Example Questions
Example Question #31 :Cells And Life
Microscopic examination of a cell reveals that it contains many mitochondria. What does this observation imply about the cell?
The cell has a very low energy requirement
The cell has a high demand for removal of damaged organelles or of pathogens
The cell has a high demand for storage of genetic information
The cell has a high demand for neutralization of toxic compounds
The cell has a very high energy requirement
The cell has a very high energy requirement
Mitochondia produce energy (ATP) required by the cell, if a cell has large amounts of mitochondria this implies the cell has a high energy requirement.
Example Question #51 :Ged Science
Which of the following is not characteristics shared by both lysosomes and peroxisomes?
Removes damaged organelles or pathogens
Is a vesicle that contains enzymes
Is a membranous organelle
Is only found in eukaryotes
Performs an important function within a cell
Removes damaged organelles or pathogens
Only lysosomes remove damages organelles or pathogens. Peroxisomes degrade fats and other organic compounds as well as neutralize toxic compounds.
Example Question #41 :Cells And Life
Which is not a major function of the endoplasmic reticulum (ER)?
Storage
Transport
Phagocytosis
Synthesis
Detoxification
Phagocytosis
The ER has four major functions: Synthesis, storage, transport, and detoxification.
Synthesis - ER membrane contains enzymes that manufacture carbohydrates, steroids, and lipids.
Storage - ER holds synthesized molecules absorbed from the cytosol.
运输——物质旅行从一个地方到另一个地方within the cell inside the ER.
Detoxification - Cellular toxins are absorbed by ER and neutralized by enzymes in ER membrane.
Example Question #42 :Cells And Life
There are tiny structures found inside of every Eukaryotic cell called organelles. Each organelles carries out specific functions.
Which organelle is responsible for converting the chemical energy found in food into ATP (molecules that cells use for energy)?
Ribosomes
Mitochondria
Endoplasmic reticulum
Nucleus
Chloroplast
Mitochondria
The mitochondria is the "powerhouse" of the cell and converts chemical energy (sugars) into ATP during cellular respiration.
Example Question #43 :Cells And Life
Plants and animals are eukaryotes. They have many cell organelles in common, but there are also some differences.
Which of the following statements is true?
Animal cells have the following organelles that plant cells do not have: mitochondria, centrioles, and lysosomes.
Plant cells have the following organelles that animal cells do not have: chloroplasts, a cell membrane, a large vacuole.
Animal cells have the following organelles that plant cells do not have: centrioles, a cell membrane, and small vacuoles.
Plant cells have the following organelles that animal cells do not have: ribosomes, cell walls, and large vacuoles.
Plant cells have the following organelles that animal cells do not have: chloroplasts, a cell wall, and large vacuoles.
Plant cells have the following organelles that animal cells do not have: chloroplasts, a cell wall, and large vacuoles.
Plant cells have chloroplasts, which is the organelle where photosynthesis takes place, but animal cells do not. Plant cells contain both a cell membrane and a cell wall, but animal cells only have a cell membrane. Plant cells have a large vacuole and animal cells have small vacuoles. Animal cells have centrioles, but plant cells do not. All other organelles are found in both plant and animal cells.
Example Question #44 :Cells And Life
Organelles are tiny structures found inside cells. Each organelle has a specific function.
Which organelle is responsible for manufacturing proteins?
Rough endoplasmic reticulum
Cytoplasm
Smooth endoplasmic reticulum
Nucleolus
Ribosomes
Ribosomes
Ribosomes manufacture proteins, the smooth endoplasmic reticulum transports materials within the cells, the rough endoplasmic reticulum transports ribosomes which are made in the nucleolus to other parts of the cell, and the cytoplasm is the living material that cushions the cell and allows chemical reactions to occur.
