Terms in this set (47)

Animal cells have all of the following EXCEPT
Chloroplasts
The nucleus includes all of the following structures EXCEPT
Cytoplasm
The human brain is an example of a(n)
organ
Which cell structures are sometimes found attached to the endoplasmic reticulum?
Ribosomes
Which process always involves the movement of materials from inside the cell to the outside the cell?
Osmosis
Which of the following is an example of active transport?
Endocytosis
The difference between prokaryotic and eukaryotic cells involves the presence of
A nucleus
In this experiment, sucrose probably entered the cells by means of
Osmosis
The graph shows that as the concentration of sucrose increased from 10-30 mmol/L, the plant cells
Took in sucrose more slowly

Based on the graph, the rate of sucrose uptake
Was constant between 30 and 40 mmol/L
Autotrophs differ from heterotrophs because they
Make their own food from carbon dioxide
The principal pigment in plants is
Chlorophyll
Which of the following is NOT produced in the light-dependent reactions of photosynthesis?
Sugars
Which of the following correctly summarizes the process of photosynthesis?
H2O + CO2 light -----→ sugars + O2
The color of light that is LEAST useful to a plant during photosynthesis is
Green
The first step in photosynthesis is the
Absorption of light energy
In a typical plant, all of the following factors are necessary for photosynthesis EXCEPT
Oxygen
Which pigment traveled the shortest distance?
Yellow-green
A valid conclusion that can be drawn from this information is that spinach leaves
Contain several pigments
In which organelle would MOST of these pigments be found?
Chloroplasts
What raw materials are needed for cellular respiration?
Glucose and oxygen
Pyruvic acid is broken down into carbon dioxide in a series of reactions
During the Krebs cycle
Which substance is needed to begin the process of glycolysis?
ATP
In eukaryotic cells, MOST of cellular respiration takes place in the
Mitochondria
Which substance is broken down during the process of glycolysis?
Glucose
The human body can use all of the following as energy sources EXCEPT
Alcoholic fermentation
During cellular respiration, which of the following are released as byproducts?
CO2 and H2O
Which of the following is an aerobic process?
The Krebs cycle
According to the graph, what is the relationship between the rate of fermentation and temperature?
The rate of fermentation increases with temperature at first, and then it rapidly decreases
Which statement could explain the data shown in the graph?
The yeast cannot survive above 30°C
Which statement is true regarding a cell's surface area-to-volume ratio?
Smaller cells will have greater surface area-to-volume ratio
Which of the following is NOT an advantage of asexual reproduction?
Increases genetic diversity
At the beginning of cell division, a chromosome consists of two
Chromatids
What regulates the timing of the cell cycle in eukaryotes?
Cyclins
The period between cell divisions is called
Interphase
A cell enters anaphase before all of its chromosomes have attached to the spindle. This may indicate that the cell is not responding to
Internal regulators
"How chromosomes migrate during cell division" is a
hypothesis
The diagrams show that chromosomes move to the poles of the cell as the spindle fibers
Shorten on the chromosome side of the mark
A valid conclusion that can be drawn from this experiment is that the spindle fibers break down
At the centrioles
What happens to the chromosome number during meiosis?
it halves
Which ration did Mendel find in his F2 generation?
3 : 1
During which phase of meiosis is the chromosome number reduced
Telophase II
Two pink-flowering plants are crossed. The offspring flower as follows: 25% red, 25% white, and 50% pink. What pattern of inheritance does flower color in thee flowers follow?
incomplete dominance
Which of the following is used to construct a gene map?
Recombination rate
Alleles for the same trait are separated from each other during the process of
Meiosis I
Which of the following is NOT one of Gregor Mendel's principles?
Crossing-over occurs during meiosis
How many map units apart are genes A and D?
8
Which gene map best reflects the student's data?
C 5 B 12 A 8 D
