Which of the following structures is unique to plant cells? Possible Answers: Vacuoles Mitchondria Lysosomes Chloroplasts Endoplasmic reticulum Correct answer: Chloroplasts Explanation: 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. Which of the following can be found in plant cells, but not animal cells? Possible Answers: Ribosomes Chloroplasts Mitochondria Cell membrane Correct answer: Chloroplasts Explanation: 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. Where in the chloroplasts does the Calvin Cycle of photosynthesis take place? Possible Answers: Stroma Thylakoid membrane Intermembrane space Grana Thylakoid lumen Explanation: 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. Which of the following terms can be described as the green pigment located within chloroplasts? Possible Answers: Photoreceptors Chlorophyll Mesophyll Stomata Correct answer: Chlorophyll Explanation: 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. Which of the following best describes where chloroplasts are primarily located? Possible Answers: Roots Stomata Stroma Mesophyll Explanation: 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. What is the organelle in plant cells that contains chlorophyll? Possible Answers: Smooth endoplasmic reticulum Mitochondria Chloroplasts Golgi apparatus Correct answer: Chloroplasts Explanation: 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. Inside the chloroplast, what is the name of a stack of thylakoids? Possible Answers: Granum Stroma Thylakoidum Mitochondria Explanation: 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. Which process is incorrectly matched with its location? Possible Answers: in the light independent reaction, G3P is produced in the thylakoid stroma in the light dependent reaction, protons are pumped from the thylakoid stroma into the lumen in the light dependent reaction, protons flow down their electrochemical gradient from the thylakoid lumen into the stroma, through the ATP synthase protein carbon fixation during the light independent reaction occurs in the thylakoid stroma Correct answer: in the light dependent reaction, protons flow down their electrochemical gradient from the thylakoid lumen into the stroma, through the ATP synthase protein Explanation: During the light dependent reaction, protons are pumped from the thylakoid stroma into the lumen. Then, these protons flow down their electrochemical gradient (from high concentration to low concentration), through the ATP synthase protein, producing ATP. Where is chlorophyll located? Possible Answers: Thylakoid membrane Mitochondrial membrane Thylakoid stroma Intermembrane space Correct answer: Thylakoid membrane Explanation: Chlorophyll is used to capture sunlight during the light dependent reaction; the excited electrons then flow down the electron transport chain located on the thylakoid membrane. During the light dependent reaction, the proton gradient is established. Where is the concentration of protons the greatest? Possible Answers: intermembrane space thylakoid stroma thylakoid lumen thylakoid membrane Correct answer: thylakoid lumen Explanation: During the light dependent reaction, protons are pumped from the thylakoid stroma into the lumen. Then, these protons flow down their electrochemical gradient (from high concentration to low concentration), through the ATP synthase protein, producing ATP. All AP Biology ResourcesWhat cell structure is found in plant cells but not animal?Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.
Which of the following structures can be found in plant cells but not in animal cells except one?The main difference between plant and animal cells is the presence of a cell wall. Animal cells lack a cell wall while plant cells contain a cell wall surrounding the plasma membrane.
Which of the following structure can be found in a plant cell but not an animal cell Quizizz?Plant cells have chloroplasts, while animal cells do not have chloroplasts.
Which of these can be found in a plant cell but not in an animal cell that is responsible for supporting the cell help with maintaining a rigid shape?Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.
