GCSE Biology OCR Gateway - B1 Cell Level Systems

What is a Eukaryotic cell?

• A cell which does not have a nucleus.

• A single celled organism, like bacteria.

• A cell which contains a nucleus, like an animal or plant cell.

• A type of cell that can only be found in the human body.

Do all bacteria cells have a/multiple flagellum?

• No bacteria cells do not have to have any flagella.

• Yes but bacteria can only have a single flagellum.

• Yes and bacteria always have more than one flagella.

• Yes, and bacteria can have any number of flagella.

Does bacteria have DNA?

• No, only plant and animal cells have DNA.

• Yes, within a nucleus.

• No, bacteria are too small to contain DNA.

• Yes, in the forms of loops of chromosomal DNA, and plasmids.

What does a plant cell typically contain?

• A cell membrane, cell wall, vacuole, nucleus, mitochondria, chloroplasts, ribosomes and cytoplasm.

• A cell membrane, cytoplasm, rybosomes, mitochondria and a nucleus.

• A cell membrane, cell wall, plasmid DNA, chromosomal DNA and flagella.

• Only a nucleus and chloroplasts.

What is the reaction that takes place during photosynthesis?

• Carbon dioxide + Oxygen --> Glucose + Water.

• Glucose + Oxygen --> Carbon Dioxide + Water.

• Carbon dioxide + Water --> Glucose + Oxygen.

• Lactic acid --> Glucose.

Is photosyntheis and endothermic or exothermic reaction?

• Exothermic.

• Endothermic.

What is the balanced symbol equation of aerobic respiration?

• C6H6O6 + 6O6 --> 6CO6 + 6H6O

• C6H12O6 + 6O2 --> 6CO2 + 6H2O

• 6CO2 + 6H2O --> C6H12O6 + 6O2

• C6H12O6 --> 2C2H6O +2CO2

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration uses oxygen, whereas anaerobic respiration does not use oxygen.

• Aerobic respiration only takes place in humans, and anaerobic respiration takes place in plants and fungi.

• Aerobic respiration is the action of breathing, however anaerobic respiration is the reaction that produces energy.

• Aerobic respiration produces less energy than anaerobic respiration

How much ATP does aerobic and anaerobic respiration produce?

• Aerobic produces 32 molecules of ATP, anaerobic produces 2 molecules of ATP.

• Aerobic produces 2 molecules of ATP, anaerobic produces 30 molecules of ATP.

• Both types produce 30 molecules of ATP.

• Aerobic produces 30 molecules of ATP, anaerobic produces 28.

What is anaerobic respiration in plants and fungi?

• glucose --> lactic acid + carbon dioxide.

• glucose --> lactic acid.

• glucose + oxygen --> ethnol.

• glucose --> ethnol + carbon dioxide.
