Sample NB Francophone G8 Science Practice Questions

Try these sample questions to test your NB Francophone G8 Science exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 60+ question experience with AI tutoring.

1Which organelle is known as the control center of the cell because it contains the genetic material (DNA)?
A.Nucleus
B.Mitochondria
C.Ribosome
D.Vacuole
Explanation: The nucleus houses the cell's chromosomes and DNA, directing cellular activities such as growth, metabolism, and protein synthesis.
2Which cellular structure is present in plant cells but absent in animal cells, providing structural support and rigidity?
A.Cell wall
B.Cell membrane
C.Cytoplasm
D.Endoplasmic reticulum
Explanation: Plant cells possess a rigid cell wall composed primarily of cellulose outside the cell membrane, which maintains cell shape and protects against mechanical stress.
3In plant cells, which organelles convert light energy into chemical energy stored in glucose through photosynthesis?
A.Chloroplasts
B.Lysosomes
C.Golgi apparatus
D.Centrosomes
Explanation: Chloroplasts contain chlorophyll, capturing solar radiation to drive the conversion of carbon dioxide and water into glucose and oxygen.
4What is the primary function of mitochondria in eukaryotic cells?
A.Producing ATP energy through cellular respiration
B.Storing digestive enzymes
C.Synthesizing lipids
D.Packaging proteins for secretion
Explanation: Mitochondria generate adenosine triphosphate (ATP) by breaking down nutrients during aerobic cellular respiration, earning them the label of cellular powerhouses.
5What role do guard cells play in plant leaves?
A.Regulating stomata opening for gas exchange and transpiration
B.Transporting water from roots to leaves
C.Absorbing sunlight for photosynthesis
D.Storing starch reserves
Explanation: Guard cells swell or shrink by osmotic pressure to open or close stomatal pores, controlling water vapor loss (transpiration) and CO2 uptake.
6During cellular respiration, glucose reacts with oxygen. What are the waste products of this metabolic process?
A.Carbon dioxide and water
B.Nitrogen and methane
C.Glucose and oxygen
D.Lactic acid and ammonia
Explanation: Aerobic cellular respiration converts C6H12O6 + 6 O2 into 6 CO2 + 6 H2O alongside ATP energy.
7Why do plant cells have a large central vacuole whereas animal cells have smaller, temporary vacuoles?
A.To maintain turgor pressure against the cell wall and store water
B.To synthesize proteins for export
C.To generate energy during dark cycles
D.To capture solar radiation
Explanation: The large central vacuole absorbs water, creating internal turgor pressure against the cell wall that keeps non-woody plant tissues upright.
8In plants, what process pulls water upward through xylem vessels from roots to leaves via evaporative cooling?
A.Transpiration
B.Respiration
C.Photosynthesis
D.Germination
Explanation: Transpiration is the evaporation of water from leaf stomata, creating negative pressure (tension) that draws cohesive water columns up the xylem.
9What is the mathematical formula used to calculate the density (d) of a substance?
A.Density = Mass / Volume
B.Density = Mass x Volume
C.Density = Volume / Mass
D.Density = Force / Area
Explanation: Density represents mass per unit volume, calculated by dividing mass (m) in grams or kilograms by volume (V) in cubic centimeters or liters.
10If a solid metal block has a mass of 120 g and a volume of 15 cm³, what is its density?
A.8 g/cm³
B.1,800 g/cm³
C.0.125 g/cm³
D.105 g/cm³
Explanation: Using Density = Mass / Volume: 120 g / 15 cm³ = 8 g/cm³.
