Questions with solutions
Q1 — Seeds: Dispersal & Germination · easy · theory
The growing of a tiny new plant out of a seed is called …
A. Pollination
B. Transpiration
C. Respiration
D. Germination ✓ Correct
Solution: When a seed sprouts and a baby plant begins to grow from it, the process is called germination.
Q2 — Seeds: Dispersal & Germination · easy · theory
The scattering of seeds away from the parent plant to new places is called seed …
A. Melting
B. Dispersal ✓ Correct
C. Breathing
D. Digestion
Solution: Spreading seeds to new places, away from the parent plant, is called seed dispersal.
Q3 — Seeds: Dispersal & Germination · easy · theory
Which of these does a seed most need to start growing (germinating)?
A. Water ✓ Correct
B. Sand
C. Ice
D. Salt
Solution: A seed must take in water to soften and swell before it can sprout, so water is needed for germination.
Q4 — Seeds: Dispersal & Germination · medium · theory
A seed needs water, air and warmth to sprout. Which of these is NOT needed for a seed to germinate?
A. Air
B. Water
C. Bright sunlight ✓ Correct
D. Warmth
Solution: Seeds can sprout even in the dark soil, so bright sunlight is not needed for germination, though the young plant needs light later to make food.
Q5 — Seeds: Dispersal & Germination · medium · theory
The light "parachute" seeds of a dandelion and the winged seeds of some trees are carried to new places mainly by …
A. Fish
B. Wind ✓ Correct
C. Water
D. Heavy stones
Solution: These seeds are very light or have hair-like wings, so the wind can easily blow them far from the parent plant.
Q6 — Seeds: Dispersal & Germination · medium · numerical
In a tray, 20 seeds were sown and 15 of them sprouted. How many seeds did NOT sprout?
A. 5 ✓ Correct
B. 20
C. 35
D. 15
Solution: Subtract the sprouted seeds from the total sown: 20 − 15 = 5 seeds did not sprout.
Q7 — Seeds: Dispersal & Germination · hard · theory
A coconut has a light, spongy husk and can float. This mainly helps the coconut to be carried to new places by …
A. Water ✓ Correct
B. Bees
C. Wind
D. Ants
Solution: Because the coconut floats, rivers and sea water can carry it far away, so it is dispersed by water.
Q8 — Seeds: Dispersal & Germination · hard · theory
Some seeds have tiny hooks or spines that catch onto the fur of animals and onto our clothes. How are such seeds mostly spread?
A. By floating on rivers
B. By flying with their own wings
C. By being eaten by fish
D. By sticking to animals and people who carry them away ✓ Correct
Solution: The hooks make the seeds stick to passing animals and to clothes, and they are carried to new places before dropping off.
