?
Bellwork Cell Theory a. What is an organism? b. What is an organism that is made up of just one cell? c. What is an organism that is made up of more than one cell? An organism must carry out all the basic processes of life for it to survive (organization, metabolism, responsiveness, movements, and reproduction) STAY SAFE, EAT, REPRODUCE UNI- ONE (unicycle) MULTI – MANY (humans have TRILLIONS OF CELLS)
11
What is an organism? a. An organism is any living thing made up of one or more cells and able to carry out basic life functions. b. What is an organism that is made up of just one cell? b. Organisms made of just one cell are unicellular organisms c. What is an organism that is made up of more than one cell? c. Organisms made up of more than one cell are multicellular organisms
12
NOTES An organism must carry out all the basic processes of life for it to survive (organization, metabolism, responsiveness, movements, and reproduction) STAY SAFE, EAT, EXCRETE, REPRODUCE UNI- ONE (unicycle) MULTI – MANY (humans have TRILLIONS OF CELLS)
13
Unicellular organisms
Diatoms are a major group of algae, and are among the most common types of phytoplankton. Diatoms are unicellular, although they can form colonies in the shape of filaments or ribbons (e.g. Fragilaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stars (e.g. Asterionella). amoeba is any of several tiny, one-celled protozoa in the phylum. Amoebas live in freshwater and salt water, in soil, and as parasites in moist body parts of animals. BACTERIA -single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission Amoeba Bacteria (on a tooth!) Diatom

15
OUT What is a scientific theory?
A THEORY is a well-supported explanation about the natural world. It is based upon observation, experimentation and reasoning. It is supported by a large amount of evidence.
16
(The basic characteristics of all cells and organisms)
“Through” CELL THEORY (The basic characteristics of all cells and organisms) All organisms made up of one or more cells The cell is the basic unit of life All cells come from pre-existing cells
18
(The basic characteristics of all cells and organisms)
“Through” CELL THEORY (The basic characteristics of all cells and organisms) 1. All organisms are made up of one or more cells. 2. The cell is the basic unit of all organisms. All organisms made up of one or more cells The cell is the basic unit of life All cells come from pre-existing cells 3. All cells come from pre-existing cells.

IN Cell Theory day 2 Why is cell theory important?
-Cell theory is important because it is the basis for the study of life science. -It helps us understand the basic characteristics of all cells and organisms. Cell theory worksheet and video links

Day 2 Cell theory rap Goes with handout Cells Dividing
21
OUT What do all cells have in common? Microscopic, membrane surrounding the cell, they have parts inside the cell. Organisms inherit their DNA from their parents.
22
Learning target Compare and/or contrast the structures found in prokaryotic cells and in eukaryotic cells Compare and/or contrast the structures found in plant cells and in animal cells
23
IN 2-28-19 Prokaryote and Eukaryote
Which term describes one or more cells that carry out all the life processes needed to sustain life? organelle
24
What structures do cells have in common?
A cell membrane is a protective layer that covers a cell’s surface and controls materials moving into and out of the cell. The cytoplasm is the region inside the cell that includes all the organelles except for the nucleus.
25
Prokaryote vs Eukaryote
Amoebae Sisters Venn Diagram
26
What structures do cells have in common?
An organelle is a small body in the cytoplasm that is specialized to perform a specific function. The nucleus is a membrane-bound organelle that contains DNA. DNA, or deoxyribonucleic acid, is genetic material that provides instructions for all cell processes.
27
What are two types of cells?
Prokaryotes are single-celled organisms that do not have a nucleus or membrane-bound organelles. Prokaryotes’ DNA is in the cytoplasm. They have organelles without cell membranes called ribosomes. Some have flagella, or hairlike structures that help them move.
28
What are two types of cells?
Eukaryotes are organisms made up of cells that contain DNA in a nucleus, membrane-bound organelles, and ribosomes. Animals, plants, protists, and fungi are eukaryotes.
29
Where is the DNA located in prokaryotes? Membrane bound organelles
OUT Where is the DNA located in prokaryotes? Membrane bound organelles (Pro means NO Nucleus)
30
Learning target Compare and/or contrast the structures found in plant cells and in animal cells.
31
IN March 1, 2019 The organelle that contains DNA in eukaryotic cells is called a NUCLEUS

33
Day #4 - Bell work
34
Learning target Students will recognize and explore how cells of all organisms undergo similar processes to maintain homeostasis, including extracting energy from food, getting rid of waste, and reproducing.
35
Why is homeostasis important to a cell and organism?
IN: Why is homeostasis important to a cell and organism? What are the 3 basic needs of cells required for the cell to survive? (Or…what 3 life processes do cells need to maintain homeostasis?) Obtain Energy Eliminate Waste Reproduce
