Cell wall – only in plants
Chloroplast – only in plants (so animals
cannot make their own food)
Size of vacuole – plant cells have larger
vacuoles and provide support when full.
(turgor pressure)

4. What are organelles? Parts of the cell that have a specific
function within the cell
5. What is the function of the cell membrane? Controls what items can enter or leave
the cell
6. What is the function of the cell wall? Gives the cell membrane added
support/gives plant cells their box-like
shape
7. What is the function of the nucleus? Directs most all of the activities of the
cell
8. What is the function of the cytoplasm? The liquid part of the cell in which the
9. What organelle helps the cell manage
energy, by converting high energy glucose
into smaller energy units
10. What plant cell organelle uses radiant
energy from the Sun to turn carbon dioxide
and water into sugar?
11. What is the function of the vacuole?
other organelles float
mitochondria
chloroplasts
12. What is the function of ribosomes? produce proteins
13. What organelle breaks down and recycles
waste within the cell?
14 What organelle is a network of passages
that transports materials from one part of
the cell to another and provides a maze-like
assembly line for the production of proteins
and other substances?
Stores food, water, wastes, and other
materials for animal cells.
In plant cells it also helps to maintain
turgor pressure by storing water.
lysosomes
E.R.=endoplasmic reticulum
15 What is the function of Golgi bodies? Receives materials from E.R., packages
them, and distributes them to other
16 What makes the plant cell more rigid than
an animal cell?
parts of the cell.
Cell wall
17 Where is chromatin located? Inside the nucleus
18 Name the genetic materials found in the
nucleus.
1) DNA
2) Chromosomes
3) Genes
4) Chromatin
19 What is the cell theory? • All living things are composed of cells.
• Cells are the basic unit of structure and
function in living things.
• All cells are produced from other cells.
• All cells are similar because they do
things such as extracting energy from
food to help organisms survive.
20 What is the difference between structure Structure: the way parts are arranged
and function?
Function: the job something performs
21 What is a tissue? A group of cells that carry out a common
function

22 What is an organ? A group of tissues that carry out a
common function
23 What is an organ system? A group of organs that work together to
carry out a common function.
24 What is an organism? A group of organ systems that work
together to carry out a common
function.
25 Draw a flow map with the levels of
organization we studied from simplest to
most complex.
26 When new cells are created, it’s called
_______________.
27 How is the cell membrane similar to the
function of skin?
28 What is turgor pressure and which part of
the cell controls it?

What would have to happen to the cell
above to increase the turgor pressure?
If a scientist wanted to classify samples as
cells, tissues, organs, or systems what
would be the best way to organize this
information?
1. Bar Graph 2. Line Graph
CellsTissuesOrgansOrgan
SystemsOrganism
reproduction
it controls what enters and exits the cell
just like the skin gives off wastes and
takes in some essentials
Turgor pressure is the internal cell
pressure, against the cell wall, caused
when the vacuole is full of water help
plants to stand tall.
More water would have to enter the
vacuole. This would cause pressure on
the cell wall, making the plant more
rigid.
1. Bar graphs are used to compare
things between different groups.
2. Line graphs are used to track how
something changes over time.
3. A data table is a type of diagram that
organizes and represents a set of
data.
4. A tally chart is a chart that shows

3. Data Table 4. Tally Chart
32. How do you determine the overall total
magnification of the object being viewed
with the microscope?
how many there are of something or
how often something happens.
The Data Table would be best for
classifying samples into different
categories.
Multiply the magnification of the
eyepiece and the objective lens (the one
you placed over the specimen)
Determine the overall total magnification of the microscopes pictured below.
