A review of topics discussed in a 7th grade unit on cells.

1. S7L2. Students will describe the structure and function of cells, tissues,
organs, and organ
systems.
a. Explain that cells take in nutrients in order to grow and divide and to
make needed
materials.
b. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts,
mitochondria) to basic cell functions.
c. Explain that cells are organized into tissues, tissues into organs, organs
into systems, and systems into organisms.

2. EQ: How can I summarize what I have
learned about cells?

4. All cells have a cell membrane and contain
cytoplasm.
Eukaryotic, prokaryotic, plant,
and animal cells ALL contain
cytoplasm surrounded by a cell
membrane (pg. 38).

5. Prokaryotic cells have many membrane
bound structures.
Eukaryotic cells have
membrane bound
structures.
Prokaryotic cells do not
(pg.39).

6. What is the structure that surrounds all
cells, letting some substances in and out?
The Cell Membrane allows
very small molecules, such
as oxygen molecules, to
pass through it (pg. 38).

7. The jelly-like substance in a cell that holds
all organelles in place is called:

8. Tough outer structure that gives
some cells their box-like shape:
Cytoplasm
Chloroplasts
Cell Armor
Cell Membrane
Cell Wall
Cell Wall
(pg. 39)

9. The nucleus is the boss of the cell.
The Nucleus directs all cell
activities and is usually the
largest organelle in the cell
(pg.40).

10. Organelle which stores and releases
energy for the cell to use:
Vesicles
Golgi Body
Cytoplasm
Nucleus
Mitochondria
Mitochondria
(pg. 42).

11. What are the organelles called that
produce proteins within the cell?
Ribosomes are created
in the nucleus and
produce proteins for
the cell (pg. 42).

12. Ribosomes are found in the Smooth
Endoplasmic Reticulum.
Some ribosomes are found in
the Rough Endoplasmic
Reticulum, and some float
freely in the cytoplasm of the
cell (pg. 42).

13. The organelle responsible for the
production of some hormones and lipids:

14. Organelle that sorts substances and
packages them into vesicles for
transport:
Smooth ER
Vacuole
Mitochondria
Yupeaestacin
Golgi Body
Golgi Body (pg.
43).

16. Organism
The Cell
Tissue
Organ
Organ System
• Several systems work
together to perform
life functions (pg. 45)
• Two or more tissues
that work together
(pg. 45)
• Smallest Unit of Life
(pg. 38)
• A group of cells that
work together to do
one job (pg. 45)
• Group of organs
that work together
(pg. 45)

17. How the cell
moves substances
into and out of
the cell.

18. Cellular transport that requires no
input of energy:
Funnels
Protein Transport
Membrane Transport
Active Transport
Passive Transport
Passive Transport
(pg. 74)

19. When substances move from an area of
high concentration to an area of low
concentration, this is called:
Diffusion:
When substances naturally move from an
area of high concentration to an area of
low concentration across the cell
membrane (pg. 75).

20. Osmosis is the diffusion of glucose (sugar).
Osmosis is the diffusion of
water (pg. 76).

21. What is it called when there is no longer
and area of high or low concentration on
either side of the cell membrane?

22. When a substance is too large to move
across the cell membrane, it must rely
on transport proteins in a process
called:
Helper Transport
Transport Diffusion
Active Diffusion
Helper Diffusion
Facilitated Diffusion
Facilitated Diffusion (pg. 77)

23. Active transport requires energy.
Active transport requires energy
because it involves moving
substances from low to high
concentrations.

24. When a cell uses the cell membrane to pull
a substance into the cell:

25. When a cell releases substances outside of
the cell using vesicles:

26. All activities in an organism involve
chemical reactions.
The total of all chemical
reactions in an organism
are called metabolism
(pg. 81).

27. Organelles which produce glucose (food) in
most plant cells.
6 Carbon
dioxide
molecules
1 Water
molecule
Light
energy
1
Glucose/
sugar
molecule
6 Oxygen
molecules

28. The process in which animal cells break
down food for energy is called:
Assisted Transaction
Active Transport
Cellular Production
Cellular Globalism
Cellular Respiration
Cellular
Respiratio
n (pg. 83).
