7.12 (C) recognize levels of organization in plants and
animals, including cells, tissues, organs, organ
systems, and organisms;
7.12 (D) differentiate between structure and function in
plant and animal cell organelles, including cell
membrane, cell wall, nucleus, cytoplasm,
mitochondrion, chloroplast, and vacuole;
7.12 (F) recognize that according to cell theory all
organisms are composed of cells and cells carry on
similar functions such as extracting energy from food to
sustain life.
Two Classifications* of Cells
O Prokaryotic Cells
1st form of life
O Have NO nucleus – DNA is free
(called the “nucleloid”)
O ONLY form Unicellular
organisms (one-celled)
O Example: Bacteria (e. coli,
staph, salmonella)
O
O Eukaryotic Cells
Evolved from prokaryotes
O Have a nucleus with bundled
DNA
O Can form unicellular or multicellular organisms.
O Example: Amoebas, plants
animals, fungi, protists
O
*Note: There many TYPES of cells (skin, muscle, hair, sex,
etc.,); these are the two categories that ALL cells fall under! It is
the DNA within cells that controls what type of cell they will be.
Cell Organelles
Organelle & Function
*Cell Membrane: Outer
cell lining for protection
*Cytoplasm: Jelly-like
liquid that organelles float
in
*Nucleus: “Control center”
that contains organism’s
DNA
*DNA: The hereditary
material of organisms
*Vacuoles: Store nutrients
and waste
*Mitochondria: Jelly-bean
shaped producers of
energy (ATP) for cell
Plant
Organelles
PLANT-SPECIFIC organelles:
*Cell Wall: Gives plant cells
shape and structure (rigidity),
made of cellulose
*Chloroplast: Site where
photosynthesis in plant cells
occurs
*Large central vacuole: Stores
waste and water
EVALUATE:
What are some similarities
between plant and animal
cells?
What do you notice about the
vacuole of the plant cell?
Why do you think plants evolved
to have cell walls and
animals did not?

8th Grade Science
Monday, April 15, 2013
Draw and label an analogy of the cell to something you
are familiar with.
Possibilities: a school, an airport, a factory, a mall, the
solar system, etc.
Example: In a grocery store, the sliding doors are like
the cell membrane because it decides what goes in
and out of the store. The shelves are like the vacuoles
because they store materials. The workers are like the
mitochondria because they are the energy of the cell,
and the store manager is like the nucleus because they
tell the store and the people in it what to do.

7.12(B) identify the main functions of the systems of the human organism,
including the circulatory, respiratory, skeletal, muscular, digestive, excretory,
reproductive, integumentary, nervous, and endocrine systems;
8.10(A) recognize that the Sun provides the energy that drives convection
within the atmosphere and oceans, producing winds and ocean currents;
(B) identify how global patterns of atmospheric movement influence local
weather using weather maps that show high and low pressures and fronts
6.(9) Force, motion, and energy. The student knows that the Law of
Conservation of Energy states that energy can neither be created nor
destroyed, it just changes form. The student is expected to:
(A) investigate methods of thermal energy transfer, including conduction,
convection, and radiation;
(B) verify through investigations that thermal energy moves in a predictable
pattern from warmer to cooler until all the substances attain the same
temperature such as an ice cube melting

One day during cooking class, the teacher, Mrs. Jones, was revealing her
secrets for preparing perfect sauces. When she ordered us to the stoves to
prepare our assignments, she said,
“Now don’t forget to use wooden spoons.”
As I stirred my sauce, I contemplated the physics behind the mystery of the
wooden spoon and decided it must have something to do with heat
conduction. I approached Mrs. Jones to test my theory. “Why wooden
spoons?” I asked.
Do you know why Mrs. Jones wanted the class to use a wooden spoon?
