Photosynthesis And Cellular Respiration
Test Description: FCAT Practice
Instructions: Answer all questions to get your test result.
1) Green plants and algae make their own food through photosynthesis. What is photosynthesis?
A
a cell process that uses energy from sunlight to convert water and chlorophyll into food
B
a cell process that uses energy from sunlight to convert water and oxygen into food
C
a cell process that uses energy from sunlight to convert water and carbon dioxide into food
D
a cell process that uses energy from sunlight to convert water and glucose into food
2) Plant cells contain a green pigment called chlorophyll. Chlorophyll has a role in the process of photosynthesis. What does chlorophyll do?
A
absorbs glucose from the plant
B
produces glucose from oxygen
C
absorbs light energy from the sun
D
produces oxygen from glucose
3) What is the food that plants produce during photosynthesis?
A
carbon dioxide
B
chloroplasts
C
carbon dioxide
D
glucose
4) How do organisms get the energy they need?
A
Plants do not require energy because they do not move, and animals get energy by performing exercise.
B
Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.
C
Plants get energy from fertilizers, and animals get energy by drinking water.
D
Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.
5) During cellular respiration, an organism’s cells break down glucose to provide energy for life activities. Which of these substances is also produced during cellular respiration?
A
fat
B
protein
C
carbon dioxide
D
oxygen
6) Sunlight includes all the wavelengths of visible light. A person’s eye sees the different wavelengths of light as different colors. Why does chlorophyll cause leaves to look green?
A
Chlorophyll combines the different colors of sunlight and absorbs their energy.
B
Chlorophyll absorbs sunlight’s green light and reflects other colors.
C
Chlorophyll reflects sunlight’s green light and absorbs the energy of the other colors.
D
Chlorophyll converts sunlight to green light and absorbs its energy.
7) Plants make their own food during photosynthesis. In what group do plants belong?
A
consumers
B
producers
C
decomposers
D
chloroplasts
8) What are the products of photosynthesis?
A
sugar and carbon dioxide
B
sugar and oxygen
C
chlorophyll and sugar
D
chlorophyll and chloroplasts
9) Green plants produce their own food during photosynthesis. Which of these statements about photosynthesis is TRUE?
A
Chlorophyll is one product of photosynthesis
B
Carbon dioxide is one product of photosynthesis.
C
Oxygen is one product of photosynthesis.
D
Water is one product of photosynthesis.
10) What is the result of cellular respiration?
A
sunlight is captured and used to make food
B
energy is released for use in cell functions
C
food is made and stored in cells
D
energy is stored in the chemical bonds of food
11) What are the reactants of photosynthesis?
A
glucose and oxygen
B
sugar and water
C
carbon dioxide and oxygen
D
carbon dioxide and water
12) During cellular respiration, cells break down food to release energy. During photosynthesis, cells produce food in the form of glucose. What is one difference between these two processes?
A
Cellular respiration uses carbon dioxide and photosynthesis does not.
B
Cellular respiration uses oxygen and photosynthesis produces oxygen.
C
Cellular respiration produces oxygen and photosynthesis does not.
D
Photosynthesis produces more glucose than cellular respiration does.
