“I Can” statement
1. State the parts of
the cell theory.
STUDENT RESPONSES
1.ALL ORGANISMS ARE MADE OF ONE OR MORE CELLS
2.THE CELL IS THE BASIC UNIT OF LIVING THINGS
3.ALL CELLS COME FROM EXISTING CELLS
2. State how different 1. HOOKE – FIRST TO DESCRIBE CELLS IN 1665
scientists contributed
2. VAN LEEUWENHOEK – LOOKED AT ANIMAL BLOOD CELLS AND
to the cell theory.
EUGLENA AND YEAST (BACTERIA)- SINGLE CELLED ORGANISMS
3. SCHLEIDEN – STUDIED PLANTS AND CONCLUDED PLANTS ARE
MADE OF CELLS
4. SCHWANN – STUDIED ANIMALS ARE CONCLUDED THAT ALL
ANIMALS ARE MADE OF CELLS
5 VIRCHOW - STATED THAT CELLS COME FROM EXISTING CELLS
(THIRD PART)
3. Describe the
differences between
single-celled and multicellular organisms.
SINGLE CELLED ORGANISMS ONLY CONTAIN THEIR ORGANELLES.
WHEN THAT CELL DIES, THE ORGANISM DIES. CAN BE
EUKARYOTES (WITH NUCLEUS) OR PROKARYOTES. (NO NUCLEUS)
MULTICELLULAR –MADE OF MANY CELLS. SOME MAY BE
SPECIALIZED, WHEN A CELL DIES, THE SYSTEM MAKES MORE.
CAN ONLY BE EUKARYOTES.(WITH NUCLEUS)

4. Explain the 4 levels 1.CELL – SMALLEST UNIT ABLE TO CARRY ON LIVING FUNCTIONS
of organization of living
2.TISSUE – MADE UP OF CELLS WITH A COMMON FUNCTION
things.
3.ORGAN – TISSUES WORKING TOGETHER TO PERFORM A COMMON
FUNCTION
4.ORGAN SYSTEM – GROUPS OF ORGANS WORKING TOGETHER TO
PERFORM A FUNCTION
5. Describe how
organs and organ
systems serve the
needs of cells.
THE RESPIRATORY SYSTEM BRINGS IN OXYGEN WHICH RED BLOOD
CELLS USE TO CARRY ON THEIR FUNCTIONS. MUSCLE CELLS ALSO
USE OXYGEN TO CONTRACT AND MOVE THE BODY (SKELETAL
SYSTEM)
THE BIG (ORGAN SYSTEMS) FUNCTIONS TO SERVE THE NEEDS OF
THE SMALL (CELLS)
6. Explain how
materials are passed in
and out of cells.
DIFFUSION: THE MOVEMENT OF ANYTHING INTO AND OUT OF
THE CELL (HIGHER CONCENTRATION TO LOWER CONCENTRATION)
THIS IS PASSIVE TRANSPORT.
OSMOSIS: THE MOVEMENT OF WATER INTO AND OUT OF THE
CELL THROUGH A SEMI PERMEABLE MEMBRANE. (HIGHER
CONCENTRATION TO LOWER CONCENTRATION) THIS IS PASSIVE
TRANSPORT.
ACTIVE TRANSPORT: THE MOVEMENT OF PARTICLES FROM LOWER
CONCENTRATION TO HIGHER CONCENTRATION REQUIRING ENERGY
TO BE USED FROM THE CELL (ATP) INCLUDES EXOCYTOSIS AND
ENDOCYTOSIS.
7. Describe how
nutrients are used by
cells.
NUTRIENTS ARE USED BY CELLS FOR BUILDING STRUCTURES AND
MAKING SPECIALIZED MOLECULES LIKE ATP (ENERGY)

8. Explain the basic
functions of cells.
Name ______________________
Hour _____
CELLS MAKING UP AN ORGAN/ORGAN SYSTEM ARE ALL THE SAME,
THEY WORK TOGETHER TO PERFORM A SIMILAR FUNCTION, AND
BEGAN AS UNSPECIALIZED CELLS THAT WERE ALL GIVEN THE
SAME “PROGRAMMING” INSTRUCTIONS. THEY LIVE, GROW,
REPRODUCE, AND GET RID OF WASTE.
9. Describe the
process and function of
cellular respiration.
DRAW AND LABEL (USE YOUR NOTES AND BOOK).
THIS IS THE PROCESS OF PRODUCING ENERGY WITH OXYGEN
RESPIRATION HAPPENS IN THE MITOCHONDRIA (OF
MULTICELLULAR ORGANISMS). USES OXYGEN, GLUCOSE AND
MAKES ATP, CARBON DIOXIDE AND WATER. THE MAIN PURPOSE
IS TO PRODUCE ENERGY (ATP) FOR THE CELL.
C6H12O6 + 6O2  6CO2 + 6H2O + ENERGY (ATP)
P.42 IN BOOK
10. Describe the
process and function of
fermentation.
THE PROCESS OF PRODUCING ENERGY WITHOUT OXYGEN, IT USES
11. State where
photosynthesis takes
place.
INSIDE THE CHLOROPLASTS OF GREEN PLANTS (EVEN THOSE IN

growth occurs in multicellular organisms.
YOUR BODY PRODUCED MORE CELLS THAN DIED. YOUR BODY USED
CO2 IN MUSCLE CELLS LACTIC ACID IS PRODUCED AS A BIPRODUCT.
THE WATER)
THE EXTRA CELLS AND GREW LARGER. THE CELLS UNDERGO
MITOSIS TO GROW.

13. Explain how
growth occurs in single
celled organisms.
Name ______________________
Hour _____
IN A SINGLE CELL, THE CELL SIZE SIMPLY GROWS LARGER (THE
SURFACE AREA AND VOLUME OF THE CELL GROW). IF THE
SURFACE AREA AND VOLUME DON’T GROW IN THE SAME
PROPORTION, THE CELL WILL DIE.
14. Compare large
and small multi-cellular
organisms (in terms of
cell numbers).
THE LARGER THE ORGANISM, THE MORE CELLS IT HAS. THE CELLS
15. Describe how
unspecialized cells
(stem cells) become
specialized cells.
STEM CELLS WAIT FOR A PROTEIN SIGNAL TO TELL THEM WHAT
ARE NO LARGER, ONLY MORE OF THEM.
TYPE OF CELLS TO BECOME. THEY GO FROM NO DIRECTION
(UNSPECIALIZED) TO HAVING DIRECTIONS (SPECIALIZED). THIS
IS KNOWN AS DIFFERENTIATION.
16. Explain
differentiation.
WHEN CELLS RECEIVE PROTEIN SIGNALS, THEY THEN BECOME
“DIFFERENT” THAN OTHER CELLS THAT HAVE OTHER JOBS. LIVER
CELLS FUNCTION TOGETHER TO MAINTAIN LIVER FUNCTIONS.
BRAIN CELLS WORK TOGETHER TO MAINTAIN BRAIN FUNCTION
AND SO ON.
17. Explain what
sexually reproduced
organisms begin as
THEY BEGIN AS A FERTILIZED EGG (STEM CELL). SEXUAL
REPRODUCTION PROVIDES THE OPPORTUNITY TO HAVE COMPLEX
ORGANISMS. CELLS, TISSUES, ORGANS AND ORGAN SYSTEMS
DEVELOP WITHIN THESE TYPES OF ORGANISMS MAKING SYSTEMS
SPECIALIZED WITH A SPECIFIC JOB.

18. Describe the
process and products
of photosynthesis.
DRAW AND LABEL BELOW.
OCCURS IN GREEN PLANTS. USES CARBON DIOXIDE, LIGHT, AND
WATER AND PRODUCES GLUCOSE AND OXYGEN. THE MAIN
PURPOSE IS MAKE FOOD FOR THE PLANT (GLUCOSE). THIS TAKES
PLACE IN THE CHLOROPLAST OF PLANT CELLS.
6CO2 + 6H2O + LIGHT ENERGY  C6H12O6 + 6O2
19. List common
plants that contain
proteins,
carbohydrates, and fat
and oils.
PROTEINS
CARBOHYDRATES
FATS & OILS
LEGUMES (BEANS)
SUGAR CANE OR
OLIVE OIL (OLIVES),
NUTS (PEANUTS,
BEETS, POTATOES,
VEGETABLE OIL,
ALMONDS,
FRUITS, WHEAT OR
PEANUT OIL,
WALNUTS)
GRAIN PRODUCTS
AVOCADO
(BREAD, PASTA,
CRACKERS), VEGGIES
20. List the elements
that make up proteins,
carbohydrates and
fats.
21. Explain the
sources necessary for
aquatic plants to do
photosynthesis.
Proteins
Carbohydrates
Fats & Oils
CARBON,
HYDROGEN,
OXYGEN, NITROGEN
CARBON,
HYDROGEN, OXYGEN
CARBON, HYDROGEN,
OXYGEN
LIGHT, CARBON DIOXIDE AND WATER. AQUATIC PLANTS GET
THEIR CO2 FROM THE ORGANISMS THAT LIVE IN THE WATER
(LIKE FISH) THAT GIVE OFF CO2. THEY PERFORM
PHOTOSYNTHESIS JUST LIKE LAND PLANTS.

23. Explain the
purpose of
photosynthesis.
TO MAKE FOOD FOR PLANTS (IN THE FORM OF GLUCOSE). THEY
USE THIS FOOD FOR THEIR LIFE FUNCTIONS. GROW, MAKING
FLOWERS OR SEED, ECT.
24. Describe how you
can tell that plants use
and store food.
YOU CAN TELL THE PLANTS ARE USING THE FOOD THAT THEY
STORE BECAUSE THEY ARE ABLE TO GROW AND REPRODUCE. THE
STORAGE PLACE (ROOTS) WILL GROW SMALLER AS THE FOOD IS
USED.
25. State the formula
for photosynthesis.
26. Describe the role
light plays in
photosynthesis.
6CO2 + 6H2O + LIGHT ENERGY  C6H12O6 + 6O2
LIGHT BREAKS THE CARBON DIOXIDE MOLECULES AND THE WATER
MOLECULES SO THAT THE REACTION OF PHOTOSYNTHESIS CAN
OCCUR.

27. Describe the
offspring of asexual
reproduction.
Name ______________________
Hour _____
OFFSPRING OF ASEXUAL REPRODUCTION ARE IDENTICAL TO THE
PARENTS. THEY ARE FORMED FROM ONLY ONE CELL AND ARE
USUALLY SINGLE CELLED ORGANISMS OR SINGLE CELLS WITHIN
YOUR BODY.
28. Describe the
offspring of sexual
reproduction.
OFFSPRING OF SEXUAL REPRODUCTION CONTAIN HALF THE
HEREDITY MATERIAL FROM EACH PARENT. THESE ORGANISMS ARE
USUALLY MORE COMPLEX AND ARE DIVERSE (DIFFERENT) FROM THE
REST OF THE POPULATION. THEY DON’T LOOK EXACTLY LIKE
EITHER PARENT BUT ARE A COMBINATION OF BOTH.
29. Draw how
pollination and
fertilization (sexual
reproduction) occur in
flowers.
DRAW AND LABEL BELOW.
DRAWINGS WILL VARY. MAIN IDEAS:
POLLINATION IS THE TRANSFER OF POLLEN FROM THE ANTHER
(MALE STRUCTURE) TO THE STIGMA (THE TOP OF THE FEMALE
STRUCTURE). ONCE THIS TRANSFER HAS OCCURRED, THEN
POLLINATION HAS OCCURRED.
FERTILIZATION OCCURS WHEN THE SPERM (LOCATED WITHIN THE
POLLEN GRAIN) TRAVELS THROUGH THE FEMALE STRUCTURE AND
FERTILIZES THE EGG FORMING A SEED. AT THAT POINT,
FERTILIZATION HAS OCCURRED.
THIS IS SEXUAL REPRODUCTION IN PLANTS. ANY QUESTION
WITH A “TRANSFER OF POLLEN, OR FORMING A SEED FALLS UNDER
THIS CATEGORY.”

30. List examples of
organisms that
reproduce asexually.
MOST OF YOUR BODY’S CELLS (MITOSIS), PROTISTS LIKE AMOEBA,
31. Explain the
advantages and
disadvantages of
asexual reproduction.
ADVANTAGES: PRODUCES LARGE NUMBERS OF OFFSPRING, NO
PARAMECIUM, PLANTS FORMING WITHOUT THE EXCHANGE OF
POLLEN (RUNNERS) , OR BACTERIA BINARY FISSION
NEED TO FIND A MATE, POSITIVE TRAITS ARE ALWAYS COPIED
AND REPRODUCED
DISADVANTAGES: NEGATIVE TRAITS ARE ALWAYS COPIED AND
REPRODUCED, NO VARIATIONS WITHIN THE SPECIES
32. Explain the
ADVANTAGES: VARIATIONS IN GENETIC MATERIAL MAY HELP
advantages and
SPECIES SURVIVE, NEGATIVE TRAITS ARE NOT ALWAYS
disadvantages of sexual
reproduction.
REPRODUCED
DISADVANTAGES: FEWER OFFSPRING, NECESSARY TO FIND A
MATE, CAN COMBINE TO FORM NEGATIVE TRAITS THAT ARE NOT
PRESENT IN EITHER PARENT.
