The Chloroplast Flashcards
Which of the following statement does not support the function of a chloroplast?
A. Chloroplast is responsible for enabling photosynthesis to occur so
that plants can convert sunlight into chemical energy.
B. Chloroplast is an organelle unique to plant cells that contains
chlorophyll
C. Chloroplast contains most reactions during photosynthesis
D.Chloroplasts are minor sources of energy for plants
D. Chloroplasts are minor sources of energy for plants
In which structure of the chloroplast does the chlorophyll contained?
A. Thylakoid
B. Stroma
C. Mesophyll
D.Granum
A. Thylakoid
Comparable to mitochondria, which serves as a “powerhouse” of the cell, a chloroplast makes the availability of energy for plants accessible except:
A. It generates large quantities of energy
B. It stores calcium for cell signaling activities
C. It is responsible also for transporting molecules
D. It provides its own food that then gets used to power the organism.
A. It generates large quantities of energy
In which two layers of the leaf are most active chloroplasts found?
A. Palisade and spongy mesophyll
B. Epidermis and stomata
C. Xylem and Phloem
D. Roots and Spongy Mesophyll
A. Palisade and spongy mesophyll
Chlorophyll, a very important pigment for food production among plants
dominates green as its color. What is the reason for this?
A. It absorbs green wavelengths
B. It reflects green wavelengths of light
C. An optical phenomena caused by transmission of light
D. It absorbs blue and yellow wavelengths combined to be green as a result
D. It absorbs blue and yellow wavelengths combined to be green as a result
What process takes place in the chloroplast turning light energy into food?
Photosynthesis
Which of the following controls which molecules can enter or leave the chloroplast?
A. outer membrane
C. stroma
B. inner membrane
D. thylakoids
A. outer membrane
Which of the following is the collection of sacks containing chlorophyll?
A. stroma
C. pigments
B. thylakoids
D. lumen
B. thylakoids
Chlorophyll is necessary for photosynthesis because it..
reacts with glucose
Which of the following DOES NOT summarize the energy changes in photosynthesis?
A. Sunlight is used to make food
B. Chemical energy is converted into heat energy
C. Solar energy is converted into chemical energy
D. Sunlight is used to build up complex carbon compounds
B. Chemical energy is converted into heat energy
