Science - Primary 6 Chapter 1: The Cell as a System & Living Systems

Chapter 1: The Cell as a System - Comprehensive Digital Assessment (2)

Advanced standardized digital assessment for Grade 6 Science Chapter 1 measuring experimental design, cell organelle pathology, bioenergetic efficiency, and chemical fire triangle principles.

Milestone 1 of 4 Round 1: Launch Questions (1 - 5)

Question 1 of 20 1 Mark

Why did Robert Hooke choose the term 'cells' when observing cork tissue in 1665?

Because they were made of iron prison bars

Because they produced electrical voltage like battery cells

Because the empty rectangular compartments reminded him of small monk rooms in a monastery

Because they moved like swimming fish

Question 2 of 20 1 Mark

Which of the following statements about cell membranes is scientifically accurate?

They possess selective permeability, allowing necessary nutrients in while expelling wastes

They are found exclusively in plant cells

They are completely rigid and impenetrable like solid stone

They are made entirely of pure liquid water

Question 3 of 20 1 Mark

What would happen to a plant cell if its cellulose cell wall were removed while placed in pure water?

It would duplicate into ten new cells instantly

It would swell and potentially burst (lyse) due to uncontrolled osmotic water influx

It would produce infinite amounts of wood

It would immediately turn into a diamond crystal

Question 4 of 20 1 Mark

Which organelle contains the enzyme machinery for the complete aerobic oxidation of glucose?

Endoplasmic reticulum

Chloroplasts

Golgi bodies

Mitochondria

Question 5 of 20 1 Mark

What is the primary role of chlorophyll during photosynthesis in plant leaves?

To store excess starch in underground tubers

To capture photons of light energy and initiate water photolysis

To absorb mineral soil ions through roots

To pump blood through vascular channels

Question 6 of 20 1 Mark

In what way do stomata open and close on the surface of plant leaves?

By muscular contractions powered by animal nerve impulses

Through changes in water turgor pressure inside the flanking pairs of guard cells

By melting in response to temperature

Through magnetic attraction with soil minerals

Question 7 of 20 1 Mark

Which of the following is an example of an organ system in plants?

The outer waxy cuticle layer

A single xylem vessel cell

Palisade mesophyll tissue

The shoot system (stems, leaves, flowers)

Question 8 of 20 1 Mark

What hierarchical level is represented by the human heart?

A complete independent organism

A uniform tissue containing only one cell type

A single specialized cell

An organ composed of cardiac muscle, nervous, and connective tissues

Question 9 of 20 1 Mark

How does spraying a wood fire with cold water extinguish the flames?

By increasing the concentration of atmospheric oxygen

By stopping the earth from rotating

By cooling the fuel: water absorbs heat energy, dropping the fuel below its ignition temperature

By transforming the wood into combustible kerosene

Question 10 of 20 1 Mark

What happens when a fuel is deprived of oxygen during combustion?

The fire expands into an explosion

Combustion halts immediately because oxygen is required to oxidize the fuel

The fire burns without producing any heat

The fuel turns directly into liquid nitrogen

Question 11 of 20 1 Mark

Which of the following organisms is multicellular and heterotrophic?

A human being

A cyanobacterium

A green algae colony

A wheat plant

Question 12 of 20 1 Mark

What chemical compound is the primary constituent of plant cell walls?

Chitin

Cellulose

Collagen

Keratin

Question 13 of 20 1 Mark

Which statement correctly describes cellular respiration in plant cells?

It occurs continuously day and night in mitochondria to provide metabolic ATP

It takes place exclusively inside chloroplasts

It consumes carbon dioxide and releases pure nitrogen

It only occurs when sunlight is completely absent for two weeks

Question 14 of 20 1 Mark

What is the minimum temperature at which a substance will spontaneously ignite called?

Ignition temperature

Sublimation point

Melting temperature

Absolute zero

Question 15 of 20 1 Mark

Which firefighting method is being used when a forest fire crew creates a cleared firebreak line?

Smothering: covering the entire forest with a blanket

Cooling: pouring liquid helium from airplanes

Starving: removing combustible vegetation fuel ahead of the fire

Electrifying the soil

Question 16 of 20 1 Mark

What is the function of the fine adjustment knob on an optical microscope?

To turn the electric light bulb on and off

To slowly and precisely sharpen the focus of the image under high-power magnification

To raise the stage several inches rapidly

To clean the glass lens mechanically

Question 17 of 20 1 Mark

Which component is present in eukaryotic animal cells?

Large central sap vacuole

Chloroplasts

Cellulose cell wall

Mitochondria

Question 18 of 20 1 Mark

What is the word equation representing hydrocarbon combustion?

Fuel + Nitrogen -> Ammonia + Steam

Water + Carbon Dioxide -> Fuel + Oxygen

Ash + Smoke -> Wood + Air

Fuel + Oxygen -> Carbon Dioxide + Water + Heat and Light

Question 19 of 20 1 Mark

What is the primary role of red blood cells in the human circulatory system?

Secreting digestive enzymes into the stomach

Contracting to pump blood mechanically

Transporting oxygen bound to hemoglobin from the lungs to body tissues

Transmitting electrical impulses to muscles

Question 20 of 20 1 Mark

Which of the following is considered an organelle rather than a cell or tissue?

A root hair

A neuron

Epithelial tissue

A mitochondrion
