Chloroplasts
Animal cells have all of the following EXCEPT
Cytoplasm
The nucleus includes all of the following structures EXCEPT
Organ
The human brain is an example of a
Ribosomes
Which cell structures are sometimes found attached to the endoplasmic reticulum?
Exocytosis
Which process always involves the movement of materials from inside the cell to outside the cell?
Endocytosis
Which of the following is an example of active transport?
A nucleus
The difference between prokaryotic and eukaryotic cells involves the presence of
Active transport
In the experiment sucrose probably entered the cells by mean of
Took in sucrose more slowly
The graph shows that as the concentration of sucrose increased from 10 to 30 mmol/L the plant cells
was constant between 30 and 40 mmol/L.
Based on the graph, the rate of sucrose uptake
Will take in water and swell up and burst
What would you expect to happen if you places a typical cell in fresh water
Chapter 8
make their own food from carbon dioxide and water
Autotrophs differ from heterotrophs because they
NADPH
The principal pigment in plants is
sugars + O2 light H20 + CO2
Which of the following correctly summarizes the process of photosynthesis
Green
The color of light that is LEAST useful to a plant during photosynthesis is
Absorption of light energy
The first step in photosynthesis is the
Oxygen
In a typical plant all of the following facts are necessary for photosynthesis EXCEPT
yellow-green
Which pigment traveled the shortest distance
contain several pigments
A valid conclusion that can be drawn fro this information is that spinach leaves
chloroplasts
In which organelle would MOST of these pigments be found
Light is absorbed by electrons in pigments
Describe how high energy electrons are ultimately responsible for driving the photosynthetic reactions
