Plant cells that are flooded with salt water will decrease the size of their central vacuoles, and their cell membranes will shrink away from the cell walls. What is this an attempt to do?
a
store some water and restrict salt water from entering the cells
b
store salt inside the cell for cell processes
c
enable the plant to survive in a drought condition
d
release all the water from the cells
The correct answer is a) store some water and restrict salt water from entering the cells.
In a drought, sufficient water is not available for the uptake of water into trees. This directly affects the process of _____________________. Without this process, ample oxygen is not placed into the atmosphere for living things to undergo _______________________.
a
photosynthesis, respiration
b
respiration, photosynthesis
c
carbon dioxide, oxygen
d
oxygen, carbon dioxide
The correct answer is a) photosynthesis, respiration.
Plants produce glucose in order to
a
move.
b
get sunlight.
c
make energy.
d
turn green.
The correct answer is c) make energy.
What are the reactants in the equation for cellular respiration?
a
glucose and oxygen
b
carbon dioxide and water
c
oxygen and lactic acid
d
water and glucose
The correct answer is a) glucose and oxygen.

The diagram shows a cross section of a eukaryotic cell.
How do the nucleus and ribosomes work together?
a
The ribosomes perform chemical reactions that supply the nucleus with needed nutrients.
b
The nucleus creates proteins and lipids that the ribosomes then transport to other organelles.
c
The nucleus sorts and distributes the genetic information it receives from the ribosomes.
d
The ribosomes build proteins based on the genetic instructions they receive from the nucleus.
The correct answer is d) The ribosomes build proteins based on the genetic instructions they receive from the nucleus.
Which of the following organelles specializes in producing energy for the cell?
a
endoplasmic reticulum
b

The correct answer is b) mitochondria.
The diagram below shows the structure of a bacterial cell.
Which of the following distinguishes this bacterial cell from eukaryotes?
a
The bacterial cell is a unicellular organism, and all eukaryotes are multicellular.
b
DNA in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus.
c
Ribosomes are found in the cytoplasm of the bacterial cell, and eukaryotes do not have ribosomes.
d
The bacterial cell has both a cell membrane and a cell wall, and eukaryotes have only cell membranes.
The correct answer is b) DNA in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus.
Plant cells have large membrane bound spaces in which water, waste products, and nutrients are stored. These spaces are known as
a
vacuoles
b
chloroplasts
c
Golgi bodies
d

The correct answer is a) vacuoles.
How do the Golgi apparatus and vesicles interact in an animal cell?
a
The Golgi apparatus synthesizes proteins, and the vesicles package the proteins for transport in the cell.
b
The Golgi apparatus degrades proteins, and the vesicles synthesize replacement proteins in the cell.
c
The Golgi apparatus transports proteins, and the vesicles control the transportation of the proteins in the cell.
d
The Golgi apparatus packages proteins, and the vesicles transport the packages to various locations in the c
The correct answer is c) The Golgi apparatus transports proteins, and the vesicles control the transportation of the proteins in the cell.
Which of the following statements is NOT part of the "Cell Theory"?
