Which cell is a plant cell? CELL B
Which cell is an animal cell? CELL A
Which cells are prokaryote? NONE
Which cells are eukaryote? ALL – A, B, AND C
5.During photosynthesis, what gas do plants release? OXYGEN
6.During cellular respiration, what do plant and animal cells use to produce energy
from food? (What are the raw materials of cellular respiration?)
GLUCOSE AND OXYGEN
7. Why is photosynthesis important to all living things on earth? ALL LIVING
THINGS MUST BREATHE OXYGEN AND ALL CONSUMERS MUST EAT
PLANTS OR SOMETHING THAT ATE PLANTS
8. What is an organelle found in plant cells that captures energy from sunlight?
CHLOROPLAST
9. What are the raw materials needed for photosynthesis?
CARBON DIOXIDE, WATER, LIGHT ENERGY
10. By what process do small molecules move into the cell going from areas of high
concentration to areas of low concentration?
PASSIVE TRANSPORT OR DIFFUSION
11. The process by which water moves across a cell membrane is called __.
OSMOSIS
12. Where does cellular respiration primarily occur within a cell?
MITOCHONDRIA
13. The energy that starts the process of photosynthesis comes from where?
SUNLIGHT
14. By which process do plants make their own food from carbon dioxide and
water?
PHOTOSYNTHESIS
15. What gas do plants take in to make food?
CARBON DIOXIDE
Light energy
6CO2 + 6H2O
C6H12O6 + 6O2
16. Analyze the above equation for photosynthesis and identify the products of
photosynthesis.
GLUCOSE AND OXYGEN
17.Passive Transport – describe & tell three types
WHEN MOLECULES GO FROM HIGH TO LOW THROUGH A CELL
MEMBRANE, DOES NOT USE ENERGY
TWO TYPES ARE 1-DIFFUSION- MOLECULES OTHER THAN WATER
AND
2-OSMOSIS – MOVEMENT OF WATER MOLECULES
3. Facilitated diffusion uses protein channels to move molecules across the
cell membrane.
18.Active transport – describe & tell two types
WHEN MOLECULES TRAVEL FROM LOW TO HIGH CONCENTRATION
THROUGH A CELL MEMBRANE, USES ENERGY
TWO TYPES ARE 1- ENDOCYTOSIS – GOING INTO A CELL
2- EXOCYTOSIS –GOING OUT OF A CELL
***See Handout for visual
Write in the names of the organelles in the space next to their descriptions
below:
CELL WALL
CELL MEMBRANE
NUCLEUS
RIBOSOMES
MITOCHONDRIA
CHLOROPLAST
GOLGI
LYSOSOMES
ENDOPLASMIC RETICULUM
EUKARYOTE
PROKARYOTE
DNA
NUCLEUS
19.
a rigid structure that gives support to a cell
20.
a barrier that encloses and protects the cell
21.
a large organelle that produces and stores the cell’s DNA, the
control center
22.
organelles that make proteins
23.
an organelle that functions as the main power source of a cell,
breaking down sugar to produce energy
24.
organelles in which photosynthesis takes place.
25.
the organelle that packages and distributes proteins
26.
organelles that contain digestive enzymes
27.
pathways for proteins and other material inside the cell.
Ribosomes can be found here.
28.
a cell with a nucleus (with a membrane-bound organelle)
29.
a cell without a nucleus (without a membrane bound organelle)
30.
genetic material in cells
31.
where DNA is stored
Answer the following questions. Be sure to stay away from words like, it,
stuff, and they. Use the back of the paper if you need more space.
32. Compare and contrast the functions of the cell wall and the cell membrane.
BOTH PROTECT THE CELL, CELL MEMBRANE IS FLEXIBLE, CELL WALL IS
RIGID, CELL WALL IS PLANT CELLS ONLY, CELL MEMBRANE IS IN BOTH
PLANT AND ANIMAL CELLS
33. How are osmosis and diffusion different from each other?
OSMOSIS CARRIES WATER MOLECULES ONLY. DIFFUSION CARRIES ALL
OTHER TYPES OF MOLECULES
34.What are three differences between plant cells and animal cells?
PLANT CELLS HAVE A CELL WALL, CHLOROPLASTS, AND A LARGE
VACUOLE. ANIMAL CELLS DO NOT HAVE CHLOROPLASTS OR CELL WALL
AND THEIR VACUOLES ARE SMALL
ALSO, ANIMAL CELLS ONLY HAVE LYSOSOMES
35. Explain the process of photosynthesis and then respiration starting with the
raw material through how the cell gets energy from the product.
IN PHOTOSYNTHESIS, PLANTS USE WATER, CARBON DIOXIDE AND
LIGHT FROM THE SUN TO MAKE GLUCOSE (FOOD) AND OXYGEN. IN
CELLULAR RESPIRATION, ORGANISMS USE GLUCOSE AND OXYGEN TO
MAKE ENERGY. THE OTHER PRODUCTS ARE CARBON DIOXIDE AND
WATER. THEY ARE OPPOSITE PROCESSES.
