1.
The purpose of the cell wall in plants is to -
a)
Store DNA and proteins for the cell.
b)
Control what crosses into and out of the cell.
c)
Provides structure and support for the cell.
d)
Send chemical signals to neighboring cells.
2.
Plant cells are different from animal cells because they are usually -
a)
Circular in shape, contain lysosomes, and have mitochondria.
b)
Circular in shape, contain ribosomes, and have centrioles.
c)
Rectangular in shape, contain a small vacuole, and have mitochondria.
d)
Rectangular in shape, contain a large vacuole, and have chloroplasts.
3.
Which part of a plant cell contains chlorophyll?
a)
Chloroplast
b)
Nucleus
c)
Vacuole
d)
Cytoplasm
4.
Animal and plant cells have all of the following EXCEPT -
a)
Chloroplasts to carry out photosynthesis.
b)
Vacuoles to store water and nutrients.
c)
Mitochondria to form chemical energy.
d)
A nucleus with DNA to replicate cells.
5.
Which organelle requires light in order to perform its function?
a)
A centriole, because it performs cell division that is encouraged by light.
b)
A Golgi apparatus, because it packages proteins by light triggered reactions.
c)
A mitochondrion, because it performs respiration with its light membrane.
d)
A chloroplast, because it performs photosynthesis with its light absorbing pigments.
6.
There are many different types of cells with many different types of cellular structures and functions. Which of these structures is found in Plant and Animal cells?
a)
Chloroplast
b)
Cell Wall
c)
Nucleus
d)
Chlorophyll
7.

a)
1 Vacuole
b)
2 Chloroplast
c)
3 Mitochondria
d)
4 Golgi apparratus
8.
Which structure regulates the movement of substances in and out of the plant cell?
a)
1
b)
2
c)
6
d)
7
9.
Which of the following best identifies a similarity of organs in an organism to organelles in a cell?
a)
Both are found in single-celled organisms.
b)
Both carry out chemosynthetic reactions.
c)
Both are made of tissues.
d)
Both carry out specific functions.
10.
A damaged cell is having trouble breaking down and removing unwanted waste from the cell after the cell has metabolized. Which organelle is most likely responsible?
a)
Lysosome
b)
Mitochondria
c)
Cytoplasm
d)
Ribosome
11.
The term "cell" was coined by Robert Hooke. Why were cells given this name?
a)
They block substances from crossing their cell membranes.
b)
They are small individual compartments of life.
c)
They are all rectangular in shape.
d)
They lock toxins inside the cell.
12.
Based on the Cell Theory, -
a)
Only multicellular organisms have cells.
b)
All cells contain tissues and organs.
c)
Single-celled organisms develop spontaneously.
d)
The cell is the basic unit of life.
13.
In the 1830's, two German Scientists, Theodor Schwann and Matthias Schleiden, came up with a remarkable new scientific theory called the "Cell Theory". The cell theory had three basic basic parts. In 1855, German scientist, Rudolf Virchow , proposed that the last part of the theory that stated that cells spontaneously generate was incorrect. Virchow issued a bold statement: "Omnis cellula e cellula." As it turns out, Virchow was quite right. What is the best translation of Virchow's statement about the cell theory?
a)
All cells come from other cells.
b)
All cells begin as bacterial cells.
c)
All cells are unrelated to other cells.
d)
All cells can become any cell.
14.
In 1665, Robert Hooke used a compound microscope to observe the natural world by looking at a thin slice of cork. The picture shows what he saw. Based on the cell theory, what can be concluded from what Robert Hooke saw?
a)
Plants contain a unique mesh of fiber in their tissues.
b)
Living organisms are composed of one large mass.
c)
Living organisms are made of tiny individual units.
d)
Plants contain cellulose in their cell walls.
15.
Unlike nonliving things, all living things are made of-
a)
Water
b)
Atoms
c)
Cells
d)
Energy
100 %
