Example Question #5 : Plant Biology
Which of the following structures is unique to plant cells?
Chloroplasts are organelles in plant cells that conduct photosynthesis; therefore they are unique to plant cells. All the other mentioned organelles can be found in both animal and plant cells.
Example Question #6 : Plant Biology
Which of the following can be found in plant cells, but not animal cells?
Chloroplasts, the site of photosynthesis, are only in plant cells and are not found in animal cells. Ribosomes, a cell membrane, and a mitochondria, however, can be found in both animal and plant cells.
The other structure that may be found in plant cells, but not animal cells, is a cell wall.
Example Question #7 : Plant Biology
Where in the chloroplasts does the Calvin Cycle of photosynthesis take place?
The Calvin Cycle occurs in the stroma, the aqueous fluid-filled area of the chloroplast. The stroma can be seen as analogous to the cytoplasm of a cell, in that it is the liquid in which all other substructures reside. The other processes of photosynthesis, the light-dependent reactions, take place in the thylakoid, a membrane-bound substructure within the chloroplast.
Example Question #1 : Plant Structures
Which of the following terms can be described as the green pigment located within chloroplasts?
Chlorophyll is what gives plants their green color. The chlorophyll located in the chloroplasts captures the light energy that drives the synthesis of food molecules in the chloroplasts—photosynthesis.
Example Question #2 : Plant Structures
Which of the following best describes where chloroplasts are primarily located?
Chloroplasts are found mainly in the cells of the mesophyll, which is the tissue in the interior of the leaf. Stomata are the pores that allow carbon dioxide to enter and oxygen to exit the leaf. The stroma is the dense fluid content of the chloroplast.
Example Question #3 : Plant Structures
What is the organelle in plant cells that contains chlorophyll?
Smooth endoplasmic reticulum
Chloroplasts are the organelles that contains chlorophyll. Mitochondria produce ATP and are not directly involved in capturing light and photosynthesis. The Golgi apparatus is involved in packaging substances, and Smooth endoplasmic reticulum are involved in lipid production.
Example Question #4 : Plant Structures
Inside the chloroplast, what is the name of a stack of thylakoids?
A stack of thylakoids is known as granum. Stroma is the region outside the thylakoid membranes, but still inside the chloroplast. Mitochondria is the organelle that produces ATP, and there is no such organelle called thylakoidum.
