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 oxygen into food
b) a cell process that uses energy from sunlight to convert water and glucose into food
c) a cell process that uses energy from sunlight to convert water and chlorophyll into food
d) a cell process that uses energy from sunlight to convert water and carbon dioxide into food
Plant cells contain a green pigment called chlorophyll. Chlorophyll has a role in the process of photosynthesis. What does chlorophyll do?
a) produces glucose from oxygen
b) produces oxygen from glucose
c) absorbs light energy from the sun
d) absorbs glucose from the plant
What is the food that plants produce during photosynthesis?
a) carbon dioxide
b) carbon dioxide
c) chloroplasts
d) glucose
How do organisms get the energy they need?
a) Plants get energy from fertilizers, and animals get energy by drinking water.
b) Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.
c) Plants do not require energy because they do not move, and animals get energy by performing exercise.
d) Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.
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) carbon dioxide
b) fat
c) oxygen
d) protein
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 absorbs sunlight’s green light and reflects other colors.
b) Chlorophyll converts sunlight to green light and absorbs its energy.
c) Chlorophyll reflects sunlight’s green light and absorbs the energy of the other colors.
d) Chlorophyll combines the different colors of sunlight and absorbs their energy.
Plants make their own food during photosynthesis. In what group do plants belong?
a) producers
b) consumers
c) chloroplasts
d) decomposers
What are the products of photosynthesis?
a) sugar and oxygen
b) sugar and carbon dioxide
c) chlorophyll and chloroplasts
d) chlorophyll and sugar
Green plants produce their own food during photosynthesis. Which of these statements about photosynthesis is TRUE?
a) Water is one product of photosynthesis.
b) Oxygen is one product of photosynthesis.
c) Chlorophyll is one product of photosynthesis
d) Carbon dioxide is one product of photosynthesis.
What is the result of cellular respiration?
a) food is made and stored in cells
b) energy is stored in the chemical bonds of food
c) sunlight is captured and used to make food
d) energy is released for use in cell functions
What are the reactants of photosynthesis?
a) carbon dioxide and water
b) sugar and water
c) glucose and oxygen
d) carbon dioxide and oxygen
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 oxygen and photosynthesis produces oxygen.
b) Cellular respiration uses carbon dioxide and photosynthesis does not.
c) Cellular respiration produces oxygen and photosynthesis does not.
d) Photosynthesis produces more glucose than cellular respiration does.
